How do I know what offset to use?
Wheel Offset Basics After so many years of publishing our Performance Handbook — 26 years and counting! — you might think it would be hard to pick our most popular stories. Surprisingly it isn’t. Based on our feedback, when we write about wheel offset, it is a social media sensation for us! And despite the exclamation point, that statement is not hyperbole.
So as part of the 100th anniversary of Modern Tire Dealer, we collected our wheel offset stories from 2013-2017 and combined them into a shortened primer for measuring wheel offset. If it leaves you wanting more, we can accommodate you. Just follow these three simple steps: 1) Go to ; 2) Click on our channel; and 3) download “” by Jacques Gordon.
It never hurts to be more informed about a topic so important to the handling and safety of a vehicle. — Bob Ulrich A car’s chassis is more than the sum of its parts. Everything from the shock absorber’s top bushing right down to the tire contact patch is designed to work together as one complete system.
- Changing the design or material or just the adjustment of any one part can have an impact on the car’s handling and braking, not to mention the way the car feels as it rolls down the road.
- With this in mind, there are three factors that consumers and service professionals must take into account when choosing and installing a different size of wheel.1.
Plus sizing. When you are changing the size of the wheels, the overall diameter of the tire and wheel assembly must remain the same to keep the proper speedometer and odometer settings. For example, when you mount and balance wheels that are an inch larger than the originals, the profile of the new tires must be an inch smaller in order to keep the same overall tire/wheel diameter.
In this example, the process is called Plus-One sizing. The same theory applies to mounting wheels one-inch less than the originals; in that case, the process would be called Minus-One sizing.2. Proper wheel size. The wheel must be the correct and approved width for the size of tire that it will carry.
A chart of approved wheel widths for tire sizes is available in the Ultimate Wheel & Tire Plus Sizing Guide (www.plussizingguide.com) and the Tire Guide (tireguides.com).3. Wheel offset. Perhaps the most important factor in choosing and installing new wheels is the proper handling of wheel offset.
However, it is important to get it right, because getting the offset wrong risks badly damaging the replacement wheels and tires as well as suspension components, and can put the driver at serious risk of a blowout.This article is about the basics of understanding and measuring wheel offset. FROM THE CONTACT PATCH PERSPECTIVE
Offset, scrub radius and contact patch are the only three technical terms we need to understand. You’ve probably read about “wheel offset,” typically described as the distance between the centerline of the wheel and the face of the wheel’s mounting flange where it touches the hub.
However, offset might be easier to visualize with a few simple drawings that focus on the tire contact patch.When the surface of the mounting flange is exactly aligned with the center of the tire contact patch, offset is zero. If the flange is inside the center of the contact patch (closer to the center of the car), offset is negative.
If the flange is outside the center of the contact patch (closer to the curb), offset is positive (see Figure 1). On most OEM wheels, offset is positive (contact patch slightly inboard), and it can have a major effect on steering feel and stability during acceleration and braking.
That’s because on the front suspension, wheel offset determines “scrub radius.” We can describe that by looking at how the contact patch moves in a turn. When the front wheels are steered left or right, the center of the contact patch doesn’t just pivot around a single point; it swings through a slight arc.
To visualize this, lay a pen on the table and hold the top end still. As you swing the other end left and right, the tip doesn’t move in a straight line, it moves through an arc. The radius of that arc is the distance between the pivot point that you are holding and the tip that moves through the arc.Now make another drawing to put that arc on the car.
- Looking at the car head-on, imagine a line drawn from the upper strut mount or upper ball joint and down through the lower ball joint, and then on down to the road.
- The distance between the center of the tire’s contact patch and the point where that line touches the road is the scrub radius.
- If the line touches the road inboard of the contact patch, scrub radius is positive.
If the line touches the road outboard of the contact patch, scrub radius is negative (see Figure 2). That’s the technical explanation, but here’s an easier way to remember it. The point where that line meets the road is the steering pivot point, same as where you held one end of the pen.
As the wheel is steered, the point at the center of the contact patch moves through an arc around that pivot point. The arc can be inboard (negative scrub radius) or outboard (positive scrub radius) of the pivot point, and the distance between the arc and the point might be just a few millimeters, but that small distance makes a big difference in what the driver feels in the steering wheel.
HOW TO MEASURE OFFSET Sometimes the offset isn’t printed on the wheel, or it might be printed in digits that are difficult to read or impossible to decode. No worries; it’s easy to measure offset yourself.Technically, offset is the distance from the hub mounting flange to the centerline of the wheel between the mounting beads.
- Since you can’t measure between the beads with the tire on the wheel, here’s an easy way to find offset by measuring from the tire sidewall.1.
- Lay the wheel/tire assembly on the floor and place a straight edge across the tire.2.
- Measure the distance from the floor to the straight edge and divide by two.
That calculates the centerline of the wheel. If the centerline number is smaller than the hub measurement, offset is positive; if it is larger, offset is negative.3. Measure the distance from the floor to the straight edge and divide by two. That calculates the centerline of the wheel.
- If the centerline number is smaller than the hub measurement, offset is positive; if it is larger, offset is negative.4.
- Measure the distance from the floor to the straight edge and write down that number.5.
- Divide that number by two to calculate the centerline of the wheel.6.
- Now measure from the hub flange to the straight edge.7.
Subtract the smaller number from the larger number. That gives you the offset of the wheel. If the centerline number is smaller than the hub measurement, offset is positive. On most cars, changing offset by just 5 mm is enough to notice a change in the car’s handling because it changes scrub radius by the same amount, and that might already be only a few millimeters.
- If the OEM wheels have a positive offset, you can safely install wheels with even more positive offset and use spacers to move the contact patch out to its original position, keeping scrub radius the same.
- Just make sure the new wheels and tires fit inside the fender without rubbing anything.
- If the new wheels have negative offset, there’s nothing you can do to move the contact patch in toward the center of the car.
The only way to know for sure how much the new offset will affect scrub radius is to put the car on an alignment rack. A FEW FINAL DETAILS Even if you’re confident the wheels have been properly selected for the vehicle, it’s up to your technician to make sure everything fits properly.
It’s a good idea to test-fit the wheel onto the front and rear hubs before mounting the tire. The first thing to check is brake caliper clearance: On OEM wheels it might be as small as 1/8 of an inch (4 mm). This can be hard to see, but it’s easy to simply install the bare wheel and turn it by hand. If clearance is that tight, the tech must take extra care when placing the wheel weights.
Mounting a tire on an aftermarket wheel versus an OEM wheel may be different; it depends on the location of the wheel’s drop center. Usually the drop center is toward the outside of the wheel, so the wheel is placed outside up on the tire changer. But some aftermarket wheels have the narrowest part of the drop center toward the inside of the wheel.
These must be placed on the tire machine inside up. If not, the machine will try to stretch the bead — which can’t stretch — and that can damage the wheel, the tire, the tire machine or the technician. Finally, make sure your techs tighten the lug nuts with a properly calibrated torque wrench every single time! Uneven lug nut torque is almost guaranteed to cause warped brake rotors within a few thousand miles.
Finally, remind your customers to come back after five to 50 miles to get re-torqued.3 THINGS TO REMEMBER ABOUT WHEEL OFFSET
If the new wheels are the same width, the new offset should ideally be within 5 mm of the old offset in either direction. If offset must be substantially different, avoid using more positive offset at all costs. If the new wheels are wider, backspacing must be calculated. The offset on the new wheels may need to be less to counteract the extra width. Offset must be carefully checked even if you are putting on different OEM wheels from the same maker.
COMPENSATING FOR WHEEL OFFSET If you have a service information system or an alignment machine with a built-in database, look up “steering angle inclination,” sometimes called “steering axis inclination” or “king pin angle.” On a vehicle where it’s adjustable, changing the angle of that line will adjust scrub radius to compensate for changes in wheel offset.
Some OEMs use this adjustment to set scrub radius on vehicles that are sold with different wheel size options. OFFSET VS. BACKSPACING Closely related to offset is the concept of backspacing. Offset and backspacing are often spoken of as if they are the same thing, but they are very different. Backspacing is defined as the distance between the mounting plate and the inner flange of the wheel.
Backspacing is, therefore, the combination of the offset and the wheel width. This comes into play if the new wheels are wider than the old, as the offset may need to change to compensate for the greater width. : Wheel Offset Basics
What does offset filter do in Photoshop?
Filter > Other > Offset Now, out of all of the filters categorised as ‘Other’ in Photoshop, this is probably the most common and most useful of them. Offset works by taking an area of pixels on the canvas and moving (offsetting) them along the X and Y axis.
What is offset in pixels?
Pixel Offset method – A pixel offset is a technique for measuring ground displacement, using a precise coregistraion between two SAR images. In this technique, a residual local offset after coregistration is regarded as an actual surface displacement.
- The figure shows SAR images acquired before and after an earthquake.
- In general, the satellite positions and its flight directions are different between the two observations，thus two SAR images do not match completely.
- This is why corresponding pixels (same ground target) between the two images have a spatial shift one another.
Applying an image matching with an accuracy less than 1 pixel, the positional displacement can be corrected, but there still remains the offset if there would be locally-distributed deformation. In the pixel offset method, a local residual offset indicated by a character of “K”, which is still remained even after a coregistraion between two images, is regarded as an actual ground surface displacement. Illustration of pixel offset analysis（after Tobita et al., 2001） Advantage
- Two displacement components are measurable: One is a displacement between the satellite and the ground target (RANGE component), the other one is a displacement in the satellite flight direction (AZIMUTH component).
- Large ground displacement is measurable: Suitable for crustal deformation observation for a large inland earthquake.
(NOTE: A standard InSAR analysis can measure only a range component, and in principle cannot measure large displacement of high spatial gradients) Disadvantage
- Low measurement accuracy : several ten centimeters
- Low spatial resolution: several hundred meters to 1 kilometer
(NOTE: For an InSAR, the standard measurement accuracy is approximately a few centimeters, and the standard spatial resolution is approximately several ten meters.)
What is offset cut?
Offset specifies the distance between your design and the cut path. This is a very important tool for fine-tuning fitment between two objects, or when cutting roughing and finishing passes when cutting.
What are the examples of offset?
Hint: Cynodon dactylon is the type of grass. Eichhornia is an example of an offset that is produced from leaf axils and from the new structure of the plants. Fragaria includes a group of strawberries. Mentha includes mint family. Meristematic tissues help in the development of offsets.
- Complete answer: The structure of the offsets forms when meristem regions of the plants, such as axillary buds or homologous structures, differentiate into a new plant.
- It becomes self-sustaining.
- They are mostly found in the species that develop underground storage organs such as bulbs, corns and tubers.
Offsets are the complete daughter plants. They are genetically identical to the mother plant. Offsets have stout and runners like horizontal stems. Examples of offsets are Pistia and Eichhornia. Cynodon dactylon, also called Bermuda grass, Dhoob, or durva grass.
They are native to most of the eastern hemisphere. It can also provide hay and pasture for livestock throughout the tropical and subtropical areas. Fragaria includes flowering plants and commonly known as strawberries for their edible fruits. There are mainly 20 described species of hybrids and cultivars.
Mentha is the genus of the plants in the family Lamiaceae that is also known as mint family. About 13 to 24 species of these plants exist. From the above information we can say that Eichhornia is the example of offsets. Therefore, the correct answer is option B.
- Note: Offsets are mainly found in rosette plants on water or ground surface.
- Water hyacinth(aquatic plant) undergoes vegetative reproduction that takes place through offsets.
- Offsets from the leaf axil and runs horizontally.
- They have a rosette of leaves and an adventitious root below.
- Offset propagates a new plant by propagating to a new niche.
Bermuda grass is used to make sports fields, parks, playgrounds, golf courses and other general purpose turf.
What is a 33% offset?
3.1/3 or 33% Offset. This is a twist on the basic offset pattern where each tile’s edge is only offset by one-third of the width of the tile above or below.
What are the two types of offsets?
Offsets in Chain Survey – Lateral measurements from the baseline are termed as offsets. They are used to fix locations of various objects with respect to the baseline. Commonly, offsets are established at right angle. There are two major type of offsets, namely: perpendicular offsets and oblique offsets. Fig.5: Perpendicular and Oblique Offset
How do I find the offset of an image?
The percentage is directly related to the image height. If you want to calculate the image offset, you would multiple the percentage by the projected image height. This calculation will tell you the estimated distance between the lens center and image bottom (table top installation) or image top (ceiling installation).
Where do I find resample in Photoshop?
How to Resize an image in Photoshop (and when you should Resample instead) Resizing an image sounds like one of the simplest things you could do in Photoshop, but there are actually some common mistakes you should avoid. In today’s digital age, you will probably want to resize an image so it fits nicely on a computer screen, however, if you’re a professional designer or photographer, it becomes a little more complicated when you need to factor in print size and resolution. In today’s guide I’ll cover the basics of resizing an image in Adobe Photoshop, and explain when you should (or should not) choose the Resample option. Unlimited Downloads of 2,000,000+ Brushes, Fonts, Graphics & Design Templates Ad Resizing and resampling are two confusing terms because we tend to use them the wrong way round. We often talk about resizing an image, when what we are actually doing is resampling it! In Photoshop, go to Image > Image Size, or hit the CMD (or CTRL on Windows) + ALT + I shortcut. By default, the Resample option in Photoshop is checked, which will mean the dimensions of the image will change by adding or subtracting pixels from the width and height. This is known as resampling, and it’s usually what we’re doing when altering the size of a digital image. If the Resample option is unchecked, you’re now Resizing the image. Photoshop will now redistribute the existing pixels to alter the physical size or resolution of the image. This is typically reserved for graphic designers and photographers who are producing prints. The Image Size window in Photoshop shows the current size of the image. Change the units to Pixels if they aren’t set already. Pixels are the standard unit of measurement for digital screens. Enter your desired pixel dimension in either the Width or Height field. The Constrain Aspect Ratio’s chain icon is set by default to automatically calculate the other dimension so the image isn’t squashed or stretched. Photoshop provides some information at the top of the window showing the new file size compared to the original size of the image.
- Images are made up of pixels.
- The number of pixels along the width and height of an image determines its size.
- It’s easy to make an image smaller because any excess pixels can be thrown away, but if you want to make an image bigger, Photoshop has to conjure up some new pixels to construct the larger size.
This is called Interpolation, The general rule of thumb is to never make an image bigger than its current size because it will result in degraded quality with a fuzzy or pixelated appearance. However, the technology behind Photoshop can cleverly upsample an image with the best results possible. By default, Photoshop will choose the most suitable interpolation method itself with the Automatic option, but you can have finer control over the result by choosing one of several options. Each one is designed specifically for enlargement or reduction.
- Upsampling an image will never be perfect, but you can minimise the image degradation by smoothing or preserving details, depending on what works best for your specific picture.
- Traditionally, 72ppi is the go-to resolution for screen use, while 300ppi is the standard for print.
- PPI (pixels per inch) refers to the digital file, which translates to DPI (dots per inch) when the image is reproduced as a print.
These terms are often used interchangeably. A high-quality 300ppi stock photograph will be perfectly suited for print use because it has a combination of large dimensions and high resolution. On the contrary, a 72ppi image might look huge on screen, but the maximum size it can be printed at 300ppi will be pretty small because those 72 pixels in every inch will soon run out when you need to fill each inch with 300 pixels resulting in a smaller print size. We know upsampling should be avoided to prevent image degradation, but you can increase the resolution of an image as long as you DISABLE the Resample option. If you don’t, the image will say it’s 300ppi, but thousands of new pixels will be interpolated by Photoshop, resulting in awful quality. To correctly change the resolution, the image should be resized (not resampled). Uncheck the Resample option, which prevents you from altering the pixels dimensions of the image. You can then change your 72ppi image into a 300ppi image, but notice how the physical size in inches is reduced? Resizing only works with the existing pixels, without interpolating any new ones. You don’t have to physically change the resolution of all your images when constructing a design. If you create a canvas at your desired dimensions and resolution, whenever you paste an image into the canvas, it will be automatically scaled relative to the document resolution.
- Remember not to scale your layers larger than their original size either.
- That is effectively the same as resampling them.
- Scaling down = Good.
- Scaling up = Bad.
- That’s why it’s important to source your assets such as photos and textures at the highest size and resolution possible, so they will be usable in real world projects like posters or canvas prints.
