Wheel Offset: What Is It?

Written by Jimmy Rustling

After purchasing your wheels online Canada, you will need to take your car to a garage or call your mechanic at your garage to have the old wheels removed and the new ones fitted. There are many things you need to make sure that is right during the fitting of the wheels. One of the challenges wheel changers get during wheel conversion is calculating wheel offset. Although you can know the procedure and be ready with everything you need, you might not get the numbers right. The best way to deal with this problem is first to know what wheel offset is, and get a basic overview of it.

The distance between the mounting surface and the center of the wheel’s width is what is called a wheel offset. Its measurements can be positive or negative, and they are measured in millimeters. Offsets of 0 are indicators that the wheel mounting pad is positioned in the center of the wheel. A positive one shows that the mounting pad is closer to the face of the wheel and with a negative one, the mounting pad is on the hub side of the centerline. You need an expert to fix your wheels online Canada. Even with that, there are some things you ought to know especially concerning wheel offset. Take a look.

1 All  That You Need To Know About Wheel Offset

Every wheel has an offset number printed either on the back of the spokes, into the barrel, or printed on the outside of the barrel. If you cannot trace your wheel’s offset, you can also measure it, and the procedure is easy.

However, some people don’t totally understand wheel offset and can easily misrepresent it. When getting accurate offsets, it is important to watch out for these things.

a. Wheel offsets are mostly abbreviated ET, meaning press depth in German.

b. You will realize that although most offset are presented with the abbreviation ET, some have a different prefix IS. ET50= IS5

c. Ensure the offset signs are correctly labeled. If it’s a positive, ensure it has a + sign and if negative a – sign. These signs might not seem important but they mean a lot.

2 Do Not Compare With Another Car

Just like the way your fingerprints are unique, so is offset. Do not compare your car’s wheel offset with your neighbor’s car. If you want to find out if wheels online Canada from a car similar to yours will fit, it is important to take measurements and calculations, just to be sure.

3 Getting The Right Size Of Adaptors

Once you have fully understood what a wheel offset is, your next curiosity would be to know how to get it right. There is some math to be done here, and this needs actual numbers that have been measured correctly. If you guess you will get everything wrong.

First get the base measurements. You will use this clearance factor to compare all the prospective Canadian wheels. The clearance factor is determined by getting the width and ET of your current wheels.

The formula for this math is;

(Wheel width/ 2) X 25.4 – ET + 10 = clearance factor

The reason you are multiplying by 25.4 is to get the measurements in mm. Do this calculation for the front and rear wheel separately.

The next thing is to know how the existing wheel feels in the car and you can know this by measuring. Get the distance between the face of the wheel and the inside of the fender. Once you have gotten that, add the results to your clearance factor.

4 How To Measure For New Wheels

For new Canadian wheels, you first begin with the first equation of finding the clearance factor. The next step is to add an adaptor to the measurements. This math is simple. To get this, you add the adaptor’s thickness to the clearance factor you got at the start of the calculations.

The equation for this is;

New wheel clearance factor + adaptor thickness = total estimated clearance

5 Your Tires Might Still Not Fit

Getting the total clearance factor is not a guarantee that your wheels will now automatically fit. When measuring, there are factors to consider.

a. Ensure you take the measurements at the same ride height you want to use the new wheels online Canada in when measuring the total clearance

b. Other factors on your wheel like the wheel camber, and characteristics of the suspensions will also determine where a wide wheel will hit
