Wheel Offset

What is wheel offset? Very simply stated, it is the distance from the hub mounting surface to the centerline of the wheel. It is measured in millimeters and can fall into one of three categories:

Zero wheel offset occurs when the hub mounting surface is spot-on with the centerline of the wheel. Positive wheel offset occurs when the hub mounting surface is positioned toward the front of (or, wheel side) of the wheel. On the other hand, if the hub mounting surface is positioned toward the brake side of the wheel, then we call it negative wheel offset.

Wheel offset directly affects the way a car handles. Therefore, if the offset of a wheel isn't correct for the particular vehicle, problems will ensue. At Tire Rack, we test fit thousands of vehicles for proper fitment to create an extensive database—we use that information to ensure the wheels you order fit the vehicle you drive.

I would like to put 91 Stock Corvett rims on my 87 Corvette. My 87 has 16x9.5 rims with 38mm offset. The 91 rims are 17x9.5 with 56mm offset. Will the 18mm difference in offset be a huge problem? I t is getting harder and harder to find the correct 16" tires as you know that sizing 16x255-50 only applies to Vettes from 84*87. I believe 18mm translates to about 3/4 of an inch. Thanks for your help.

Hello Tony,
It is hard to tell. We test-fit every application here at the Tirerack to ensure proper fit not merely based pure specs, but CAD fitments as well. We do cannot approve any OEM wheel fit from one vehicle to another. 18mm is about 3/4", and on paper, it looks close, but this is something that you may have to test fit yourself and spin to see if it clear the brakes. Another thing to consider is the possibility of needing hub-centering rings as well. I hope it all works out for you.

What is the correct oem wheel offset for the Audi A8L for the 17" and the 18' wheels?

Thank you for your inquiry. Unfortunately we do not have the wheel measurements for those stock A8L wheels. Although we have many fitments that are gauranteed to fit, your inquiry is one that will require a call to an Audi Dealership.

I am looking at purchasing a near new set of wheels from a private party. They were mounted on a 78 MBZ 450SL. They are 15x7 OJJ. They are not the stock wheels that came on the '78, rather the 90s factory style wheels that are on my car.
I want to put them on my '95 MBZ e320 Wagon. Will these wheels fit? I will need new tires regardless.

As this is not a Tire Rack part number I sadly cannot gaurnatee the fitment. -Marshall@tirerack.com

I am contemplating buying a 2013 Infiniti FX50 to replace my 2009
FX35. I currently have 265/R60/18 winter tires that I purchased from you for use on the FX 50 which comes standard with 21" wheels. Given the limited number of winter tire choices with a 21" wheel. Do you feel this is OK. If so, I also wish to buy a new set of 18" wheels. Please let me know wha the proper offset would be for the FX50. Thank you.

It is OK to use 18" wheels on the FX for winter. For wheel selection use the following link:

Select build your own package, and then skip the tires (since you already have them). -ben@tirerack.com

I have a set of BBS RGR 18*8.5 with 38mm offset. Would I be able to fit them on e93 or e92 M3 as winter? Thanks.

Tim the 38 offset is higher than recommended for the M3. That would be better suited for a normal 3 series. -ben@tirerack.com
