Can anyone tell me the formula to determine the offset of rims or can tell me the offset of my rims? I have rims that I am trying to get rid of but I lack specifics to sell them. The rims are staggered, the rears are 18x10 on a 235/35/18 with about approximately 2 inch lip and run flush to the body of the car. The fronts are 18x8.5 with approximately an inch lip which also runs flush. Any help would be greatly appreciated. Thanks

 

Oh and I failed to mention these rims were on a 2004 Acura TL

 

 

On the inside of the rim should be a stamp that say ET## (2 numbers). Every rim should have that stamp. That's your offset.
Here's an example.

 

Oh great! Thanks a lot I will check that out in the morning

 

1) Determine wheel width in mm then divide by 2. This is your centerline.



2) Measure wheel backspace, or distance between wheel mounting surface and inboard flange of wheel.



3) Subtract centerline from backspace. This is your offset.

 

Thanks guys for all your help, I'm such an idiot. My specs are completely off. I could have sworn these were 18s.

 

19x10 +38
19x8.5 +35

Haha! I have not been on this forum in since I posted that. And I've lost interest in fixing up cars. These rims have been sitting in the storage for quite sometime now and I totally forgot what they were... My bad dude lol
