Anybody know a definitive way to tell the difference between the stock 18" rims...which ones are 8 and which are 8.5 (I think that's the width)? The dealership that put my tires on yesterday totally screwed this up the first time (didn't realize it was a staggered setup) and now I'm skeptical of whether they actually did it right.

 

On the back side of your wheel it will be marked as 18x8 or 18x 8.5. They put this on the back side of one of the spokes.

 

Cool. Let me see if I can squeeze my head back there

 

You have an 03 Touring. Both wheels are 18x8 +30s so it doesn't really matter which is which but it does say front and back on the back of one of the spokes on each wheel. I have a set sitting in my house right now.

 

on the center area of the Rays wheels where the tire wraps around, there's a giant F or R stamped on them

 

i thought the stock 18s (non-track) rims are both 8". I believe the front ones have a hole to match with the stud that sticks of the front whell hub to prevent ppl from rotating your tires.
