You are correct. I was thinking about the 265 60 18s tires that came with my JGC ORAII package. Thanks

With 10" 50mm offset vs OEM 8" 54.5mm offset (same size tire):

Suspension 100% clear (leaves even more room than OEM)
Fenders Package will stick out 4 mm (0.2'') farther. Acceptable for most cars.
Wheelwells The same.



10" wide rim with 50mm offset should have same/more clearance since the tire width/height remains the same. I know it's not a good idea to get a rim with an offset much different than OEM so I want to stick within 10mm of OEM. The SRT Rep 9" rims have a 34.7 offset compared to the 54.5mm OEM. That will make them stick out 19.8mm or ~.8".

I would try the 10" 50mm offset rims all around unless someone knows of a reason that this wouldn't work.

Thanks everyone.
I thought the offset for the stock rim was either 56 or 58? yeah, I read the part about it clearing the suspension. I was just trying to find someone that is actually running them to be sure. I'm pretty sure they will work I just wanted to get it from the source. I wish they wouldn't stick out any more than the stock rims but if it comes to that or rubbing then I would rather have them stick out a little. The 10" rims are too wide...if you think about it that extra 2 inches has to go somewhere...either to the inside or outside...which could cause rubbing or it sticking out.

Thanks

Yeah I starting thinking about that after I posted. Although what's the width of the tire at its fattest point when mounted on a 8" rim vs mounted on a 10" rim? It will be wider than the 8" rim for sure and should also be wider than a 10" rim (265mm wide = 10.4"). The tire might look a little funny stretched out over a 10" rim (no rim protection, etc). Although I know some people like that look.

Looking at specs on some 265/50 wide tires I see the widest rim they recommend is 9.5". Looks like you would need 275/45 tires to fit over the 10" rim.

I think as long as the overall tire width is wider than the rim then the rim width shouldn't matter much for clearance. The tire would hit before the rim.

EDIT: Looks like stock offset is 56mm. Not sure where I got 54.5 from....
