tire question

[s13400hp]

I have a quick question I have 18x9.5. Offset 30 and I was wondering will 245-40-18 fit on that rim and not sticking out of the fenders

I would suggest going with a 235/40 if your not sure.

Also different brands on tires stretch differently.

Better to run smaller than go wider if you have room.

Also it helps if you had adjustable RUCA.

But I think you should be fine.

Actually that'll fit right on a 9.5 just fine. Doesn't even go out of spec.

Check out the wheel fitment thread. There should be quite a few guys running setups pretty similar. You can see how it looks.
