Hello I have a 2008 is250 RWD, I found some cheap Tenzo Tenspec rims $500 for a set, but the rear wheel is 235/40/18 instead of 255/40/18 like stock. I was wondering if anyone has those rims or that size and if it will have any effects on the car since they are a bit skinnier.

 

Sounds like ride quality is about to get harder.

 

You'll be fine running 235's. I believe the stock 17" rims are a square setup, 225 or 235 all around.

 

But I don't have stock 17s I have stock 18s with 255/40/18 in the rear. If I put a 235/40/18 in the rear will it be a lot more harder?

 

A lot stiffer ride...not really. What is the offset?

 

It doesn't have the offset measurements listed on the ad, but is there anyone that has these rims on their 2IS
