Hey guys. I currently drive a 18 Lexus is300 AWD Fsport if that matters. I am currently looking at a set of wheels that’s 18x8.5 with +33 off set on all 4 wheels and I’m putting 225 in the front and 255 in the rear. I was wondering if I would be able to fit that. Suspension and everything is stock.

 

The 225 would fit on a 8.5, although it'd be stretched
The 255 would also fit
If you could tell us the aspect ratios as well, I'm sure @Sasnuke will give you a definitive answer.

Are you just trying to reuse the stock tires?

Since you're squaring up the wheels anyway, I'd recommended going square for rotations.

 

They will fit, i'm running those specs lowered on RSR Downs (that's assuming the spoke pattern will clear the brake calipers)

I'm also running stock tires sizes without any issues on that setup. So as long as they clear the brakes, you're good to go (keep in mind, if you are AWD, you need to make sure the overall diameter will be the same on all 4 corners).

 

Yup! I am trying to reuse the stock tire

 

You'll be fine, see my previous reply.

 

yup! Just saw it. Thanks! I am purchasing rays gramlight 57xtreme. Saw them locally for a pretty good price. Bolt pattern is 5x114.3 which should be same to my car

 

Answer's got the answer for ya, just make sure about the AWD thing they highlighted.

 

yea, it’s AWD. So the rim will fit , I just gotta make sure that the tires diameter are all the same ?

 

Just to be sure. My front tires are 225 40 18 and the rear are 255 35 18

 

That's stock size, you're good!

 

Technically, isn't OP shrinking the diameter of the wheels because he is using a half inch wider wheel with stock tire sizes?

Edit: Nvm, the rear tire is the same size, the front would be a tiny bit smaller but I don't think it would effect the AWD system
