look on the inside of the wheels for the offset.

 

ya my guess the offset is wrong for the car or your shocks are shot, do you have a pic? I have 18's on my car and mine is slammed where i may only have a few mm's between tire and fender and I don't rub at all.

 

I was just looking at my tires. They stick out further than the wheel well, if that makes a difference. I can't remember the whole thing i wrote down...which i will check tomorrow, BUT i'm pretty sure it said something like 245/40ZR 18 90W for the rear and 225,40ZR 18 75 for the front.

I dont remember exactly but i know i'm close.

I'm not seeing where there is the offset or whatever written.
Is it on the tire? the actual rim? Inner side of the tire?
I don't know what im looking for

 

wheel offsets are usually posted on a sticker on the inside of the wheel

 

You are rubbing, not bottoming out. If the rub is minor (like what I have) you will be fine, and not cause any damage. If it's rubbing on flat turns, then you have issues that need fixing.

 

if your tires are sticking out further than your wheel well then the offsets are too aggressive. For the rear you may be able to get an aggressive alignment with -2 to -3 camber and that may solve the rubbing issue.

 

... and give you a nice expensive tire wear issue.

 

well ya that goes without saying actually that isn't too bad as long as you rotate your tires. Albiet you would haveto dismount and remount your tires/.

 

I guess it's not that bad. It's only when i'm going fast 50+, and hit a big dip in the road where the car will drop fast. It makes a chirp contact and thats it. I guess it's not much to worry about is what i'm hearing. I'll just be more careful as i go over dips.
