I had new tires installed on my 05 ss/sc. I went with a 225/45r18 instead of the 215/45r18. Well long story short my right rear wheel is rubbing my fender and tearing up my tire. I noticed that my left front sits in about a half in further then the right rear does.

 

are you lowered? shouldn't be rubbing with that little change in width

 

People run much wider than that w/o problems. I just bought that same tire size and will be installing shotly.

 

im on 17x9 wheels with 245/40/17's on sportlines and i dont rub. lol

 

iv been running 225 40s 18s for years now even when i was lowered to the max on coilovers i didnt rub and when i say max i mean i had to tuck the front tires under the fenders lol

 

yes i am lowered. I just dont understand why the right tire sticks out soo much more.

 

It's the extra height of the 225/45/18 tire. They are almost half an inch bigger than 215/45/18's. The fronts tuck in the fender wells more than the rears. Your camber could be a bit off up front also. I don't know why Tire rack recommends 225/45's. Most SS owners run 225/40's or 235/40's.

 

i just looked at the alignment sheet the camber, caster and toe are all perfect

 

I just got 225/45R18 's and notice rubbing on front passenger tire when front end loading (braking) and turning to the right. I'm guessing mine at least has more to do with diameter (9mm bigger overall than stock) than width cause it doesn't rub when going slow and turning for me...

Still I'm surprised nobody had mentioned this... and I can't seem to find anything hanging or loose in the wheel well.

 

I have heard of a few people having rubbing issues with 225/45/18's. That's why I always recommend 225/40/18's or 235/40/18's.
