17x10.5 or 18x10 rear rims?

[jabGT]

I have 17x9 bullitts all around right now. I have to get new tires so I am going to replace just the rears with deep dish bullitts but can decide on the size. The 17's don't fill the wheel well (lowered 1.25"), but concerned on rubbing if I run large tires on the 18X10.

Any opinions?

Whats is the largest tire I can run on 17x10.5 and 18X10 with out fitment issues?

I would get 17x10.5 since you already have 17s on front. I have sumtiumo htrz 315/35/17s and eibach prokit with no rubbing.

I think you can get 315s on a 10" rim but it would probably fit better on the 10.5". I guess 17" vs. 18" really comes down to money. 18" tires, especially anything near a 315 size, are very expensive. I say if got the money, go 18".
