How wide of a tire can fit the stock ap1 without rubbing or anything? (front and rear)

 

Hugely depends on wheel offset.
Have a look at the first post here: https://www.s2ki.com/forums/index.php?showtopic=342793

 

You can safely run 225/50R16 front and 245/45R16 rear. The problem is the only tire I have available would be the Fuzion ZRI that would have matching tires.
If I can help let me know.

 

Im running 245/50 nittos in the rear and 225/50s up front

 

I've got 235/45r17's in the rear now and 215/45r17 in the front, and I'm thinkin of goin to 18's and will go probably 10 wider front and rear, and I wanna make sure I'd still be fine doin that and not mess stuff up. how wide of a wheel should I go? for fronts and rear? I'm thinkin 9 rear and 8 front. from what you guys posted I guess I'll be alright, thanks, I'd still like more opinions.

 

It all depends on what offsets the wheels are. Read: https://www.s2ki.com/forums/index.php?showtopic=342793
You could probably go with 11-12" in the back if they were the correct offset but if the offset is wrong then a 6" wheel will stick out and rub.

 

He mentioned on the stock AP1.

 

I know some turbo S's are running 255/50 MT's... so 255 is definately an option!

I lowered on the 245/50's about a 1.5"s with no problem!

 

Why wouldn't you run the 245/50/15 in the rear?

You all have the G-force sports I believe in that sizing with the 225/50/16 in front.

 

Bump for my question.
