I have a set (4) of NT03s in 18x9.5 +40. And Apexi EXV Coilovers waiting to be installed.

What tire size do you guys recommend? My fenders are rolled. But not pulled. Please give me sizes in both, could be but doesn't have to be a square setup.

I just want something that fits without having to do anymore fender modifications.

 

245/35/18 should work for a square set up. Or 255/35/18 rears and 235/45/18 fronts. You will probably need to get an alignment and run about 2.5 degrees of camber to make these fit better.

 

I'm pretty sure you mean 235/40 F, and that would still be a lot taller overall than the rear. Best option is really going to be 245/35 all around.

 

I wondering how if 235 on 9.5s = too much stretch?

 

This is 235/40/18 on 9.5j



The issue is that if you go 235/40 in front, your OD will be 25.5"

Rear would be 255/35, which is 25" OD.

OEM is 245/40/17 which is 24.7" OD. Even if you did 255/35 R & 235/40 F, your front is going to end up .5" taller than the rear.

 

Ah you are right.

 

245/35/18 all around. Dont' go any narrower than that.

 

If I had that set up, I'd prefer to run a 255/35 rear and 245/35 front. Slightly smaller diameter up front is totally acceptable, especially on an ap2 where its biased to push in front, having the front slightly lower re balances the car to more over steer, which is really what you want. 235/35 up front would actually be preferred for clearance (245 is going to be a tight fit with that width/offset without pulling your fenders) But 235 on a 9.5" is clearly over stretched. So pull the front fenders and run 245/255.

 

Putting staggered tires defeats the purpose of getting non-staggered wheels.

 

Well when people get wheels that don't fit, sometimes they have to make compromises.
