Track Tire Question

frmla1fan · 03-24-2010, 08:00 PM

<UPDATED WITH OFFSET & BACKSPACING>

I just got a new set of wheels and tires (below) to track my stock '08 135i. I thought I found a thread that said 245/40/18 would work on the rear w/o any rubbing. Now today I see some folks complaining about rubbing at that size. I figure it could be the specific tire that makes the difference so if anyone else has tried this configuration with the Nitto NT01, I would appreciate some feedback so I can know if I should mount them or return them for another tire.

Wheels
Front: 18x8 ASA AR1 SML
Offset: 40mm
Backspacing: 6.10"

Rear: 18x9 ASA AR1 SML
Offset: 45mm
Backspacing: 6.80"

Tires
Front: Nitto NT-01 225/40ZR-18
Rear: Nitto NT-01 245/40ZR-18

what are the offsets. that is what is most important

245/40/18 is tall, and if the offsets are low then that will 100% cause rubbing issues.

post that info and I'll let you know.

That's an aggressive offset wheel for our cars. For daily driver use you'd probably be fine, especially if your suspension is not lowered. On the track I'm pretty sure that will rub a little too much to be tolerable.

I assume you can't get those tires in 245/35?

Nitto doesn't make it in a 245/35, in fact I don't see too many R compounds in that size. And as to the wheels, they were a recommendation from a local shop. I am really just trying to find the best set of wheels and tires to slap on for the track on the weekend. So I am willing to start over if someone can provide a good setup for the track. Everything on the car is stock.

Any help is appreciated.

a 245/40 is pretty tall, you would be an inch taller in the rear

i would say you will rub if you are lowered, stock, you may get away w/ it
