Hey everybody, does anyone know what the max size tire one can run on the 06 coupe 19" rims? I am currently running:

225/40/19 front
245/40/19 rear

Look at this thread:

I am running 265/35/19 on the rear. The side walls are perfectly straight (no bulge). As an added bonus, my rims are protected. Dont let anyone tell you that this size won't fit on the rear.

Thanx Res, that helps alot and drops the price about 100 bucks a pop!! What are you running on the front?

245/35/19. Potenzas in this size on close out at Tire Rack for $141.

Does anyone know if 275/35/19 will fit on the stock 06 19" coupe rims?

I'm in a bit of the same dilema right now. I went in to buy two new rear tires (245/40-19 Michelin Sport PS2), and they are on a national back order through Michelin for the next six weeks. My front tires have about half the tread left on them, so I only was looking at buying rear tires. The other problem is that I don't want to mix different brands of tires front to rear. What I ended up working out is that he would give me half credit on the fronts as long as a bought a set of four new Michelin PS2's. The sizes that we figured out (because of the VSD issue and not wanting to alter the OD that much) was 245/35-19 for the front and 265/35-19 for the rear.

I came on here this morning to see if anyone else has tried it, and it seems to me that it should work. One concern I have is that the footprint of the tire will be different (wider but shorter) and I didn't know if anyone had fooled around with tire pressures or even alignment settings to see how this worked. Also, I was wondering if anyone had any comments on how the car behaved with this different setup (ie. handling feel, griup levels, ride). I've concerned that a wider tire on a smaller wheel wouldn't return the same crisp handling feel of the stock setup.

275/35/19 will fit the rears

the max for the rears 285/30/19

275/35/19 WILL require 9"+ width, OEM 19'' is only 8.5". Although, some people have done it.

285/30/19 WILL NOT fit the oem 19". Unless you dont care about the huge buldge or any safety.

yes they will. i have a set at home that i'm waiting to get installed on my rear rims right now.
