RS4 Vin

What size tire would have the largest tread width that would fit on a 2007 RS4 with 19" x 9" RS6 five-spoke wheels with an offset of 35mm? The spec's for the stock 2007 RS4 wheel and tire sizes are as follows: 19" x 9" with 29mm offset, tires are 255/35 ZR19. I believe the PZero's have a 10" section width. Any assistance or comments would be appreciated.

Letting air out is the quickest way to increase the size of the tire patch.

I assume that you want to stay with 355-35-19s, BFGoodrich KDWs run wide. Yokohama Advans do too.

Yes...that's a good idea. But I was looking for a bigger impact on the appearance of the tread width of the tire (i.e. a fatter tire). A Corvette Z06 has a tread width on the rear tires of about 11.6". What size tire can I go with that will make a signifacant change in the width and still work on the RS4? I'll make calls to Hartmann and Tire Rack tomorrow, I just thought some of you guys/girls may have some ideas.

B5 S4 OEM 225s safely upgradeable to 235s
B6/B7 S4 OEM 235s safely upgradeable to 245s

I assume that 265-35-19 would work just fine. Added tire height will actually make the fender gap smaller. You are right about calling Hartmann.

Focus instead on a better performing tire. A good 255 tire > a mediocre 265 tire,

Tomasz@Startup

he is not looking for more grip, he is looking for a wider tire

I guess if he's just after looks he could have picked up a used A4 3.0 unltrasport instead.. I hear those are pretty much as fast as the RS4.

if you're going for absolute performance, you'd be better off adjusting that loose nut behind the wheel.

For Appearance Only...at this point. I haven't even driven an RS4 yet.

Tomasz@Startup

Yup, I agree for performance better tire compound may be all that is needed.
