Has anyone run the XKR-S GT fitment P Zero Corsas (255/35 front, 305/30 rear) on their XKR-S?

I just ran Corsas on my Viper ACR at the track for the first time, and they really are a great R compound street tire. Of course, each tire is specifically built for the application... but I figure the XKR-S GT is pretty close to the XKR-S.

I was just looking at a set of these for my XKR. Seems to be a fairly good compound and design.

 

Just fitted 305/30 P-Zeros (not Corsas) on my 75, and I can confirm they don't catch the arches. They seem to give decent traction, but it's hard to say how much of that is simply due to having new tyres. The Corsas should be grippier, but wear faster.

 

Maybe the question is: what are the rim widths for these trims? I seem to recall that the GT has its own wheel?

The 75, R-S and Dynamic Pack come with 9" front & 10.5" rear wheels. Not sure of the rim width on the GT.

As I said, 305/30s fit on the 10.5" rims without any clearance problem, and they only affect the speedo reading by about 1% (counteracting most of the built-in optimism, i.e. the car & GPS indicated speeds are closer)

 

Good info, thanks. A 10.5" wheel is appropriate for 305 width, no problem.

I was looking at actual tread width comparisons between the P-Zero vs. Dunlop and there's half an inch of tread width difference at a 285 series.
Full inch between a Ventus and a P-Zero 10.1" vs 11"
Michelin comes in a 10.6" but do have significantly better tread-wear at 550 AA vs 220 AA Perelli Zero vs 60 AA Corsa.

Decent variance on tread-width at the 305 series too. I recommend using the compare feature on Tirerack.
