As much as the SVTPP wheels and tires add to the 2011 GT500's performance and handling, their size restrictions - combined with the lack of OEM PCM reprogramming for SVT vehicles - creates no small problem given that the stock F-1 G: 2s are the only tires available for the vehicle in stock sizing.
I'd like to put a set of all-season tires on 19" wheels that would allow me to make the car more drivable more of the year and keep the SVT wheels and tires set aside for track runs. Going to 275/40-19s in the rear and 255/40-19s in the front provide a reasonable amount of options sized closely enough to the original diameters to keep the telemetry from freaking-out, but not without the obvious penalty of reducing the amount of tire width by about 1/2" - and both the ability to put power to the road and to keep the car on it compared to a wider tire.
Ford SVT DOES offer some minimal guidance for winter tires (I'm guessing the lawyers made them provide at least a winter alternative given that some joker somewhere take his GT500 with F-1 G: 2s out on freshly-plowed snow, only to have his family sue Ford after his body is pulled from the wreckage. Otherwise, they're CIA silent about any other size recommendations - or even offering any kind of unofficial guidance as to maximum widths and sizes the GT500 with SVTPP can accommodate without clearance issues.
The wheel's I'm considering have a +33 offset, allowing me up to an extra 24mm of tire width before creating clearance problems (presuming equivalent diameters). What I'd like to know is just how wide I can safely go (front and rear) to improve both the performance and available selection of tires.
Any guidance or advice on how wide anybody has actually gone with tires on their 2011 GT500 with SVTPP would be much appreciated (including offset).
Thanks.
