I bought the rims directly from the Factory and they were selling me the exact tire sizes that are put on the RTR Mustang built by the race car driver. I told them I wanted the 285 on back and they wouldnt sell them saying thats not what they recommend and if i wanted different sizes i would need to get them elsewhere. I did find them cheaper at discount tire and wouldnt have to pay for shipping. What tires and sizes would u put bro?
Did they include TPMS sensors too?
I have the GT500 with SVTPP, so I have to replicate a 28" rear tire diameter of the 285/35-20 tires, so I need to go with either 285/40-19's or 275/40-19's.
Two potential problems exist with the 285/40-19. The first is that it exceeds the dimensions of the OEM tire, and the taller sidewall means even more give. Maybe it wouldn't end-up being a problem, but I'd be on my own if I did.
The second problem is selection. The only other A/S tire Ive found that come in matched sets with 255/40-19's for the front is the ContiProContact, but it's a touring - rather than performance - tire. A handful of of winter/snow tires exist, but I'm not going that route.
That leaves the 275/40-19's - and a WHOLE BUNCH more tires to choose from, including many all-season ultra high performance choices - albeit some expensive ones.
I've narrowed my choices down to Continental ExtremeContact, Michelin Pilot Sport A/S, or my likeliest choice - Bridgestone Potenza RE960 Pole Position.
I hate to give-up the extra 1/2 inch of tread width on the rear, but I'm going to have to make the devil's deal to make the GT500 drivable without the OEM SVTPP wheels and tires. It's also one hell of an expensive proposition, as this is going to be about another $3K before the car even comes off the truck.
I COULD go with a set of staggered aftermarket wheels, but that would leave out the RTR's, and I'd still be bound to a 275mm width. Because the SVTPP was basically built from the tire up, all of the geometry, suspension setup, and everything else is predicated upon a 28" rear wheel, and Ford has not yet (and may not) come out with a PCM reprogrammer for the SVTPP cars. And if you talk to Ford Racing or SVT Support, they won't offer the least bit of guidance beyond winter tire choices.
So, the best I figure I can do is stay within the original tire dimensions and shape, particularly at speed - and the 275/40-19's are the best and safest way I've found to do that. Unless somebody has a better recommendation to make.
