hi
i just want to say ,i had a 06 gt with stock perrelli tires and now i own a 07 gt with bf goodrich and i have to say i like the perrellis lot better when cornering. the bf goodrich have really bad like the tires feel like they are folding over on the rims,bump steer.the perrellis on the same corner,same speed,worked great!! they stuck to the turn,feeling like i really had control!! i wish ford would have not changed tires on the 07,that corning is bad with the bf goodrich tires. thanks jjgt06

 

Pirelli tires have always been a softer compound tire compared to most other tire manufacs. on the market. They also have SUPER stiff sidewalls so that performance is enhanced. I run Pirellis on my car. In the first 10,000 miles they were great for traction and handleing... now, not so much 10,000 after.

 

Did yours come with the BFG KDWS tires? Thats what I have and I love them! Feels great in the corners compared to my old tires.

 

It could be nothing more then a tire pressure issue.

BTW, why did you have an '06 and now an '07?
