I have a 2007 c6 corvette with aftermarket rims and tires. I brought the car used from the dealer and took it to service and they said they cant do nothing because the car has aftermarket rims and tires. Every time i go over 60-65 mph i get a message saying Traction System Active so i either have to take traction off or go to competitive driving mode. If anyone has had this problem before or knows a solution please message or post here, Thanks.

Tire sizes? If off in the OEM too much, this will happen. Info thanks to the CF members.

Can you list your tires (Brand, model and sizes) info.?

They are nitto invo. The front is 245/40zr18 93w and the back is 285/30zr19 98w

Theres the problem; The rear tires are supposed to be a 35 aspect ratio. The 30 ratio is smaller and the computer thinks the rear wheels are spinning when it compares the front rotation to the rear. Get the correct size rear tire and your problem will go away.
