I am pretty sure your GT rims are 17x8. I have a 2003 GT and that is what mine are. Any tire shop will tell you that the tires will mount to the cobra rims, but the tread will wear quicker on the outside than it will on the inside due to the fact that the tires are going to be stretched a little bit that will cause the inside tread to sink in a little and the outside will stick out a little. Same goes if you are trying to fit bigger tires on smaller rims. They will fit but the tread will wear out in the middle more since the tires will be pulled in a little to fit the rims. long story short, they will fit but will not last as long as they could otherwise. You may be better off trying to sell your GT rims and tires and get good tires for your Cobra rims. In the end I think you will be much happier.
