I have an '04 Mach 1. Time for new tires. The stock tires are 245/45/17s. I am going to change springs to lower the car an inch or so and need to know what larger size tires can be mounted on the stock rims??

 

I believe 275/40/17 all around. I think alot of people may just do the rears tho.

 

The largest size we show that will fit on your stock rims is 255/45-17
