Hi everyone, need some help.. Will these tires fit my 05 GT?? They are for the back and I am look at a set of the BF Goodrich g-force T/A KDW-2's... I want some thing "beefier" out back.. will this size get me that look? I'm worried about how off it will throw my speedometer.. any help would be awesome... thanks

 

Check Discount Tire's website. They have a tire calculator and other related info there.

 

Pretty sure if you want to stick with a diameter that won't through off the speedo you will need to go with 255/45's. They are very close to the stock tire diameter. Also, just so you know, it is not safe to go with anything wider than that on the stock rim.
