I have a 97 GP GT and recently got some 18's for it. they have 245 40 18 tires on the rims. My problem is my ABSand trac off light kept coming on at first. It would reset after turning it off and back on but would do the samething periodically come on and stay on. . Now it just stay on all the time. Never did this with the stock wheels on. Whats goin on? Why now with the different wheels and tires on it?
