So i have to get new tires and i have the stock 245/65/17 on a 03 envoy. I have no lift and i dont want to add spacers but i am willing to grind the ball joint down. From the "will it fit" chart i see that i have either choice of 255/65/17 or i can go with the taller tire and get 245/70/17. I really would love to get 255/70/17 but from what i understand ill need a lift for that or spacers which im not willing to do. so what do you think?
