I was wondering if anyone has noticed the sizes of tires. I have that brand of Firestone that was on the Exploders that were blowing out. They are about shot. My spare is a Goodyear RTS, when I out the Firestone beside the Goodyear the RTS is much taller. Both tires are 235/75/R15. When I asked a buddy that sell tires he couldnt figure it out either. And what I mean by taller is the side wall is taller in the RTS. I know that the tred depth is thicker on the RTS, but how can the tire be bigger that the Firestones but have the same tire size???? Thanks
