I've been looking for a 30in tall tire for the rear of my Dodge. I looked for a 285/70/15 but it seems nobody makes them anymore. I can get a 275/60 on it but they are 28in. Anyone know of anything that don't cost a mint? I'm not going to have a OD trans, and my rearend has a 3.42 gear. Trying to keep the rpm down when I have to hit the interstate.
