Im thinking about getting some new tires for my dd- 99 dodge ram 3/4 ton. The tires on it now are brand new 31" firestones. But i wanna get a lil bigger tire on there. Im looking at tires in the 315/75r/ 16 range. Im looking at the pro comp extreme mud terrains. I can get the lt315/75r/15 for $252.80 from NTW online. They have a deal buy three get one free. So like $750 for all 4 tires. What do you all think about these tires? Thanks brad.
