RE: 15 inch rims? Cheap Mud Tires?
cheap mud tires: dunlop mud rovers..... i dunno what size you want, but i know for a fact theres a 31 and a 33 mud rover, i think theres a 35 but i aint sure
if you get 33 inch Dunlop Mud Rovers for a 15 inch rim its ~110 bucks..... for a 16 inch rim its about 130 bucks...... thats a 10.5 inch wide tire
those are the tires i have and their really really good, both in the mud and on the road. ive heard that Mud Kings are also cheap but i dont have experience with them, and i also dont know teh price offhand.
