BFG Mud Terrains KM1 32x11.5x15 tires with black steel rims
I was running 285/70/17 terra grapplers but I swapped with a friend for my current tires. Tires are much cheaper when you run 15" rims which is why I happily traded away my 17" rims. I plan on selling the tires I have now on craigslist & upgrading to 35x12.50x15 Goodyear Wrangler MTRs.
I was looking into guard dogs but realized that I couldn't get them for a 15" rim. They look great but I would be worried about getting a worn 2-ply sidewall core that could fail on the trails. I guess it just depends on how you use them.
