You should check the prices for my MTR w/kevlar, I have a set of 40's and 37's, those frickers arent cheap. But for your size I would assume you should be able to find something good in the 2-250 range. What are your uses for the tires? just mud?
Those look like they ride like shite. The old ones sucked arse in the mud too. Are they really that much better than the old ones?
My favorites as of recent are the Mickey T's. I had a set of MTZs and now have a set of ATZs. After going from 2 sets of old BFG M/Ts, 2 sets of Swampers, and a set of Mickey Thompson MTZs, I was amazed how quiet the ATZs are.
From my experience, which is much more than most, the Toyos, Pro Comps, and Nittos dont do that well in the mud. New KM2s don't do that well in the mud either. Just flat out don't get the Baja Claws or Mud Grapplers. They slide all over as soon as you get in any type of off-camber situation. If you want something that agressive, get SSRs. They are light years ahead of any other tire in the mud. You will be amazed at how well they pull. Had good road manners too. Can get them for cheap as all hell if you go to Rayne.
Best mud tires for the price, IMO, would be the MT MTZs, Goodyear Duratracs, or the Cooper Discover STTs. They all do better than most in the mud. I got ~40k out of my MTZs on a 7500lb truck. The Mickey Thompsons are expensive, but they are a very well designed tire. Only on-road mud tire I have ever seen better is the original BFG M/Ts
