Friday night I took a couple friends up north of Index on some FS roads looking for snow.
I'm locked up at both ends running some Les Schwab MT knockoffs - 33x12.50.
My buddy runs a minitruck with 32x11.50 TSL Radials.
His friend runs a 99 TJ with 33x12.50 BFG MT's.
My buddy's dad drives a 96 LR Discovery. It's loaded, lifted, and locked. He just got some new 265/75-16 MTR's (more or less 32x10.50). He made us all look silly. He drove everywhere we went in 2wd. He broke trail for a while in 2wd and we NEEDED 4wd to follow. He put it in 4wd a couple times on slick descents just so the compression braking wouldn't kick the rear end loose. He never even used the ARBs.
My wife's Montero WILL be getting MTRs when the time comes.
Around here, it depends a LOT on what your intended use is. If it's a dedicated trailer queen that won't see snow, I think it's a tossup between the TSL SX and the Bias Irok. Dedicated rock buggies vary between the Irok and the MTR, but most of them travel to drier places for competitions.
For my cruiser, it will come down to MTRs and Swamper TSL SXs when the time comes. I drive it daily, but only a couple miles, so I can deal with poor road manners. For snow, rain, road manners, the MTR wins. The Swamper is better in mud, and has a tougher carcass (although I've never heard any complaints about the MTR).
I'm still undecided, but I've narrowed it down.
What kind of deal are you getting?
