i have ran with both BFG MT's and TSL radials, i curently have the radieals on my 77 fj40 and they wore nicely, same as MT. personally i like the TSL excalent in off road and pretty good on highway or city use. i would go TSL's but thats juat my preferance
TSL's are quite a bit louder that the other 2. I can't hear anything between my burnt out glass pack and the TSL's in my 40. They are also a lot harder to balance that the BFG and MT/R. I do like them though. If you do a lot of on road driving, the BFG or the MT/R might be a better choice.
I currently run 33x12.50 mtr's, and on my last truck, ran 35's. I've also been through 6 sets of meats in the past 2 years (bfg at,bfg mt,swamper ssr,procomp mt, and mtr's
IMO the mtr's are almost too good to believe. The traction onm the rocks is awesome, I air them down to the 10 lb range. The on road is very nice, quiet, and suprising wet and snow traction for a non siped tire. They seem to wear well, and they balance easily.
Since you said "trail toy" I would vote for TSL's. I'm on my second set of TSL radials and really like them. My current ones are 36x14.50's. I don't have any weights on any of them and they run smooth down the road. And I don't need to hype the off road ability.
Someone once said - if it doesn't say Interco on the sidewall, it's an all-terrain.
