Mud terrains are hard composition?!? Where do you get your information from? if they were hard composition wouldn't they get better gas mileage? and if you look at an a/t's tread on the ground it keeps form, an m/t's tread tends to change form because the tread is soft. its soft so that it will grip to surfaces, such as...mud...

 

just had a look at the toyo site and it looks like i could get 315/55/R20 (33X12.50R20LT 114) on with out a lift kit, and no rub, pretty sure they are 9" wide rims. (stock tires are 275/60R20) (on a side note if i level the front could i get 35X12.50R20LT on it?) mainly use the truck for going to work (construction sites) and pulling my friends ford out of the ditch

 

Mud terrains for deep, unplowed snow. All Terrains for the hard packed stuff on roads and icy conditions...

 

seeing as how my building parking doesn't get plowed until like a week after the snow and i have to dig my truck out after a storm that burrys cars. Which is why i'm switchin to a M/T

 

My MT's have done real well in winter conditions. even on packed snow/ice they have done real well. But as stated before, driving styles has as much to do with it as tires.

 

I have Mickey Thompson ATZ's (35x12.50x20) - good on snow, not so great on ice. They have an awesome lifespan - 70,000 miles + if you keep them rotated.

I've had Interco Trxsus tires before and they were almost as good as snow tires on ice... They worked awesome in the winter. Downfall is not as great of lifespan, maybe 30,000 if you are lucky. I know a couple of Canadian aftermarket parts installers really recommend the Trxsus tires. They make them in bigger sizes like you are after.

 

My M/T's are still doing great in the snow, they are even fairly bald right now and still make it around in the snow. I say go with the M/T's
