I am running 255/85/16 tires. They have been great for sand,snow,mud, and even heavy rain. This is my second set of Mud terrians. I put over 43,000 miles on the first set.
I drive over alot of lava rock and they hold up great! The sidewalls hold up very well to the rocks. I have also used these to climb some really slimmy hills, with no problem at all.

They do not like icy roads at all. I have heard that sipping them helps alot.

Costco has one of the best prices. Lower than some dealers cost. Paid $137.00 apiece.
Best tire I have used for off-road use.
I would use the All Terrains if your primary use is on road.

Great Off-Road capability, basically the standard in Off-Road tires. Nice firm street ride. TOUGH tire that wont leave you stranded

Noisey, if you dont like the feel of tread at speeds of 20mph or lower, or the hum at highway speeds you wont like these tires, but their main purpose is dirt and mud anyway

about $150 a tire

These tires are very good mud and loose dirt tires they hook up great in the deep mud and I had a hard time trying to get stuck, they rock in the snow too.

The only weakness is the tires make ALOT of noise while driving on the freeway, and wet weather driving is tricky, they do not handle well on wet pavement, they slide alot.

they are good for solid off roading but not good everyday drivers, but they look bad ass!

BFG all terrain tires same size Much better in the wet driving conditions and MUCH quieter on the street, not as much traction in soft beach sand and or mud but the quietness makes up for it
