I have 33"x10.5" on 15x7" rims Fitted to a Suzuki Sierra. They are a Bias tyre.
Off-road i have found them to be an excellent tyre, particularly on soft surfaces such as dirt and mud. On smaller rocks they are good, you can atually hear the lugs biting in, but on larger rocks, such as boulders sometimes it can be hard to get good traction. (although hardly ever a problem on a sierra with locker). Yet to test on soft sand. Mud is where they really shine. They have great side lugs too.
Basically, my Sierra is almost never stopped via a loss of tyre traction.
Airing-down - I run 8 psi off-road (with tubes) and there is virtually no bagging. Sidewalls seem very stiff. Don't have much tyre flex on rock. Probably would be better on a heavier vehicle.
On-road - Very noisy! They seem to handle very well for what they are, i really have no issue with on-road manners, wet or dry. I have a locked rear diff, and even in the wet it wont lose control/slide unless forced to. Also being such an agressive tyre, they dont chirp/squeal, or bounce around slow sharp corners with the locked diff like more conventional tread pattern tyres do.
Seem to have some vibration at high speed, but could just be my Sierra. Also looks like it took a fair bit of weight to balance.
When used on road the sharp edges of the lugs will wear to a more rounded shape. But it has actually made them a fair bit quieter since rounding off slightly..?
Sizing is also another issue. My 33" actually measure in at exactly 31.85".
Cost - I paid $260 each fitted (w/o tubes)
I would buy them again if i was on a budget, but if had a bit more cash to play with there are probably other better tyres on the market which suit a wider variety of terrains.
Pros - Off Road traction dirt/mud, price, side-lugs, look awesome
Cons - On-road sound, in-accurate sizing, grip on rock, vibration at high speed, hard to find stockist
