I have had several tire types... just like everyone else on here I have an opinion also...
the Mickey Thompson MTZ's I put on my rubi have done very well on the trail and on the street.
I have herd that they wear fast, but that is what happens when you want a softer tire to offroad with, they wear faster. It gives me a chance to upgrade faster ;D
BFG MT's can be scary in the rain and snow (on road) but they are harder so under a lighter Jeep they should last a long time,
I have used Kumho MT's and for the price they were great, but same as BFG in the rain
My wife has Bridgestone Duellers on her SUV and they are great onroad in snow and ice.
As far as getting a good deal, Qtech and 4wd are overpriced, even with the discount...
tirerack is good but they have limited selection.
the best deals I've found were at Summit Racing and Jegs, best prices and shipping is cheaper also
