I'm Running 265-75-16 Pro Comp Xtreme M/T.
They seem to be good tyres, both on and off road. Bit of road noise but not bad.
They're my first set of mud tyres so I dont have much to compare them to.
They were on the truck when I bought it, I was told they had done about 30-40 thousand kms. Ive done another 20 or so thousand, still got a fair bit of tread left, dont seem to have worn down in the time I've had them.
I think they are about $420 a tyre, so not cheap. I'm happy enough with them that I would buy them again depending on how the prices compared with other tyres, then again for an all round tyre they seem to be wearing well on road so maybe the price may be worthwhile.
