Ive had on cooper ATRs and yeah they dont wear too well on tarmac, but in the mud they rule... and yes expensive...
Next Im going with either Maxxis I think at $210 a corner, 245/75/16 which is an oversized tyre, oversized tyres are a good thing on 4x4s for economy and offroad handling...
I find my driving style has changed too, now any chance to go offroad I take it, even in shopping centre car parks, no free piece of land is off limits now...
