The Coopers will well outlast the Maxxis for kms travelled. Plus the Coopers are known as stickier in the wet than the  Maxxis. Pretty much you get what you pay for with those brands.

Run Kumho KL71'S on our last 3 4wd doublecabs. Had Coopers on the first one, but did not like the way they handled on the road, so changed to the Kumhos.
Always check prices, with Steve at TyreShopOnline before you sign up, great guy to deal with. A wealth of practical experience, along with sharp prices,  free freight if you buy a set of 4 tyres. 

I had Maxxis tyres, mudders i think they were called. I guess they were a hard compound tyre as they lasted 80,000km. However you would not of wanted to do any hard cornering as i always thought they would let go, if it was the compound or tread pattern i dont know ?

I now have Cooper tyres from Mag and Turbo here in ChCh, they are a less aggressive mud tyre. They rotate them "free", as in built into the price ? every 10000km. Very easy to deal with. They said i should get 80000km out of them. I also feel a lot more confident I wont have let go experience when i need them to hang onto the road.

I had coopers STs on my old Nissan patrol,tyers got hammered on the Tekapo river for a few years.Got a 110000 ks out of them down to the copper wire.The next set were $600 per tyer.Bugger that, went to bfgs.
