Im running 285 Cooper STT's on my 07 cummins, no problems with the front wearing out, but the rear is another story. Something about 650ft/lbs torque and a heavy foot i think. Truck was used in a concrete company pulling a trailer before i bought it so i know it has alot of highway and dirt miles on it. Ive put nearly 10k since i bought it and tred hasnt changed hardly at all. Definately going with at least 2 new STT's on rear before next winter. Love these tires so far.

 

How well do the cooper's clean themselves? In the mud.

 

I havnt played in the mud that much with them, but last time i did i didnt have any problems at all with them, real surpised how well truck went through the mud (even when i couldnt see out the windshield Does pretty good in snow to, no issues of snow packing in.

 

Thanks I have to look into them. $ if u know
