i have Micheln LTX on my i love them night day with handling from have the coopers on it well the was much wong with other then someone killed the side walls on them,i've had the michelin's on it now for bit and the the side walls are still in tract but the price tag is little high but i think there worth it !

On the tire subject I don't get near the miles out of my Toyo MT tires that I use to I'm lucky to get 25000 out of um now where when I use to get 45000

My brother had Cooper st on his 09 Duramax. I know he is good in keeping his tire properly checked and maintained, and he was not happy about treadlife of Cooper.

I've been buying General brand tires for all my vehicles recently and they are great! Look at the reviews online for different tires (I usually use tirerack.com), and you will see that they are one of the cheaper tires (not the cheapest though) and they rank right up there with Michelan, while being half the price.

For trucks I use the General Grabber AT/2, which is an all-terrain type tire. I've had them on my 1989 Chevy S10 4x4 for 4 years, and even in bad snow I generally leave it in 2wd because I can! I just bought 6 of these for my 1999 Cummins 3500 in 235/85R16 for $1000 out the door at National Tire and Battery, which is a great deal considering other prices I got ranged from $1200 to $1600...

I actually runnin BFG Ruff Terrains. I like em
