I love my 2002 duramax ( bought new ) in every way except one .
It is a rough riding son of a gun .
I upgraded the factory 245/75r16 load range E tires for Michelin Highway 265/75R16 load range E on my 1997 vortec 7400 and again on my 2002 duramax .
I have about 60,000 on these now and they are not to the wear bars yet .
The Mich 265 made my cornering better .
I run a little less pressure and at 3415 # payload each i have no concern loading up to the 9200# payload .
running around weight is about 6800 # .
I have been shopping tires lateley and thinking about using the softer P rated tires that weigh about 80 % of the load range E tire .
In the end I can say that these michelin highway tires have been very quiet throughout their life and have cost me no more per mile than cheaper tires that will only go 45,000 miles or less .
