i have about 50,000 miles on michelin LT265/75R 16 E tires on my duramax mounted on 8 inch wide aftermarket Weld wheels .
they look good for another summer .
they have not needed to be rebalanced at all .
they are highway tread and are still quiet .
standard tire is a 245 /75R16E.
my experience is that the upgrade to 265 size gives me an additional 10 % in tire wear over the 245 . The load range E tire also helps the wear factor .
i run 50 psi normal and 65 psi when loaded / towing .
at 3415 # load rating per tire i am not afraid to load right to the 9200# gvw of the truck .
ride is a little rougher than the 245.
no punctures , ever , and we dry camp down gravel / unimproved roads .
