Just drove my 1st 100 mile trip with the new tires - very comfortable, but they're placing too much load against the gearing of the truck. It had a hard time staying in Overdrive on fairly mild inclines - something this truck's never had a problem with before.
See I ran 225/75's for the 1st 75k miles, then 245/75's for 71k miles, thought I'd like to switch to 265/75's - but it's not gonna cut it, think I'll resort to the 265/70's instead.
I like the wider tire, gives it better stability, and I like the looks of the taller tire; however I live in the Rocky Mountain region and if it can't hold overdrive on a mild incline, it's REALLY gonna bog it on Loveland Pass with a few hundred pounds of camping gear and a boat, even in 3rd gear, I can tell that it would have to work too hard.
