Howdy out there, I drive mountain roads, both dirt and paved. Icy and snow packed 5 months out of the year. My first gen truck is 15 years old. I wore out a new 72 Ford 3/4 ton gasser. 2 trucks, 34 years of driving. In all that time I have never gotten more than 30,000 miles on a set of tires, design and Quality notwithstanding. The best traction was with a set of SEMPRIT All weather Radials (no studs) many years ago. Wish I could get a set of these again. (Busted thru bumper deep snow with no chains!). Uniroyal M-S w/studs were next as far as traction went. Michelin brand were not worth the price. 2 sets of Goodyear; one M&S w/studs-good when new, lost their bite quickly. One set Wrangler; not worth the money. All 235/85-R16 or 7. 50-16, 'E" or 10 ply radials. Still looking, Good tires can be had for under $110 each. Check "Big O" tires.
