335 80 20 tires, these are the factory tires off of a Unimog. They measure 41" tall. 335/80r20 MPT81 tires are load range M, and this set of 4 have plenty of life left with 11-12/32nds. I've driven other sets of these military tires on my heavily modified 2002 Silverado and they do great at high speeds, I've towed heavy trailers cross country running this rubber. Can't beat the price for a 41"!
