On the tires - They come on the 6 wheelers in the military which is considered a Light Armored Vehicle. Each tire is rated for 4580lbs. They are heavy. Fit on a 16" x 7" (or 6") wheel. This tire has a VERY lowing rolling resistance. 38.5" tall by measuring tape
As with any tire they are not the best for everything. You wouldn't use them for rock climbing.
But for the best idea of how they perform, here is a friends old m715 in the mud. Same exact drivetrain as I have. Watch it and you should be impressed. At one point the two vehicles being pulled had their brakes on and he never slowed. So this is a 4bt powered m715, nv4500, divorced np205, 14bff, d60, etc with these tires. Note when he stopped at first he had to go for 2nd, 1st was too low.
He is now about finished with a 1942 WC-53 - super cool ride.
I will get some underhood shots today. Lost all mine on the computer crash after I said "Format C:\"
