Chris's46 /515 On rubber have on 8.25x20's truck is happiest at about 48 mph will do 55 but kinda beaten it up a little. Have a way to overdrive it but think it will be too much,could try it in low axle I guess. Now you understand it is a pickup 51 6400 98 inch wheelbase truck done at home by me. 10,000 miles since 2018 best pickup ever out of about 30 in 50 years.
