My 76 is currently sitting on a 4" SKyjacker lift with Extended shackles from the yr 2000 and nearly brand new 35x12.50 mud tires that were mounted in 2003. Seems a little sketchy to be running tires that are 22 yrs old. They sat outside on the 40 for the last 20yrs to the point of rotting off the valve stems. I soap'd up new stems and popped them in without taking the tires off. Everything is holding air just fine and they roll at 65 mph but I feel like I'm running on a ticking time bomb. I loved my 255/85R16 tires but would like to stick with as close to a 35" as possible. Any experience with something closer to a 35"x 10.50 or 11" range? Even when when current tires were new, she tended to wonder a little more than I like at freeway speed. I'm running an International Scout power steering that seems pretty solid. All new tie rod ends when I did the frame off last year.
