Ok, my driving experience dates back before radial tires were available. I have followed Jeep CJ's with the big fat tires on the highway at 55 mph and noticed they have a tendency to wander quite a bit between the lines. I see some of you are planning on running 34 & 36 inchers at 70 mph. I'm just wondering how the new jumbo tires are handling at these speeds, what you guys are currently running them on, and how they handle compared to a standard 15 or 16 inch tire on both wet and dry roads. I have had the impression that these tires were designed more for the off roader than an interstate cruiser. Your thoughts and opinions?
