tire clearance ,mud run help!!!!!

[CUCVinterceptor]

so im running a set of 34 x 12.50 tires(1986 m100 in our mud run with no lift or trimmed fenders. i have to make two left turns and thats it, anyone think ill rub and rip out inner fenders or even worse, peel back a qaurter panel. also should i run in 4 hi or low w/ the 4:56 gears in it.

need some advice please!!

4 high should do it, because the diesels dont rev as high as the gas engines

4high will be better for mud to keep the wheel speed up. just dont turn the wheels all the way to lock and you will be fine on the fenders.

I, myself, prefer low range in 2nd gear.
