I am new to zuks, just picked up a very used beater and I am in the process of building it back up. Right now it is an 88 with a decent amount of body damage but it runs pretty well. The engine smokes some but I plan on rebuilding that early next year. Right now i have flipped the axles and installed custom shackles and small 3/4" blocks. My tires are bald and I found a great deal on used 33" BFG mud terrains. I can pick up all 4 with very decent tread for $100. I am afraid that without gears the larger tires will take thier toll on my clutch and tranny. So my question is does anyone run 33" tires on the stock gears and am I asking for trouble by doing this? I dont rock craw much, usually just trail riding, hillclimbs and mud running. I Would go with some thing like a 31" but these tires are just so cheap I really want to jump on it. This is strickly a trail beater and I dont want to spend anymore cash on it than I have to. Thanks in advance for the help
