s sawzall and a hammer. D30(s), how bout ya give him a break Deft, he probably goes wheelin when he's invited. What rear axle? a d35, 8.25 chryco, d44? You will be told not to run massive tires with the d30, or 35. I say carry lots of tools, parts, beer and party favors, so when you break it you have plenty of help. OR, upgrade your axles before shucking out cash for the tires. Get the axles first, then the tires. Run cheap tires, and use the cash to get axles. that way you don't fall into the I would upgrade the axles, but I keep havin to repair the old ones. You can find cheap tires, and still wheel, it's the axles that will hold you back. Put the horse in front of the cart, and it works better. By the way the bfg ats will get you as far as you need on the d30/35 combo. Is the chain on the bumper to lock it to a bike rack?
