Body parts welded together.
Look behind your front tires and you'll see a pinch weld that gets artistically pounded over to fit bigger tires after a lift. I think this is "cowcatcher's" area of concern.
I keep a set of cable chains in my jeep and only used them to move a trailer into it's winter parking spot. All chain types need snugging up after a few turns of the wheels before the work begins or they can fling outwards from the axle and destroy stuff. Old chain style chains have the most mass and reach out inches from the tires. The rubber bands aren't enough to take up the slack when the tires spin. They need to be set up properly on both sides of the tire to work well.
Chains have helped me out a lot over the years. Happy to put them on to keep out of trouble. I always have them in the winter and hardly ever need them.
Thank you very much!
I stopped relying on those rubber band thingies years ago, and threw them away.
For a while, I used rope. Woven in a star pattern, stretched tight with trucker's hitches. etc. Then tightened again after about a 1/4 mile.
Now, I use cheapo ratchet straps in the same way. Shortening the long part of the strap, by quite a bit. (Cut it off so it doesn't get tangled.) Still stop after about a 1/4 mile and tighten everything. Sometimes twice.
And never go very fast at all. If I am using the chains, then conditions are bad enough to go as slow as possible, anyway.
I also add the screw type 'add a link', to ensure that no potential 'loose end' can work it's way loose to cause the kind of problems discussed here. I'd rather spend the extra time and trouble getting everything battened down tight, than to have to deal with the problems caused by loose chains.
