I had a set on the rear and those things grip and dig like nothing I've ever seen, worked in my situation. If you do a search on you-tube you can find people that have put multiple sets on the rear tires. Also, the extender bars are great for anytime you get high centered, but can only be used on the rear tires (obviously). Also, make sure you don't run them through the rim where your valve stem is...you'll get a flat. I didn't do that, but the guy I borrowed them from said he learned that lesson the hard way.Buzz, I see the claws are sold 2 per set. Are 2 claws (1 set) on each rear or front wheels enough to get you out of deep snow or mud?
Do you like them better than chains, or just easier to put on
When you're in a pinch, they definitely are wayyyy easier to put on than chains. Seems like the only time I'm putting chains on is after I'm stuck, which is a huge PITA almost every time.
I'll not be without a set of these...
