I don't know if I've ridden them enough to give accurate durability data. I can say they performed very well in the 8 inch snow I rode in over dirt roads. And I've never had to touch mud or snow with anything other than my gloved fingers and boots. They were incredibly easy to install. I didn't have to lie on my back or side. I didn't have to grab the steering wheel. I put them on in about 1 minute per wheel. They retreated in seconds. For the price, make sure you wash them promptly to keep them in good condition.
