Horizons Unlimited - The HUBB - Airhawk or sheepskin

I have had 2 airhawks and I CANNOT recommend them. They work great, at least on the street. If you get into some dirt I'm not sure how well it will stay put. The problem is in the rubber compounds they use. It just starts to break down, even when not exposed to sunlight. I thought I just got a bad one so I got another after my first one started leaking and was unrepairable. The 2nd one did the same I actually spoke to some guy fairly high up in the manufacturing side of the business after writing a letter telling them to change their compounds. I mean seriously, I have tire tubes that last 10 times as long as an Airhawk. The company rep offered to give me a discount on a 3rd Airhawk, and said they actually have changed the compounds. I just don't want to be their beta tester on my dime anymore.
I suggest you go another route.
