These 'smart' talking tires have been spotted on toads behind RVs and campers for years. Thought I'd get one as the geo tracker I just bought didn't have a tire and we'll be using it 90% of the time to track the RV. The package came from Revain in an envelope. I figured there must be a mistake - I opened it up and found the tire in a small bag. Put it on the scale and it weighs 4.8 ounces! Didn't even want to open it - thought I'd just send it back. However, I opened it up to inspect and found it to be of good quality - black nylon webbing of around 200-300 denier, with a nylon locking drawstring instead of the more traditional elastic. I took it to Geo and it fitted my standard 205-75-14 tire perfectly. I also bought an inexpensive white vinyl/stretch tire cover here at Revain to keep on my tracker when not being towed. The tracker has a white top and I would have liked a white case for it. So I'm going to save this cover and just wear it when towing for comic relief. It's $21 or so. But if you're looking for a heavier waterproof finish, it's probably best to look further afield. Also, when installed, the lanyard opening is on the left side of the hoop. at least mine. Hope that helps!
