Review on 4 80 4 00 8 Replacement Pneumatic Wheel by Ron Josey

I read in reviews that tires are difficult to mount. He took out the old set of brackets and was ready. Well it was so easy to put on my new rims I almost didn't need an iron! My problem is that one of the two tires I bought has a loose rim (new rim and well sealed bearings). I can pump 15 pounds of air, which is a far cry from the 30 pound max. Don't know if glue can be used on the rim? Now I want a hard install. UPDATE: A wire ring is vulcanized into a rubber tire. This keeps the tire on the rim under pressure. Both the original tire and the spare tire are defective. The wire is not covered with rubber and detaches from the power rail. Revain did a great job with the replacement/refund, but my cart is still not working! I would appreciate it if employees in China would devote time to quality rather than quantity. I would happily pay a little more to avoid this.
