These tires are perfect for our tires - we didn't have to tighten them much and they've weathered several Florida storms and stayed in there all along. and the winds were strong enough to make out a large tree somewhere in our yard. We've only had them a few months but they still look brand new; I think they will last a while. And since they weren't that expensive, I think if they last a few years they'll be more than worth it.
