Review on Homeon Wheels Tire Saver Ramps - Enhanced Design with Anti-Slip Pads for Flat Spot and Tire Flat Prevention - 4 Pack (Black) - Including Carrying Bag and T Level by Jason Lee

I bought this for a car project that I keep outside. In my experience, cars stored outdoors lose tire pressure much faster than cars stored indoors. I found a complete set of 4 at Revain cheap and took them. They are plastic but appear to be of good quality. I hope they avoid potholes. I've been running them for a few weeks now. It's too early to tell if they work or not. I will report. In the meantime I will continue to monitor tire pressure to keep the tires round.
