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 Luis Blaschko

These tire protectors are very easy to fit and use on bare concrete. I ordered two sets due to the width of my sports car tires. I just connected them together and placed them right in front of the car's wheels. I carefully rolled the car towards them. No slips or anything like that. They match the tires well. Looks like they keep them in shape while the car is sitting in winter. The carry/storage bag is a plus. I get a level too, but I don't see the need for it. But a good extra to have around.
