As a hesitant automotive buyer I wasn't sure if the MOLIAN weatherproof protectors would truly DO the job. But after testing them out, I'm happy to report that they exceeded my expectations. These protectors fit snugly on my tires and have held up well in various weather conditions .The best part is that they are universal in diameter, so I dont have to worry about buying different sizes for each vehicle. The only downside is that they can be a bit tricky to install at first. Overall, I highly recommend these weatherproof protectors for anyone in need of tire protection..
