This is my first time buying wheel chokes and these chokes are a joke. I think that's what you get for $5 or $6. It is made of lightweight plastic and the wind can easily blow right under the tires. I used my electric blower to scrape off the brake dust and it blew it right under the tire. It's thin so you can't squeeze it between the tires. has little to no weight, it can just slide off when your car is moving. Don't waste $5 or $6 on that plastic junk and buy a sold heavier choke.
