The rope is short but can be wrapped around a tire - front and back. They are not designed to drive through a vehicle to get a left and right wheel. Yes, they are heavy too. I like this as they are unlikely to move accidentally. They're a bit small, but more than adequate for stamping car tires. They fit perfectly under the back seat in my pickup truck. They seem pretty durable. The ones I bought I will probably pass on to my kids one day.
