The only thing you need when running a tire shop is a wheel balancer, which means you need weights. This is good BUT the double sided adhesive backing on it is all one piece. You have to cut them apart with a razor. :( Glue is good, I didn't have a single drop. I also wish they had weight in ounces and grams but that's getting a bit nitpicking. 4 stars because of the sticky backing in one piece.
