Terrible product. The bars got stuck on all 4 tires after a month. One came loose after using the vise. Another broke a sensor in the tire and ended up costing me $100 to replace. The other two are glued and I'm afraid to remove them due to damage to the sensors. I take them off when it's really necessary. In the meantime I'll spray them just in case wd. A very cheap item that costs more money in damage than the item is even worth.
