Tire Spreaders

I work in at a dealership and they ordered this tire spreader. I in fact assembled it, not difficult to figure out because you have to due to the ridiculous assembly instructions, as time went on and customers would arrive with tire repairs needed, all techs eventually gave this a try. Not 1 out of 15 techs that used this JUNK do anymore. We actually threw it out! You cannot adjust it much, it doesn't work AT ALL for low profile tires, and the hooks are too long to spread larger truck tires. I had never got a tire repair to go easily with this piece of scrap metal. DO NOT BUY!!!
