May be ok for air in tires. For anything other than these items, go to a place that knows how to fix things properly. After having my car completely misdiagnosed to a tune of $1000 I contacted corp office. When they know it's a complaint they take a message. Today day 5 and can't get anyone to call back. 4 calls to them. It's okay, credit card company is helping me but beware of Tireworks stores and their corp office. Not a good company to do business with. Update. Someone called me today. Took 5 days. Also spoke to two more people ripped off here. One for brakes who didn't need them and one for struts at a tune of $2k. This one was bad. She is a senior citizen who is also disabled. Channel 13 is going to know about this place
