Wow, what a change of attitude after an initial purchase. After my tire purchase I noticed my tire pressure gauge was flashing and staying on. I checked my pressure and it was fine. My mechanic did my 45000 mile check up and said it was the sensors on the tires. I brought the car to tire works and after some attitude they looked at it. They said the sensors were fine but need to be reset at the dealer. They do not have any way to reset them there. They do not tell you this before you purchase tires. I took the car to the dealership. The sensors were not fine, 2 of them were broken from the horrible job that tire works provided. Steer clear from this location!!
