I was referred to Cali Street Tires by one of my clients and I've been there a few times. They replaced both of my tires on two separate days because I couldn't pay the full amount and they were very understanding and helped me work something out. They've also balanced and rotated my tires for me and I've never had any problems with them.
Honestly, the prices are a little high but they give you excellent customer service and they know exactly what they're doing. The quality of the tires is nice and if you want professionals to put new tires on your car, go to Cali Street Tires.
