These guys have been very helpful. I started using them when I had low tire pressure, and when they added air (free of charge), they showed me that my tires (purchased in NJ) were losing tread and it was ripping in places. I needed new tires and wasn't aware. They were right though. We found our original warranty paperwork and they helped us get a credit towards the purchase of new tires. When the temperature dropped this week, so did my tire pressure and I stopped in again and they added air free of charge. I was rushing in between dropping kids off to school, but didn't want to continue on the road if my tires weren't safe. It was a 2 minute stop and I was back on the road - no hassle. Great customer service.
