Triple M Tire offers high quality high tread passenger tires in all sizes. All of our high treads get checked by our experienced graders, the tread depth is then measured to ensure we are providing the best quality for our customers. All high treads then get tested for any weather cracking, bubbles, and small pin holes on our start of the art pressure testing machine. We inflat all tires up to 30 PSI during inspection, rotate and visually inspect the tire under high powered lights for any defects. We are able to air test all sizes from 13" up to 20".
