Recently saw a post where someone stated emphatically, and incorrectly, that tire company ABC only covered their tires from date of a manufacture. So in an effort to set the record straight I decided to pull together some information. I am providing links and only a brief summary of the length of time a tire may be covered. As you see the time does vary and in many cases the clock doesn't start ticking until the date of sale BUT you will need to keep your proof or purchase.
I strongly suggest you read the warranty information for your brand and type of tire. In some cases the coverage for a Light Truck Radial, LTR is different than a Truck Bus Radial, TBR. DO NOT use what I say here as the final say or as the complete statement of warranty.
