This specific tire model features a BIASED ply construction.
Due to the acquisition by Carlstar Tires, Carlisle tires are now manufactured under the Carlstar banner. For this reason, some Carlisle tires might come with the Carlstar brand name stamped on their sidewalls.
Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
