The Michelin LTX A/S is a light truck tire designed with MaxTouch Construction™ augments traction and uniformly distributes the power of braking, cornering and acceleration that gives extended wear. It has superior fuel efficiency and less carbon emission from the engine due to its Fuel-efficient Energy Saver Construction™. It also provides sturdiness and toughness to handle loads due to its steel belts.
These are some pretty damn good tires. I have had Michelin tires on my Tundra for the last 6 years. They run about 55k miles before I have to replace them. Smoother than the original Bridgestones that came withe truck. Do yourself some good and get these tires.
