The LTX has been on the market for quite some time now, but Michelin has given it a significant update. The truck and SUV tire now features interlocking siping to preserve rigidity in the blocks, the addition of silica for improved performance in wet weather, a new contact patch shape for longevity, and three-steel-belt construction. It's designed for reduced vibration and road noise. There are 38 P-metric and LT sizes in this line, for 15- to 20-inch wheels.
