What does 155R13LT tire mean?
2 Answers
155 represents the width of the tire's cross-section at its widest point in millimeters, R stands for radial construction, 13 is the rim diameter in inches, and LT indicates a light truck tire. Below is the relevant information: 1. Tires: Tires are rubber products. When rubber ages, it can harden on the surface, develop cracks, and lose elasticity. If tires are not replaced under these conditions, they may deform, bulge, or significantly increase the risk of a blowout. 2. Tire sizes: Tire sizes are printed on the sidewall and can be represented in two ways, such as 34*7 or 7.50-20. The former indicates a high-pressure tire, while the latter denotes a low-pressure tire. There are also many other markings, such as D for light vehicles, F for medium-sized vehicles, G for standard vehicles, and H, L, J for large luxury and high-performance vehicles. If an R is printed on the sidewall, such as 175R13, it means the tire is a radial tire with a width of 175mm, mounted on a wheel with a rim diameter of 330mm, and the word RADIAL is usually also engraved.
The set of numbers 155R13LT represents the tire size specifications. Let me briefly explain what they mean. 155 indicates that the tire width is 155 millimeters, approximately 15.5 centimeters wide. This is a relatively narrow width, commonly used on small vans. R13 means the rim diameter is 13 inches, and the 'R' also denotes a radial structure, which makes the tire more durable and improves heat dissipation. LT stands for Light Truck, meaning these tires are specifically designed for cargo vehicles with stronger load-bearing capacity and greater durability compared to regular passenger car tires. If you drive a microvan or small truck and frequently transport goods, this type of tire is ideal as it reduces the risk of blowouts and enhances safety. However, I should remind you that while narrow tires can save some fuel, they may have weaker grip during high-speed cornering, so drive carefully. Regularly checking tire pressure and wear is also crucial—don't wait until problems arise to replace them.
