What is the difference between LT and C on tires?
3 Answers
The difference between LT and C on tires lies in their meanings. LT stands for Light Truck, indicating tires for light-duty trucks, while C is a speed symbol representing a maximum speed of 60 km/h. Below is more information about tires: 1. Functions of tires: (1) Tires ensure good ride comfort and smooth driving for vehicles. (2) Tires are crucial for the safety of drivers and passengers, playing a vital role in vehicle operation. 2. Tire selection: (1) For durability and versatility, consider Pirelli STR, a semi-urban, semi-off-road SUV tire suitable for various road conditions. (2) For handling performance, Bridgestone HP-SPORT is a good choice, being a sporty urban SUV tire. (3) For comfort, Continental CCC-UHP is recommended, as it is a comfort-oriented SUV tire.
Having driven trucks for over a decade, the main differences between LT and C tires lie in load capacity and construction. LT stands for Light Truck tires, featuring thicker sidewalls for durability to withstand heavy cargo vibrations. C denotes Commercial tires, commonly used in vans, offering slightly lower load capacity but at a more affordable price. For long-distance deliveries, I always use LT tires because their dual-ply construction prevents deformation under heavy loads and resists bulging on rough roads. C tires risk sidewall cracks when overloaded on long hauls. Tire selection depends on vehicle usage: pickups or frequent cargo carriers must use LT tires for safety; for regular passenger/cargo dual-purpose vehicles with light loads, C tires suffice.
When repairing cars, we often encounter owners asking about LT and C tires. Simply put, LT tires are heavy-duty types with reinforced sidewalls and deeper tread patterns. C tires are suitable for light cargo transportation, such as vehicles like the Wuling Hongguang. When actually replacing tires, pay attention to the different air pressure standards—LT tires require higher pressure to support weight. Last week, a van owner installed C tires to save money, resulting in tire deformation and air leakage when fully loaded. It is recommended to choose tires based on the tire pressure label on the door. The load indexes of LT and C tires differ significantly, so never mix them.
