The alphanumeric code ’88H’ on a tire represents the load index and the speed rating. Specifically, ’88’ indicates the maximum weight the tire can support, while ‘H’ denotes the maximum speed the tire is certified to handle safely.
107T on a tire indicates a load index of 107 (carrying capacity of 975 kg or 2149 lbs) and a speed rating of T (maximum safe speed of 190 km/h or 118 mph). These markings are part of the tire’s service description, ensuring safe and appropriate usage for specific vehicles.
P235 is the beginning of a tire size code: ‘P’ stands for Passenger type, and ‘235’ indicates the tire’s section width in millimeters from sidewall to sidewall.
The marking ‘114S’ on a tire represents the load index and speed rating. The number ‘114’ indicates the maximum load capacity the tire can support, while the letter ‘S’ denotes the maximum speed the tire is certified to handle safely.
The three numbers on a tire sidewall indicate the tire’s width in millimeters, aspect ratio (sidewall height as a percentage of width), and rim diameter in inches. These markings are part of a standardized system that ensures proper fitment, vehicle safety, and performance.
The marking ’10 PR’ on a tire stands for ’10 Ply Rating,’ indicating the tire’s load-carrying capacity. It does not necessarily mean the tire has ten physical layers of fabric, but that it can support the same weight as a ten-ply tire.
The code ’93V’ on a tire indicates its load index (93) and speed rating (V). The load index 93 means the tire can carry up to 1,433 pounds (650 kg) per tire, and the speed rating V means the tire is certified for sustained speeds up to 149 mph (240 km/h).
EV compatible tires are specialized tires engineered to handle the unique demands of electric vehicles, including higher curb weights, instant torque, and the need for noise reduction. They feature reinforced structures and optimized tread compounds to balance longevity and efficiency.
XL on a tire stands for Extra Load, indicating it can carry a higher maximum load than a standard tire of the same size. It is also known as Reinforced (RF) and is marked on the sidewall to help drivers choose tires suitable for heavier vehicles or loads.
Tire rotation is the practice of moving each tire on a vehicle to a different position (e.g., front to back, side to side) at regular intervals. This procedure promotes even tread wear, extends tire lifespan, and maintains safe handling characteristics.
