Semi-trucks, also known as 18-wheelers, are an integral part of the transportation industry. They are used to transport goods across long distances, and require tires that can endure the wear and tear of long-distance travel. So, what size tire does a semi-truck have?
Tires for semi-trucks come in a variety of sizes depending on the make and model of the vehicle. The most common size tire for these vehicles is 11R22.5 or 11R24.5.
This size refers to the overall diameter of the tire in inches (11″) and width (R22.5″ or R24.5″). These tires typically have a load rating of 10,000 – 14,000 pounds.
The tires on semi-trucks are also divided into two categories: steer tires and drive tires. Steer tires are typically mounted on the front axle of the vehicle and provide stability while driving. They tend to be narrower than drive tires, with sizes ranging from 8R19.5 to 11R22.
Drive tires are mounted on the rear axles of the truck and provide propulsion when driving. These tend to be much wider than steer tires, with sizes ranging from 11R22.5 to 12R24.5 or 13R25.
Conclusion:
In conclusion, semi-trucks require large and durable tires that can withstand long distances and varying loads while providing stability and propulsion when driving.5, with steer tires typically being narrower than drive tires.
