What Size Tire Is on a Semi-Truck?

Semi-trucks are some of the most imposing vehicles on the road. They can weigh up to 80,000 lbs and span up to 53 feet in length. But have you ever wondered what size tires are equipped on these behemoths?

The answer is that semi-truck tires can vary in size depending on their application and other factors such as road conditions, cargo weight, and terrain. However, the standard tire size for a semi-truck is 11R22.5. This tire size is also referred to as an 11R24.5 or 11R25.

The “11” in this tire size refers to the wheel diameter which is 22.5 or 24.5 or 25 inches across (the R stands for radial). This wheel diameter is necessary for semi-trucks because it provides better stability while carrying heavy loads over long distances.

In addition to the wheel diameter, this tire size has a tread width of 8 inches and a load capacity of up to 7500 lbs per tire when inflated to its maximum pressure of 110 psi.

Semi-trucks are outfitted with 11R22.5, 11R24.5, or 11R25 tires, which have an 8 inch tread width and are capable of supporting up to 7500 lbs each at 110 psi of air pressure. These tires provide better stability than smaller wheels while carrying heavy loads over long distances.

In conclusion, the standard tire size for semi-trucks is 11R22.5 or 11R25 which helps ensure they can carry their heavy loads safely and efficiently over long distances.
