When looking for truck tires for sale online, you are likely to come across numbers in their specs. The most common types of numbers you will find on tires are 11r22.5 and 11r24.5, both of which can say a lot about the tire’s performance for your vehicle. The code is typically etched onto every tire. 11r24.5 is the standard aspect ratio tire, where 11 refer to the nominal tread width, and the ‘R’ pertains to the radial design. 24.5 pertain to the diameter of the tire in inches. By knowing this information, you should be able to pick the right tires that will make your truck run smoothly and safely. Likewise, knowing the difference between 11r22.5 and 11r24.5 will help you in your buying decision.

You can refer to these numbers to determine the size of the tire, maximum single load capacity, and inflation pressure, too. The maximum single load of 11R22.5 tires is 6175 lbs, and their inflation pressure is 105 psi. 11r24.5 tires can handle a maximum single load of 6610 lbs, and their inflation pressure is 105 psi. You will need to check the ply rating of these tires, too, so you can determine the number of layers of cotton or nylon plies, which can help you determine their durability and level of resistance to wear and tear. 11R22.5 and 11r24.5 tires for trucks are typically rated 12 to 16 ply, and these ratings have corresponding letters (F, G, and H) to indicate load range.

Load range pertains to the tire’s maximum load resistance, and it will vary by inflation pressure and tire size. Larger tires are capable of holding more hair, thus, they are typically rated for higher loads. A given tire size with a higher air pressure will mean a higher-rated load. H load (16 ply) 11r22.5 and 11r24.5 tires have an inflation pressure of 120 psi and a maximum single load of 6610 lbs and 7160 lbs respectively.
