Truck Tires

Purchasing truck tires is a bit different than purchasing car tires. Truck tires and SUV tires typically require a higher load capacity than other tires. The load capacity of truck tires is determined by the volume of air that is inside the tire, and the pressure of the air. Truck tires are also differentiated by the application that you have for them, either on highway or off highway (off road) or on and off highway (all terrain). Most tires that are manufactured for trucks will have a tire size that begins with the letters “LT”, which stands for “light truck”. No one type of truck tires is right for all trucks.

Ever wondered what all the letters and numbers on the sidewall of truck tires mean? So what is the difference between a 205/55R1688 V XGT V and a 225/45ZR17 90W? Other than one tire being produced by Michelin and the other by Pirelli and that they are performance rated tires, the differences are subtle but important. The numbers “205” refer to the width of the tire, as measured in millimeters, while the numbers “55” refers to the percentage of height of the sidewall. The letter “R” lets the buyer know that the truck tires feature radial construction. The numbers “16” let’s you know diameter of the wheel that the tires fit. The number “88” is a numerical code that is associated with the load that the tire can hold. The tire speed rating “V” lets you know that the tires are rated for speed up to 149 miles per hour. And finally, the code “XGT V” is the manufacturer’s code that has been assigned to the tire design.

Now that you recognize some of the many features that go into truck tires, you likely have a better appreciation for the importance of choosing the right one!
