Dual tires are beneficial for fleets. They can increase load capacity and are ideal for hauling heavy loads over long periods. However, it’s important to make sure that dual tires match.

The two dual truck tires need to be the same size. If there is any variance, the smaller tire will have to work harder. This causes it to scrub along the pavement to keep up with the bigger tire.

If there is any height variance over ¼”, the tires are considered out of spec and will result in the larger tire carrying up to 600 lbs more than the smaller tire. This difference can lead to several problems, including:

  • Reduced tire life: Mismatched dual tires will wear unevenly, which can shorten the life of both tires.
  • Increased fuel consumption: Mismatched dual tires can cause the vehicle to drag, leading to increased fuel consumption.
  • Reduced safety: Mismatched dual tires can make the truck more difficult to control, increasing the risk of accidents.
  • Mechanical Strain on Vehicle: Mismatched dual tires can also cause mechanical strain on the vehicle. This can lead to increased wear and tear, requiring more frequent service calls.



One of the main reasons the current methods aren’t being used to properly measure dual tires is because the process tends to be cumbersome and time consuming. Some of these methods include using endless measuring tape, string gauge or a wooden straight edge.

Instead of using these methods, it has become more common to measure tread depth to determine if the tires match. This is typically done by using a tread depth gauge or by eyeing up the tires. Even if the tires have the same tread depth, there could still be differences in the tread, the height of the sidewall, or other places on the tire that affect its circumference, making measuring this way inaccurate.

Combatting the effects of mismatched dual tires can be simple.

Proper tire pressure and matching tread depth are important, but they will not guarantee that your tires are a perfect match. Our new tire height tool, The MATCHMAKER, was designed to quickly and effectively measure tires that are being paired together in a dual arrangement. The MATCHMAKER uses the radius of the tire to calculate its diameter, which allows operators to match tire height based on accurate measurements. This results in improved accuracy and reliability in the match-mounting process.

It can be used in the shop or the field with mounted tire and wheel assemblies on or off the vehicle. Using the MATCHMAKER to match your dual tires will help your fleet extend your tire tread wear and improve your fuel mileage. 

While making sure your dual tires match properly may seem like an extra step in your wheel-end maintenance program, it is crucial in helping your fleet save their tires and money. One service call to fix the potential damage caused from mismatched dual tires could potentially cost more than the preventative act of using the MATCHMAKER.
