Dual Tires Vs. Super Single Tires: Which Is Better?
Depending on your trucking application, one may be better than the other. Check out the advantages and disadvantages of dual tires and super single tires to make the right choice for your fleet.
Dual Tires
Dual tires have been used on multiple axle fleets for decades to keep frames stable and ensure safety in the event of tire failure.
Dual Tires Advantages:
- Dual tires are typically used for non-steering axles and are best for heavy-duty commercial fleets.
- Two tires on both sides on an axle can double your fleet’s load capacity and maintain stability.
- You’ll maintain drivability in the event of a flat as the other three wheels on an axle will compensate for the blown tire.
- Your operators can better maintain control of the fleet in the event of a flat while heading to a service station.
- Fuel economy is comparable to super single tires.
Dual Tires Disadvantages:
- Space between the dual tires must be maintained to prevent rubbing and lodged debris.
- Because of the necessary space, you cannot upsize duals on a fleet.
- An underinflated or flat dual will cause uneven wear on the other tires.
- Inner dual tires are often difficult to reach to monitor air pressure.
Super Single Tires
Super single tires often eliminate the disadvantages created by dual tires on a commercial fleet. They’re increasing popularity has led to improved design and functionality for specific applications.
Super Single Tires Advantages:
- Super single tires eliminate the effects of uneven pressure between tires on one side of an axle by switching to a single tire.
- This also eliminates hard-to-reach tire pressure monitoring.
- Super single tires have a more substantial contact patch than standard dual tires, which increases a fleet’s load capacity.
- Highway routes, bulk commodities, and higher mileage fleets are perfect applications for super single tires.
- Super single tires can improve vehicle performance and reduce fuel consumption and maintenance costs.
- Overall tire weight is reduced which could allow for extra freight.
Super Single Tires Disadvantages:
- Super single tires don’t have the built-in backup in the event of a flat tire.
- Operators cannot drive to a service station and will require roadside assistance, which can rack up repair costs.
- Super single tires can cause the load to shift during a failure. Operators can lose control of the rig, putting themselves and other drivers in danger.
