All About Wide Base Tires: Single or Dual Options and Their Impact on Your Tasks
In the world of trucking, maintaining optimal performance is a constant pursuit. One area that has garnered attention is the use of Super Single Tires (SST). These tires, designed to replace traditional dual tires, offer several benefits but also come with their own set of considerations.
Firstly, SST are essential for super single tires, as they help ensure proper inflation and prevent safety issues. However, they are not a shortcut to better margins without changing the maintenance culture. Failure to maintain them properly can lead to problems, making it crucial to approach the decision with a fleet's maintenance culture and discipline in mind.
The fuel efficiency gains from SST are contingent on perfect alignment, spot-on inflation, and consistent driving conditions. In ideal scenarios, these tires can save around 300-400 pounds per axle compared to traditional dual tires, leading to increased payload and revenue per trip in tight-margin operations.
One of the key advantages of SST in trailer applications is their ability to make sense, especially for drop-and-hook or dedicated freight with consistent loads and routes. However, it's important to note that the decision to switch to SST should be made with a clear understanding of the fleet's maintenance requirements, as the availability of SST at truck stops can be an issue, especially in remote areas.
Converting from duals to SST requires changing wheels, possibly adjusting suspension specs, and ensuring axle ratings are compatible. This transition can be costly, as SST are more expensive per tire than traditional duals. Uneven wear can lead to full replacements instead of rotations, adding to the cost.
The ride quality and handling of SST can be subjective. While some drivers prefer the responsive feel and reduced fatigue, others complain about the increased road feel and vibration. It's a trade-off that drivers must consider.
It's also worth noting that SST do not inherently reduce blowout risk; they increase the impact of a blowout because you lose both support and stability. In the event of a blowout, the consequences can be catastrophic, affecting not just the tire but also the rim, fender, and nearby objects.
Some carriers opt not to run SST in winter conditions due to traction concerns in snow or ice. This is something to consider for fleets operating in cold climates.
Lastly, it's important to consider the resale value when deciding to switch to SST. These tires can negatively impact resale value for used buyers who aren't set up to maintain them.
In conclusion, the decision to switch to SST should be made like a business owner, not a brochure reader. On the side of the road, it won't be the ad that helps you; it'll be the discipline you had before the problem started. The largest manufacturers of SST suitable for trucks include major tire companies like Michelin, Bridgestone, Continental, Goodyear, and Pirelli, which produce wide, single tires designed to replace dual tires on truck axles. These tires offer benefits such as reduced rolling resistance and weight compared to twin tires but may have somewhat lower mileage and less redundancy in case of tire damage.
With proper maintenance and a clear understanding of the pros and cons, SST can be a valuable addition to a fleet's operations.
