Category Breakdown
Weight Savings
Super Single Tires winsSuper singles save approximately 1,000-1,500 lbs per truck compared to dual tires. For weight-sensitive loads, this translates directly to more payload capacity per trip — potentially $150-$300 more revenue per load.
Fuel Economy
Super Single Tires winsSuper singles have lower rolling resistance due to less rubber on the road, improving fuel economy by 2-4%. Over 120,000 miles per year, this saves $1,500-$3,000 in fuel.
Blowout Risk
Dual Tires winsA dual tire blowout on one tire leaves the paired tire to support the axle, allowing the driver to stop safely. A super single blowout leaves no backup — the truck is immediately compromised. This is the single biggest risk of super singles.
Tire Cost
Dual Tires winsSuper singles are more expensive per tire than individual duals, and you cannot rotate inners and outers. However, you buy 4 tires instead of 8 per drive axle, partially offsetting the per-tire premium.
Availability
Dual Tires winsIf a super single fails on the road, finding a replacement at a nearby tire shop is much harder than finding a standard dual tire. Duals are stocked everywhere. Super single road service can mean long wait times in rural areas.

Our Verdict
Dual tires win for most trucking operations due to the safety advantage of redundancy and universal availability. A flat tire should be an inconvenience, not a crisis, and duals provide that safety margin.
Super singles win for weight-critical operations (heavy commodities, steel, paper) where the 1,000+ lb weight savings translates directly to more revenue per load. In these applications, the additional payload revenue can justify the risk.
Conservative operators choose duals. Weight-optimized operations evaluate super singles carefully.
