Wide-base tire
A single wide tire that replaces a dual assembly per wheel end, also called a super single. Requires a wider wheel, has a different load rating structure, and changes spare-tire logistics.
Wide-base tires are not interchangeable with standard dual setups. Confirm wheel compatibility, load rating, and carrier policy before converting any axle.
Real-World Use
A fleet evaluating fuel efficiency considers wide-base singles for trailer axles, then checks load rating, wheel inventory, spare logistics, and fleet policy before committing.
