Before switching to wide-base tires: what changes
Wide-base tires, also called wide-base singles or super singles, are commercial truck tires bought to replace a dual pair with one wider tire on each wheel end. Wide-base tires come in sizes such as 445/50R22.5 and 455/55R22.5 and fit the drive axles of tractors and the axles of semi-trailers.
Wheels to buy with wide-base tires
Wide-base tires mount on 22.5 x 14.00 wheels with a specific outset, commonly 2 inches, which keeps the tire centered under the hub and the track width close to a dual setup. Switching from duals to wide-base tires means buying new wheels with the tires; dual wheels do not accept wide-base tires.
Weight and fuel savings when buying wide-base tires
Each wide-base tire and wheel weighs less than the dual tires and wheels it replaces, which adds payload capacity on weight-limited loads. Wide-base tires also have lower rolling resistance than a dual pair, which lowers fuel use on long highway runs and pays back part of the switch.
Trade-off to weigh before buying wide-base tires
A wide-base tire has no dual partner, so a puncture or blowout leaves no second tire carrying that wheel end. Fleets buying wide-base tires pair the purchase with tire pressure monitoring and roadside service coverage.
Buying wide-base tires for some axles only
A tractor-trailer can run wide-base tires on some axles and duals on others, such as wide-base tires on the drive axles and duals on the trailer. Each axle is bought all wide-base or all dual, never one of each on the same axle.
State weight rules to check before buying
Some states set axle weight limits by tire width, which can affect wide-base tires on heavy loads. Check the axle weight rules on your routes before buying wide-base tires for a fleet.
Choosing wide-base tires for drive or trailer axles
Drive-axle wide-base tires use lug treads for traction under torque; trailer-axle wide-base tires use rib treads for low rolling resistance and scrub resistance. Wide-base tires are ordered by axle, like the dual tires they replace.
