LATERALLY BIASED SHOULDER ELEMENTS
The shoulder element design effectively conducts water evacuation away from the contact area while combating irregular or "heel - toe" wear.
OPTIMIZED PITCH SEQUENCE BY SIZE
The Discoverer H/T Plus varies the number of shoulder elements based on tire size, which reduces noise frequency, allowing a quiet ride.
TAPERED TREAD
This design feature puts deep tread in the center and slightly shallower tread in the shoulders. This puts more rubber down in the fastest wearing part of the tire, the center. The result is less weight and improved wet handling.
RIM PROTECTOR
A rubber rim protector extends beyond the rim flange and decreases the chance of rim damage that can occur if a tire / wheel assembly scuffs a curb.
OPTIMIZED TIRE PROFILE
The slightly rounded mold profile of the Discoverer H/T Plus balances wet traction and long tread life.
ALL-WEATHER TREAD
"See-through" grooves, wide, lateral traction slots and high sipe density provide excellent all-weather performance.
"CENTRAL CHANNEL GROOVES SUPPORTED BY TWO, WIDE CIRCUMFERENTIAL GROOVES
"Because contact pressure is greatest at the center of the footprint, it is important to evacuate water from this area efficiently to avoid hydroplaning. This is especially important in tires with wide treads, like sport truck sizes. The central channel grooves move water from the center of the tread to the two outer circumferential grooves for evacuation.
