Tread patterns that work across multiple surface types require compromise—fast-rolling center knobs sacrifice grip on loose terrain, while aggressive knobs everywhere add rolling resistance on hardpack. Challenge addresses this with the Getaway Pro Series TLR, spacing center knobs tightly enough for pavement efficiency while opening transition zones where sand and wet gravel demand tread contact. The 1.3mm center knobs maintain straight-line speed on hardpack sections, transitioning to 1.5mm shoulder knobs when cornering angles shift weight off-center.

SMARTplus rubber compound toughens the tread against cuts and abrasion that shorten tire life on mixed-surface rides. This gravel-specific formulation maintains edge sharpness longer than standard compounds as the tire wears through hundreds of miles on varied terrain. The compound balances durability with traction rather than optimizing purely for rolling resistance, which matters when grip on loose corners prevents sliding that costs more time than a few watts of drag.

The 260TPI Super Polyester casing flexes over sharp gravel and washboard surfaces that would telegraph harshly through stiffer constructions. Handmade assembly applies natural rubber and latex coatings to each casing layer before building the tire, avoiding the heat-setting that can stiffen vulcanized manufacturing. PPS2 puncture protection layers both sub-tread and sidewall zones into a single system, addressing flats from glass on the road surface and sidewall cuts from trailside vegetation or rock strikes....
