Tyre Pressure Information: WTB's tyre pressure recommendations have changed over time due to further developments in technology. Riders may always reference the markings on their tyres for allowed pressures ranges, but WTB calculate pressure recommendations based on an average rider weight of 160-180 lbs and suggest increasing the minimum recommended pressure by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tyre pressure marked on a tyre.Manufacturer's Part Number: W010-0842Buy WTB Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Resolute is the ultimate all-weather gravel tire for those who don't want to fuss with conditions-specific tires for every season. Small, square knobs deliver consistent bite into a variety of terrain, while the ample spaces between them prevent packing up when conditions become fun (a.k.a wet). Truly all-season in nature, the Resolute's 42mm width makes it a set-it-and-forget-it gravel tire for endlessly undulating roads through all varieties of weather.Usage: Gravel • CyclocrossCondiitons: Hardpack • Dirt • Gravel • Loose • WetKey Features:Consistent Square Knobs - There are numerous ways to increase the speed of a gravel tire, but consistently spaced knobs with substantial surface area is the best way to achieve it. Resolute excels in efficiency by staying on the surface of the terrain until pedaling or braking forces it to dig in.,Mud-Shedding Design - Widely spaced square knobs deliver consistent traction while shedding mud or clay with ease. Performs well in all conditions, which means there is no longer a need to swap tires based on the weather.,Supported Outer Knobs - Rows of outer knobs are connected by a supportive base that runs the entire circumference of the tire. Additional rubber at the knob bases allow them to dig in without the unsettling feeling of a knob folding while cornering. This make the Resolute one of the most confidently cornering gravel tires in our line.,Tubeless Compatible - TCS (Tubeless Compatible System) is WTB's standardized tubeless system. These tires feature a TCS tubeless casing, which nearly eliminates flats and allows lower tire pressures to improve traction and comfort over a traditional tube-type tire..SG2 Puncture ProtectionSG2 is our unique puncture protection technology that provides bead-to-bead coverage to ensure both the tread and sidewall are protected from slashes and punctures. The nylon fibers within SG2 feature a uniquely flat profile, which reduces the amount of rubber between fibers. Improving the fiber-to-rubber ratio increases puncture resistance, reduces weight and improves the overall liveliness of a tire. While SG2 is primarily a puncture protection layer, its tightly woven fibers also improve air retention to better maintain pressure between rides.
