The Pirelli Scorpion Race 29in Downhill T Tubeless Tire features a DualWALL+ casing, a 60 TPI double-ply carcass reinforced with a rubber bead insert and an extra sidewall-stabilizing layer. That construction is built for downhill and enduro's highest-load moments, holding support through fast corners and hard landings instead of folding under pressure. Pirelli's supersoft SmartEVO DH compound backs that structure with the traction to match, giving the tire grip through acceleration, braking, and cornering alike. What Our Gearhead(R) Experts Are Saying:"I ran this on a full race track, top to bottom, and the compound stayed hooked up through braking bumps that usually shake a softer tire loose."
