Is the P Zero Race TLR 4S Built for All-Season Racing?

The Pirelli P Zero Race TLR 4S is Pirelli's year-round tubeless race tire, engineered to maintain race-caliber performance in all weather rather than just on dry summer roads. The standout technology here is the SmartNET Silica compound, which uses the natural anisotropic orientation of silica rod molecules to reduce internal heating while increasing elasticity, minimizing energy dissipation and delivering high rolling efficiency. The wide surface area of those silica molecules enhances their natural water affinity, translating to confident handling and grip on wet pavement where other race tires start to feel vague.

The SpeedCore design adds an aramid band within the tire's rubber layer, reinforcing the casing structure while retaining a supple feel for minimal rolling resistance and maximum grip across seasons. A 120tpi nylon casing completes the package with added puncture protection and overall security under race-pace loads. Available in 700 x 28, 700 x 30, and 700 x 32, the P Zero Race TLR 4S suits road racers and performance cyclists who train and compete year-round without wanting to step down in tire quality when the temperatures drop.
