The P Zero Race TLR SL-R sits at the top of Pirelli's road racing tire range, built around a simple priority: speed. Made in Italy at Pirelli's facility next to their global R&D headquarters, this is the lighter, faster sibling to the standard P Zero Race TLR, with construction choices that trade some durability for outright performance. If you're racing, time-trialing, or want your fast tire to actually be fast, this is the one Pirelli points to.

The headline technology is PAAS, Pirelli's Advanced Aerodynamic System. Developed through CFD analysis and wind-tunnel testing, the patent-pending profile creates a seamless transition between tire and rim on modern wide-rim wheels, keeping airflow attached longer and reducing flow separation. Pirelli calls the resulting effect "sailing," and the gains hold up as the tire wears — useful when you're a few thousand miles in and wondering whether your fast tire is still fast. Pair these with a modern hookless or hooked aero rim in the 25-30mm internal width range and the system works as designed.

LiteCore is Pirelli's lightest TLR casing, running 120 TPI for suppleness without giving up the rolling efficiency that makes a fast tire feel fast under power. The casing is what delivers road feel and comfort — the difference between a tire that transmits every bit of road chatter into your hands and one that smooths things out while still feeling connected to the surface. At 275 grams in the 28mm width, this is on the lighter end of what's available in a tubeless road race tire, and the weight savings come from the casing construction rather than thinning out the tread....
