FAQ

How is the 4S different from the standard P Zero Race TLR?: The 4S uses SmartNET Silica compound, formulated for superior wet and cold-weather grip, while the standard P Zero Race TLR uses SmartEVO Compound tuned for dry-condition race performance and pure rolling resistance. Choose the 4S when conditions are wet, cold, or mixed; choose the standard Race TLR for warm, dry race day performance.

Is the 4S durable enough for daily training?: Yes. The thicker tread and SmartNET Silica compound add mileage compared to a pure race tire, making the 4S a viable training and racing option year-round. It is designed for riders who want the same tire on the bike for hard winter intervals and spring race day.

What is SmartNET Silica?: SmartNET Silica is Pirelli's elongated silica molecule formulation, engineered for superior chemical grip in wet and cold conditions. It reduces heating and increases elasticity for consistent performance in rain, on cold pavement, and on variable road surfaces where standard race compounds lose grip.

Best For

Road racers and serious training riders in wet, cold, or unpredictable climates who refuse to switch to a winter tire and want full race performance year-round. Ideal for Pacific Northwest cyclists, four-season racers, and riders who train hard through the off-season.
