What does 4S mean on a Pirelli P ZERO Race?

4S marks Pirelli’s all-season versions — Pirelli tags them “4 Season” and “All-season”. The P ZERO Race TLR 4S is tubeless ready, with the SmartNET Silica compound, which Pirelli rates as its best formulation for wet and chemical grip, on the SpeedCORE casing. The P ZERO Race 4S is the tube-type version, with the SmartEVO compound, the TechBELT casing and a deeper tread with more sipes to warm up and grip in low temperatures; Pirelli says its slightly thicker tread also adds mileage.

Tube type or TLR: which Pirelli road tyre should I choose?

TLR (tubeless ready) tyres can be set up tubeless: among the Pirelli road tyres we stock these are the P ZERO Race TLR SL-R, TLR RS, TLR and TLR 4S and the Cinturato EVO, and Pirelli marks them all hookless compatible. Tube-type tyres — the P ZERO Race RS, P ZERO Race, Race 4S, P ZERO Road and Cinturato Sport — are used with an inner tube, and the tyre itself can weigh less: the RS is a claimed 245 g in 700x30 against 310 g for the TLR RS. Pirelli recommends pairing the RS with its TPU SmarTUBE for a record system weight.

Can I use a Pirelli tube-type road tyre on a hookless rim?

Pirelli doesn’t mark its tube-type road tyres (P ZERO Race RS, P ZERO Race, Race 4S, P ZERO Road, Cinturato Sport) as hookless compatible: in its road catalogue the hookless badge appears only on tubeless-ready models. For a hookless rim, choose a TLR model such as the P ZERO Race TLR RS or the Cinturato EVO, and follow the pressure limits of Pirelli and your rim maker.

SmartEVO compound

Pirelli’s all-round road compound for racing and for long, high-intensity rides: a single compound built on three different polymers. Pirelli says it gives grip in any weather and very low rolling resistance, while standing up to high mileage and rougher road surfaces.

TechBELT casing

Pirelli’s tube-type road casing with a puncture-resistant nylon layer under the tread. Pirelli builds it at 120, 60 or 26 TPI, from racing (120 TPI) to daily commuting (26 TPI); the P ZERO tyres use the 120 TPI version.

Description

The P ZERO Race 4S is Pirelli’s all-season tube-type road tyre and the successor of the P ZERO Velo 4S. Its tread is deeper, with more sipes at higher lean angles to help the SmartEVO compound warm up and grip in low temperatures, while the slick centre keeps rolling resistance low; Pirelli says a slightly thicker tread also adds mileage. Choose it to ride through winter on inner tubes; the TLR 4S is Pirelli’s tubeless all-season option.
