Pirelli P Zero Race TLR vs Continental GP5000 S TR: Which Tubeless Tyre Should You Run in 2026?

Tyres are the cheapest, highest-impact upgrade on any triathlon bike — a fast, low-rolling-resistance tubeless tyre can save real watts over a 40km or 90km bike leg without touching your position or your budget the way an aero wheel does. The Pirelli P Zero Race TLR and the Continental GP5000 S TR are the two most recommended tubeless road tyres for serious triathletes right now, and we’ve reviewed both individually on this site. Here’s how they actually compare.

Key Specifications

  • Pirelli P Zero Race TLR (SmartEVO) — SmartEVO compound tuned for low rolling resistance without sacrificing wet-weather grip, SpeedCORE bead for easier tubeless fitting and a more supple ride than older wire-bead tubeless tyres, 700c fit.
  • Continental GP5000 S TR — BlackChili compound (Continental’s lowest-rolling-resistance, highest-grip compound), 320 tpi casing, Vectran Breaker puncture belt, approx. 265g, runs 70–90 psi tubeless for a 70kg rider on 25mm.

Rolling Resistance and Grip

Both compounds are built for the same job — low resistance without giving up wet-road grip — and both are widely regarded among the fastest tubeless tyres you can buy on the high street. We don’t have independently verified lab data putting the two side by side on this site, so treat any specific watt-for-watt claim you see elsewhere with caution. In practice, most riders won’t feel a meaningful difference between them on a training ride; the bigger factor is running either tyre tubeless with sealant rather than on an inner tube.

Durability

Continental publishes the clearer real-world durability picture: the GP5000 S TR rear tyre typically lasts 4,000–6,000km before the tread wears through, with the front lasting considerably longer. We don’t have an equivalent independently verified mileage figure for the P Zero Race TLR at the time of writing — if longevity matters more to you than marginal grip differences, that documented number is a point in Continental’s favour.

Price

At the time of writing, Tredz has the Pirelli P Zero Race TLR Classic from £54.99 (RRP £74.99) and the Continental GP5000 S TR from £59.95. Both prices are correct at time of writing and worth rechecking before you buy, since tyre pricing on both moves with stock and promotions.

Which Should You Buy?

If you want the cheaper, currently-discounted option and are happy fitting a well-regarded tyre without a long independently-verified mileage track record, the Pirelli P Zero Race TLR is the pick at its current Tredz price. If you’d rather run the tyre with the clearest documented durability and Continental’s long-standing reputation for consistent quality control, the GP5000 S TR is the safer long-term choice for triathletes doing high weekly training volume. Either way, buy a matching pair rather than mixing brands front and rear, and never debut a new tubeless tyre on race morning.

Buying Tips

  • Check your rim’s internal width against each manufacturer’s tubeless compatibility chart before buying, especially on narrow aero rims.
  • Budget for sealant and valves separately if your wheels didn’t come with a tubeless kit.
  • Run either tyre in training for several weeks before racing on it.
