Pirelli P Zero Race TLR Tyre Review: A Tubeless Upgrade for Triathlon Bikes

Tyres are one of the cheapest, highest-impact upgrades on any triathlon bike — a fast, low-rolling-resistance tubeless tyre can save you real watts over a 40km or 90km bike leg without touching your position or your wallet the way an aero wheel upgrade would. The Pirelli P Zero Race TLR SpeedCORE SmartEVO is one of the most talked-about road tubeless tyres of the last two seasons, and it’s currently discounted at Tredz.

Key Features

  • SmartEVO compound — Pirelli’s grip-and-rolling-resistance compound, tuned for low resistance without sacrificing wet-weather grip on the road sections of a triathlon bike leg.
  • SpeedCORE bead — a lighter, more supple bead structure designed for easier tubeless installation and a more comfortable ride than older wire-bead tubeless tyres.
  • Tubeless Ready (TLR) — runs sealant for puncture protection, letting you drop tyre pressure a few PSI for comfort and rolling efficiency without the pinch-flat risk of a tubed setup.
  • 700c fit — sized for standard road and triathlon-specific wheels; check your rim’s internal width against Pirelli’s compatibility chart before buying if you’re running a narrow aero rim.

Price and Where to Buy

Tredz currently has the Classic version from £54.99 (RRP £74.99), in stock and usually dispatched within 1-2 working days. That’s a meaningful discount on a tyre that regularly retails closer to full RRP elsewhere.

Buying Tips

  • Buy a pair, not a single tyre — matching front and rear compounds gives more predictable handling, especially descending in a race.
  • If you’re setting up tubeless for the first time, budget for sealant and valves separately if your wheels didn’t come with a tubeless kit.
  • Run these in training for a few weeks before race day — never debut new tyres, especially tubeless ones, on race morning.

Care and Maintenance

Top up sealant every 2-3 months, more often in hot weather when it dries out faster. Check tread depth and sidewall condition before every race, and rotate front-to-rear if you notice uneven wear, since rear tyres typically wear faster under triathlon riding positions.
