The current Pirelli P Zero Race TLR is a high-performance tubeless road tyre built around the Italian brand’s SpeedCORE casing and SmartEVO compound. It is intended to sit in the useful space between an uncompromising race-day tyre and something durable enough to leave on the bike for fast everyday riding.
Independent testing supports the speed claim unusually well. In BikeRadar’s controlled rolling-resistance test, the P Zero Race TLR recorded 11.86 watts at 30km/h and finished as the most efficient tyre in its comparison. The same review praised its grip, low air leakage and ride quality, while noting that it is relatively heavy and can measure narrow with a rounded profile.

SpeedCORE is the important part of the current tyre
The current-generation Race TLR uses a thin airtight rubber layer containing aramid particles on the inside of its 120 TPI casing. Pirelli calls this SpeedCORE and says the construction improves flexibility, mechanical resistance and air retention compared with its previous tubeless casing.
The tread continues to use SmartEVO, Pirelli’s performance road compound. The combination is designed to reduce rolling resistance without turning the Race TLR into a fragile special-event tyre, and that balance is the main reason it remains relevant even with the faster P Zero Race TLR RS now sitting above it.
Rolling resistance is genuinely competitive
Tyre marketing is full of claims about speed, but the Race TLR has useful independent laboratory evidence behind it. BikeRadar measured 11.86W of rolling resistance at 30km/h in its group test, 0.22W ahead of the Schwalbe Pro One TLE and 4.82W ahead of the least efficient tyre in that particular comparison.
The differences between the fastest tyres were small, so the result should not be treated as proof that the Pirelli is always the quickest option in every width, pressure and road condition. It does show that SpeedCORE belongs in the front group of modern performance road casings rather than relying on feel alone.
Grip and ride quality broaden its appeal
Independent road testing has consistently been positive about grip and handling. BikeRadar described a fast, efficient ride with plenty of grip and relatively low tyre noise. That combination matters because a tyre used for normal road racing and fast training needs to work beyond a laboratory drum.
The Race TLR is not the lightest tyre in its category. A 28mm tyre is listed at 315g on Pirelli’s current UK specification, and the casing can produce a relatively rounded profile depending on rim width. Riders chasing minimum rotating weight have lighter choices, including Pirelli’s own RS version.
Tubeless setup and rim compatibility
BikeRadar found its test tyres straightforward to fit and particularly good at retaining air once sealant was installed. As ever with road tubeless, the exact experience depends on the rim, tape, valve and tyre combination rather than the tyre alone.
Pirelli permits hookless use on compatible 28mm-and-wider versions subject to the applicable ETRTO pressure limit, while 26mm and narrower versions should not be used hookless. Riders should follow the tyre and wheel manufacturer’s limits rather than assuming one pressure is suitable across every setup.
ProCyclingUK’s tubeless sealant comparison and maintenance guide covers the upkeep side, while the Dynaplug Racer Pro review looks at roadside repair once a hole is too large for sealant alone.
P Zero Race TLR versus the Race TLR RS
The newer Race TLR RS is Pirelli’s more race-specific option. It uses a lighter construction and SmartEVO2 compound to chase lower rolling resistance and weight. That does not make the standard Race TLR obsolete. The regular tyre remains the more obvious choice for riders who want high-end speed without paying for the most specialised version.
At current discounted prices the standard tyre is also substantially easier to justify. Tredz’s listing starts at £42.99, compared with an RRP around £79.99 for some variants. Exact pricing changes considerably with width and colour, so it is worth checking the required size rather than comparing headline prices alone.
Who should buy the P Zero Race TLR?
The standard Race TLR makes most sense for fast road riders who want one tyre for racing, summer training and quick group rides. Its laboratory efficiency is good enough for competition, but its construction is not as narrowly focused on race-day weight as the RS.
Riders prioritising winter mileage, maximum puncture protection or four-season wet-weather use should look towards a more protective tyre, including Pirelli’s 4S version. Anyone chasing the lightest and fastest Pirelli setup can instead move up to the Race TLR RS.
Pirelli P Zero Race TLR verdict
The strongest argument for the P Zero Race TLR is balance backed by evidence. It has tested extremely well for rolling resistance, independent reviewers rate its grip and ride quality highly, and SpeedCORE gives Pirelli a modern tubeless casing without pushing the standard tyre into the narrow role of a race-only product.
Its weight is ordinary rather than exceptional and tyre width can come up narrower than expected on some rims, so there are reasons to look elsewhere. At the current discounted Tredz pricing, however, it offers a strong combination of measured speed, tubeless practicality and high-performance road handling.
