The TPU tube specific Pirelli P ZERO Race RS goes up against twelve other tubeless road bike tires in our group test – including its sibling, the P ZERO Race TLR RS. At first glance, the two models look almost identical, but the real differences go beyond just the concept. While the P ZERO Race TLR RS uses a tubeless setup, the Race RS takes a different approach with a classic tube-based construction. Pirelli’s goal? To deliver a similar level of performance while significantly cutting weight. And the numbers speak for themselves: the combination of the Race RS and Pirelli’s own SmartTube TPU inner tube weighs in at just 289 g – lighter than most tubeless tires, even before adding sealant.
Tube for the Win! – The Pirelli P ZERO Zero Race RS in Our 2025 Road Tire Test
When accelerating, the Pirelli P ZERO Race RS feels decent but not especially punchy. At higher speeds, it rolls efficiently – or at least that’s how it feels on the road. However, the lab tells a different story. With a rolling resistance of 16.6 watts, it’s the least efficient of all the tires on test. Slower even then MAXXIS High Road Gen 3 all-rounder and outpaced by the TLR version of the Pirelli by a full 4.6 watts. One possible reason is the Pirelli SmartTube, which isn’t the fastest TPU tube on the market. Pirelli claim their new SmartTube RS will significantly improve efficiency, but it wasn’t yet available during our test. Regarding grip, the Race RS performs admirably on both tarmac and light gravel. It doesn’t offer quite the same margin of safety as the TLR version, though the handling is impressively sharp and precise, offering a sportier feel than its tubeless sibling and revealing no hint of nervousness. Measuring 30.6 mm wide on our test rim, it’s slightly skinnier than the P ZERO Race TLR RS and comes closer to its stated width of 30 mm.
In terms of compliance, the P ZERO RS sits mid-pack. It’s noticeably more forgiving than the MAXXIS High Road Gen 3, though not quite as plush as the Michelin or Pirelli’s own TLR version. It absorbs minor road chatter well but feels firm and direct over rough cobbles. It grips moderately well on loose gravel, though damping drops off significantly on chunkier surfaces. Overall, though, it still offers a stable and confident ride. Mounting the tire is relatively straightforward, albeit with some effort. Still, the tube setup means no faffing about with sealant, which is a big plus for many riders. While most of the tires on test are easy to install, a tube is still the simplest option for many. Puncture protection is a mixed bag: while the tire performs well in terms of resistance to cuts and punctures, its pinch-flat protection is the weakest of the test field.

Conclusion on the Pirelli P ZERO Race RS
With the P ZERO Race RS, Pirelli offer an intriguing option for riders who want a modern setup without going tubeless. The tire stands out with its low weight, precise handling and excellent grip. However, this approach comes at the cost of efficiency and results in middling puncture protection. That may be perfectly adequate for most scenarios, though the P ZERO Race RS struggles to keep up with the performance focused competition. Still, it remains an appealing choice as a lightweight and hassle-free race setup, especially with the potentially improved performance of a faster TPU tube.
