NOTE: This 38 mm Schwalbe Pro One TLE was tested as a CX-Gravel tire at low air pressures. You can also find a test of the 25 mm Pro One TLE in the road bike section.
The Pro One TLE is Schwalbe's most high-end all-round road bike tire, and it's available in many sizes. We already tested both the 32 mm (read our review) and 34 mm (read our review) versions last year, and this time, we will look at the recently released 38 mm version that will be an excellent choice for gravel bikes and touring bikes that require the absolute fastest tire type.

Over the last few years, we've seen a trend towards bigger road bike tires, and most newly introduced road bike tires now include 32-622 sizes, and some even go up to the 35-622 size. It now looks like manufacturers are ready to go even bigger, and 38, and 40-mm versions of their fastest road tires are becoming available. Schwalbe has an excellent reputation regarding the availability of many sizes, and we're not surprised they're among the first to introduce a 38/40 mm road bike tire.
We've already given plenty of introduction of the Schwalbe Pro One as it's been around for a long time. We recommend reading the other Pro One articles on our website if you're interested in more information about the Pro One.

The CX/Gravel section is a multi tire size section, air pressures have been adjusted to the measured casing width. All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs. Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load. |

Conclusion
- Schwalbe Pro One TLE Addix 38
(100% is fastest - lightest - highest - strongest)
If you're looking for a 38/40 mm road bike tire, your choices are limited, and the Schwalbe Pro One TLE will probably be at the top of your list. The 38 mm version of the Pro One performs similarly to the 32 and 34 mm versions we tested last year. We see some subtle differences, like a thicker tread, which we see more often on the bigger versions of the same tire.
Our wet grip tests again show that the Schwalbe Pro One has a dual compound rubber with a harder compound in the middle and a softer compound along the edge. The result of this dual compound is that the overall wet grip is lower than most comparable tires due to the relatively low grip of the center compound, while the edge grip tests show decent results. The 38 mm version seems to grip a bit less than the 32 and 34 mm versions, and we think it's because the hard center part is a bit wider on this size.
We rate the 38 mm version higher than the 32 and 34 mm versions simply because it's one of the few road bike tires available in the 38 mm version. For a tire of this size, it is simply one of the fastest on the market.
