- Specialized Tracer TLR 40
(100% is best)
Specialized has recently revamped almost its entire tire lineup, and the do-it-all Tracer also received a huge update. The Tracer's tread pattern is as versatile as can be and should be a good choice for almost all gravel bike conditions except for those conditions where you need the absolute maximum amount of off-road grip. We can also see this tire working well when mixed front/rear with the Specialized Pathfinder or Terra TLR.
We can already tell you that the new Specialized gravel tires are completely different, with all the important aspects changed: casing, compound, and tread pattern. This is unsurprising since these tires now come from a different factory in another country. We already tested a similar construction Pathfinder TLR in both the 40 and 45 mm sizes, and weren't fully convinced the new construction was an improvement.
The Tracer TLR comes with a 60 TPI casing, and it's important to note a significant change when compared to the old Tracer Pro 2Bliss Ready: the BlackBelt anti-puncture strip has been removed. Removing the layer of Blackbelt looks to have resulted in quite a significant weight saving, as the specified weight of the 40 mm Tracer TLR is now 460 grams, while the old 42 mm Tracer Pro 2Bliss Ready came in at 525 grams.
The compound is Specialized's Gripton T5, the fastest version of their Gripton compound available today. The original Gripton compound was one of the best available at the time of its release, around 2016. While it was still competitive, the new Gripton T5, T7, and T9 compounds probably offer better specialized performance.
The tread pattern has also been revised, giving the Tracer TLR a much more modern look. Also new is that the standard sidewall color is now tan instead of black. As far as we can see, only the 700x45 size is available in either black or tan sidewall versions, while the 40 and 50 mm sizes are available only with tan sidewalls.
We've tested the 40 mm version of the new Tracer TLR and will compare it to the new 40 mm Pathfinder TLR (read our review) and a wide range of similar tires from competing brands.

| 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
- Specialized Tracer TLR 40
(100% is fastest - lightest - highest - strongest)
The Specialized Tracer TLR is an average-performing tire that ends up in the middle of the pack in most of our tests. The main weakness is the puncture resistance of both the tread and sidewalls, and we consider that an important aspect, especially given that Specialized dropped the BlackBelt anti-puncture layer on the new Tracer TLR. If you were used to the old Tracer Pro 2Bliss Ready, this can be a big deal.
When compared to the competition, we see many tires from other brands that perform better in our tests. We only recommend the Tracer TLR if you already own Specialized equipment and want to go all-in on Specialized.
