- Maxxis High Road 25
(100% is best)
If you're searching for the best road bike tire Maxxis currently has to offer, the High Road is the tire you're looking for. Maxxis calls the High Road "our flagship tire for elite racers who demand the best equipment" which leaves no question marks to us. The High Road is available in both a tube-type and tubeless-ready version. This is a test of the tube-type version and will be compared to tires like the Conti Grand Prix 5000 (read review), Michelin Power Competition (read review), Vittoria Corsa (read review).
The High Road features the latest HYPR compound from Maxxis. Maxxis claims the HYPR compound decreases rolling resistance by 16% while at the same time increasing wet grip by 23% when compared to their previous compounds. They also claim these improvements had no negative impact on the durability of the HYPR compound.
The tube-type version comes with a 120 TPI casing while the tubeless-ready version even comes with a 170TPI casing. Both versions of the High Road come with a K2 anti-puncture strip under the tread which they claim provides better puncture protection than standard Kevlar or Vectran. Both the tube-type and tubeless-ready versions are currently only available in the 25-622 size.

| The Road Bike 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
- Maxxis High Road 25
(100% is best)
The Maxxis High Road is a fast-rolling tire but comes a bit short to challenge the top performing tires in the all-round category. It does offer a slightly better puncture resistance of the tread area when compared to the direct competition. Another positive is a very low weight for the puncture resistance and air volume it offers.
We rate the High Road 4 out of 5 mostly because rolling resistance is the dominant ranking factor on our site. We feel the High Road is an excellent choice if you're looking for an all-round tire and you don't need those last few watts to be competitive. If wet grip and durability turn out to be better than competing tires, the High Road can be an excellent tire.
