32″ X 2.2″ Indiana Pass TC Semi-Slick

Our ground-breaking semi-slick in the new 32″ size, inspired by Meaghan Hackinen’s win in the 2026 Tour Divide, the great bikepacking race from Canada to Mexico along the crest of the Rocky Mountains. Indiana Pass (11,958 feet/3,645 m) is the highest pass along the 2,700-mile route that Meaghan traversed in just over 14 days, setting a new FKT (Fastest Known Time) in the progress.

Where do you go from such an achievement? Meaghan is exploring every possibility to shave off further time off her record rides. She is testing the new 32″ wheel size, and she requested our ground-breaking semi-slick tires in that size. Will the greater inertia make the bike more stable and hence easier to ride over these long distances? At the same time, tall and strong racers, like Ted King and Brennan Wertz, are curious about the new wheel size. Will it improve how the bike reacts when they sprint out of the saddle and rock the bike from side to side? The only way to find out is to try! But none of these riders want to give up the speed, comfort and grip of their supple Rene Herse semi-slicks. That’s why we’ll offer their favorite tires in the 32″ size.

The Indiana Pass feature our innovative semi-slick tread: Instead of distinct zones with different patterns, the slick tread transitions seamlessly into the side knobs, for better and more predictable grip as the bike leans into corners. The first row of side knobs is anchored on the center tread to stiffen the knobs for superior traction under extreme power—important when you sprint or climb out of the saddle and rock the bike from side to side. The knobs are arranged with our proprietary noise cancelling technology, making this tire almost eerily quiet for a gravel tire.

The innovations don’t stop there: The radius of the tread is significantly larger than the radius of the casing—effectively creating a tire that corners like a much-wider tire. This innovation also allows us to make the center tread thin and supple for ultra-low rolling resistance, while the tall side knobs provide superb traction when the tire sinks into the surface.

The Indiana Pass tires are available with a choice of four casings:

The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse. The Extralight casing takes the performance, comfort and feel of your bike to an entirely new level. The Endurance casing is reinforced for extra sidewall protection and puncture resistance, while retaining the speed and comfort for which Rene Herse tires are famous. The Endurance Plus casing provides the ultimate in sidewall protection for extremely tough conditions.

The Indiana Pass is tubeless-compatible. For tubeless setup, we recommend Rene Herse Supple Sealant. When used with tubes, we recommend Rene Herse TPU tubes.
