You could guess this was coming. With the increase in the number of fat bikes running 27.5″ wheels and tires, it was only a matter of time until 45NRTH joined the party. As usual though, 45NRTH took their time in designing what they consider to be a superior take on the new standard, and if it’s anything like their other tires, it should be a great addition to the available options.

Starting with two of their popular tread patterns, the Vanhelga and Dillinger 4 are now supersized into 27.5″ tires. That means the Vanhelga will fill in as the more aggressive, all purpose tread while the Dillinger 4 is a studdable tire with large center paddles for loose and icy conditions.

Sized as a 27.5 x 4.0″ tire, both claim to have larger diameters than the current 27.5 x 4.0″ tires out there for more give to the tire’s casing. If you want the specifics, check out the Tire Measurement chart that 45NRTH put together – it’s an impressive resource for the crazy world of fat bike tire sizing. The two will be available in both 60 and 120 tpi casings, with tubeless ready beads. For the Dillinger 4, the two casings will have different studs – the 60 tpi will include steel-carbide studs, while the 120 tpi will include the higher end concave aluminum carbide studs for better grip.

Non-studded tires are available now, while studded tires will be available in October. Pricing starts at $90 for the 60 tpi Vanhelga, $115 for the 120 tpi Vanhelga, and $120 for the 120 tpi Dillinger 4 without studs, or $160 for the 60 tpi studded and $210 for the 120 tpi studded.

The tire measurement chart doesn’t have the new tires on it?

What are the odds that not-Bontrager comes out with a 27.5 x 4.5 or 5?

I can hope.
