Macro reinforces the notion that XC shouldnt be categorized by rigid posts and pinner tires. XC is growing faster by the day and Macro is here to exceed its expectations. Minimal, fast-rolling tread wraps over a wide casing to increase traction and confidence without added knob weight. Minimal tread overhang also reduces weight while a round tire profile provides smooth cornering on hardpack surfaces.

Macro is here to go faster.

Light as a Feather
The true 2.4 tire measures 62mm ( on an i30 rim) and weighs a scant 732g (120tpi black with SG protection). Cross-country racers want a Goldilocks mix of characteristics in their gear: speed without sketchiness, suppleness without delicacy, and tank-like grip without tank-like weight. For tires, its often been a matter of sacrificing one characteristic for another. Not anymore. The new WTB Macro 2.4 tire shatters that trend. It rolls fast, digs into the turns with precision, and deflects even the sharpest rocks thanks to its SG puncture protection.

Puncture Protection Galore
Part of the secret sauce is WTBs SG puncture protection, made of a rubberized nylon fabric that protects the sidewalls without compromising suppleness. The use of flat fibers in the SG barrier reduces weight compared to traditional round fibers and allows WTB to tune the ride characteristics even further.

Short, Efficient Knobs
Macros centerline is made up of small, tightly spaced knobs that pack a punch, delivering unmatched speed and braking traction. When you lean into a turn, the wider spacing and raised outer knobs provide steadfast grip when you need it most. Pair this dynamic tread with a wide, rounded profile and the ability to run lower air pressures, and you get an incredibly capable tire that delivers a perfectly smooth transition as you pitch in and rail through turns.

TCS Tubeless Ready
TCS (Tubeless Compatible System) is WTB’s standardized tubeless system. These tires feature a TCS tubeless ready casing, which nearly eliminates flats and allows lower tire pressures to improve traction and comfort over a traditional tube-type tire.

TriTec Compound
TriTec blends three distinct rubber compounds to provide different levels of traction, support and durability based on their placement within the tread. High durometer rubber provides a foundation for the entire tread pattern and even extends slightly into the base of each knob to provide additional support below the softer compounds used in the remainder of each knob. Center knobs feature a medium durometer compound to provide traction and durability without sacrificing rolling efficiency, while outer knobs feature the softest compound for maximum grip and slow rebound characteristics.

TCS Light Casing
TCS Light tires feature one layer of casing to minimize rotational weight while simultaneously increasing the overall liveliness of a tire. Using a single layer of casing results in a gram-conscious tire that better conforms to the trail and increases traction without the need for excessive knob heights that would reduce efficiency. Many of our TCS Light mountain tires feature Slash Guard technology, which provides a protective nylon insert spanning the entire sidewall to provide extra puncture protection without the weight of a dual ply casing.

SG Puncture Protection
WTBs SG tires start at the material level, specifically formulated for superior sidewall protection and increased air retention in high-pressure tires.

Sidewall Protection: The extra layer defends most exposed areas of the tire and improves air retention for high-pressure tires.

ZERO Plastic Packaging
All new WTB tires are packaged using 100% recycled materials and zero plastic. Our engineers and marketing team are constantly working towards reducing the amount of packaging our products requiring, while still providing you with the necessary information to make an informed purchasing decision. It’s no small task, but minimizing the total amount of packaging has become an integral part of product development.

This results in simplistic packaging using more recycled materials and less zip ties. In the next few years, we’re working to ensure 100% of WTB packaging goes in the recycling bins.
