Mountain bike tyres have evolved dramatically over the past decade. Compounds have become grippier, casings have become stronger and tread patterns have become increasingly specialised for every trail condition imaginable.

But one area of tyre design has remained largely unchanged: the way the tyre casing itself is constructed.

That's where RAD CORE technology comes in.

Developed through a collaboration between Nutrak and Vee Tyre Co., the new RAD CORE range introduces radial tyre construction to mountain biking, delivering increased grip, improved comfort and reduced rolling resistance without compromising durability.

So, what is a radial tyre?

Most mountain bike tyres use what's known as a bias-ply construction. In a traditional tyre, the casing threads run diagonally across the tyre from bead to bead, creating a structure that's strong and supportive but relatively stiff.

RAD CORE takes a different approach.

Using radial construction, the casing threads are aligned perpendicular to the direction of travel. This allows the tyre casing to flex more naturally as it rolls across the ground.

The result is a tyre that conforms more effectively to trail surfaces, creating a larger and more consistent contact patch between tyre and terrain.

In simple terms, more of the tyre stays in contact with the ground, more of the time.

Why does that matter?

A larger contact patch brings several benefits that riders can feel immediately on the trail.

More Grip

As the tyre deforms around roots, rocks and trail imperfections, it maintains better contact with the terrain. This increases mechanical grip and helps the tyre generate more traction in both dry and wet conditions.

Whether you're leaning into a loose corner or navigating an off-camber section of trail, the tyre is able to hold onto the terrain more effectively.

Greater Control

Grip is only part of the equation. The increased compliance of a radial casing also helps the tyre track the ground more consistently.

Instead of bouncing across rough terrain, the tyre absorbs impacts and follows the trail surface more accurately. This creates a calmer, more predictable ride feel, particularly when speeds increase and the trail gets rough.

Reduced Rolling Resistance

It might sound counterintuitive, but increased grip doesn't always mean increased drag.

Because the radial casing flexes more efficiently, it can reduce the energy lost as the tyre rolls. This allows the tyre to maintain speed more effectively while still delivering enhanced traction.

The result is a tyre that feels both planted and fast.

Improved Comfort

The additional casing compliance also acts as a form of suspension, helping to absorb trail chatter and small impacts before they reach the rider.

That means less fatigue on longer rides and improved confidence when riding technical terrain.

Built for modern mountain biking

While performance gains are important, durability remains critical for aggressive trail, enduro and downhill riding.

The RAD CORE construction combines its radial casing design with reinforced materials that provide excellent puncture resistance and impact protection. Riders benefit from the enhanced ride feel of a radial tyre without sacrificing the toughness needed for demanding conditions.

Spotlight: Nutrak x VEE Snap WCE MK2 Full 40 Compound RAD CORE

One of the standout tyres in the new range is the Snap WCE MK2 Full 40 Compound RAD CORE.

Developed in close collaboration with elite riders and optimised around the popular 2.50-inch width, the Snap WCE MK2 is designed as an all-rounder for mixed trail conditions at the highest levels of competition.

Its tread pattern combines ramped centre knobs for efficient rolling with large braking edges that deliver confident stopping power under hard braking. Deep tread blocks and generous spacing help the tyre dig into loose dirt and mud while clearing debris quickly for reliable all-weather performance.

The Full 40 Compound uses an ultra-tacky 42a rubber formulation designed to generate maximum grip. Its low-rebound characteristics help the tyre stay connected to the terrain, making it particularly effective for downhill and enduro racing where control is everything.

When combined with RAD Core construction, the result is a tyre that offers exceptional traction, predictable handling and impressive speed across a wide range of conditions.

Is radial technology the future of mountain bike tyres?

Radial construction has been widely used in automotive and motorcycle tyres for decades because of the performance benefits it delivers. Bringing that technology to mountain biking opens up exciting possibilities for riders looking for greater grip, comfort and control.

The Nutrak x Vee Tyre RAD CORE range represents a fresh approach to tyre design, challenging traditional casing construction and offering a ride experience that's noticeably different on the trail.

For riders seeking maximum traction without sacrificing speed or durability, radial tyre technology could be one of the most significant developments in mountain bike tyres for years.
