You know that feeling when you nail a corner perfectly! You give full commitment, no second-guessing, knobs biting hard while the bike goes exactly where you're looking? Now picture that feeling on every corner. On every rock. In every loose, sketchy section you've been tip-toeing through all season. That's what RAD-CORE delivers, and it all starts with a change most people never think about: the inside of the tire.
What Is a Radial Mountain Bike Tire?
Here's the short version. Most likely, every mountain bike tire you've ever ridden uses what's called a bias-ply casing, where the internal threads that give the tire its structure crisscross at a diagonal angle, roughly 45 degrees, from one edge to the other. That design is older than the mountain bike itself, and it works fine, but it was never built around the demands of modern trail riding.
A radial tire runs those same internal threads at a much steeper angle, closer to perpendicular with the ground. That single change makes the tire flex more directly at the point of contact with the trail, spreading the footprint wider, absorbing impacts more efficiently, and keeping more rubber engaged with the ground at any given moment. In cars and motorcycles, radial construction has been the standard for decades. In mountain biking, it's only now arriving, and Vee Tire Co. is one of the first brands to bring it to gravity, trail, and e-mtb riders at scale.
Introducing RAD-CORE
RAD-CORE is Vee Tire Co.'s proprietary radial casing technology, precision-engineered for the specific demands of mountain biking. Rather than borrowing a fixed thread angle from the automotive world, Vee developed their own optimized geometry, one that captures the compliance and grip benefits of radial construction while keeping the sidewall stable and predictable when you're leaned over in a hard corner.
The result shows up in three specific ways on the trail.
More grip: The contact patch expands meaningfully compared to a bias-ply (aka non-radial) tire at the same pressure, keeping more knobs in contact with the ground through rocks, roots, loose dirt, and wet terrain. Grip appears in places where conventional tires lose it.
More control: The casing holds its shape under braking and cornering load without needing lower pressures to feel planted. You get the feedback and confidence of a compliant tire while still protecting your rims.
More comfort: The flexing casing absorbs repeated impacts rather than transmitting them straight into your hands and body. Rock gardens feel less punishing, technical descents feel more controlled, and fatigue accumulates slower over long, demanding rides.
What Makes RAD-CORE Different From Other Radial Tires?
Radial MTB tires are a growing category in 2026, so this is a fair question. Here's what separates RAD-CORE from the field.
Full 40 Compound, everywhere. RAD-CORE tires run Vee's Full 40 Compound across every knob, at a uniform 42a durometer rating from edge to edge. That's genuinely soft, genuinely tacky rubber across the whole tire. Plenty of designs use a harder center compound to improve rolling speed and softer edge knobs for cornering grip, which is a reasonable trade-off. RAD-CORE skips the trade-off. The casing handles rolling efficiency; the rubber stays focused on grip.
Vee builds the tires. Vee Tire Co. is the cycling division of the Vee Rubber Group, a tire manufacturer with over 40 years of production experience that controls the full process from raw rubber sourcing through final assembly. Vee also manufactures tires for other brands in the gravity and enduro space. RAD-CORE is built by the people who know this process from the inside out.
Three proven tread patterns. RAD-CORE doesn't debut on experimental treads. It launches on the Attack FSX, Attack HPL, and Snap WCE MK2, tires with real race history and independent reviews behind them. The Attack HPL in particular has been described by riders as making it "virtually impossible to break traction" in corners, which gives you a sense of where the Full 40 Compound and RAD-CORE together are taking things.
The Three RAD-CORE Models
Attack FSX is built for hardpack and bike park terrain where you need rolling speed and sharp cornering grip at the same time. It runs well front or rear and rewards aggressive riding on dry, firm ground.
Attack HPL (Hard Pack Loose) is our most versatile and most grippy gravity tire, developed on the World Cup circuit and trusted by riders who need a tire that performs across a wide range of conditions. Deep cornering traction and a casing that refuses to fold under hard loads.
Snap WCE MK2 is the all-rounder for mixed and technical terrain, it is also the fastest rolling of the 3 tires. Deep tread, even knob spacing to dig into loose dirt, and the kind of ride feel that makes chunky and root-heavy trails noticeably more manageable.
All three models are available in 27.5 x 2.50 and 29 x 2.50, run the Full 40 Compound, use a 72 TPI folding bead tubeless-ready casing, and carry an E-25 rating for e-bike compatibility. They start at $84.99 USD.
One note on pressure: because the radial casing gives you more compliance and a larger contact patch at a given PSI, We recommend starting at least at 5 PSI higher than your current setup. The contact patch advantage is built into the architecture, so that extra pressure still delivers more grip, not less.

Go Feel the Difference
The tire architecture that every mountain bike has ever used was never designed around what trail riding actually demands. RAD-CORE was. It starts at $84.99, runs on three tires that already earned your trust, and delivers on the trail in ways you'll feel on the first descent. Your local trails are the same. Everything else is about to feel different.

Radial Tire FAQ: Real Questions, Real Answers
Do radial tires actually grip better, or is it marketing?
The grip improvement is real and comes from physics. A radial casing allows the tire's contact patch to spread more freely at a given air pressure, meaning more rubber touches the ground simultaneously. Schwalbe's independent testing showed approximately 30% more contact area compared to a conventional bias-ply tire at the same pressure, and that figure has been independently validated across multiple brands since. More rubber on the ground equals more traction, and that holds up on the trail.
Will a radial tire feel soft or unstable in corners?
A poorly designed radial tire can, yes. The challenge with radial construction is that the same casing flexibility that creates grip can cause lateral instability under hard cornering load if the geometry isn't tuned correctly. RAD-CORE addresses this through the thread angle itself, optimized to keep the sidewall stable under lateral force without requiring foam inserts or extra reinforcement. The ride feels compliant and planted, not vague or wobbly.
Why do I need to run higher pressure in a radial tire?
Because the casing flexes more readily, a radial tire will feel softer at any given pressure than a bias-ply tire you're used to squeezing to check inflation. Vee recommends starting 5 PSI higher than your normal setup. That extra pressure keeps the casing in its optimal range, where you get the full contact patch benefit and the support to protect your rims. The good news is that even at that higher pressure, you'll have more grip than your previous lower-pressure setup delivered.
Are radial mountain bike tires more likely to puncture?
No. The puncture resistance of a tire depends on the number of casing plies, the thickness of the rubber, and any additional protection layers built into the design, none of which change based on the thread angle alone. A radial tire built with the same ply count and rubber thickness as a bias-ply tire will perform comparably in puncture resistance.
Can I run RAD-CORE tires on my e-bike?
Yes. All three RAD-CORE models carry an E-25 rating, which means they're built to handle the higher torque, added weight, and increased braking load that e-bikes place on tires compared to traditional mountain bikes. This isn't a blanket certification applied after the fact; it's built into the casing and compound spec from the beginning.
