Maxxis Tyre Technology Definitions
Carcass Technology
 SILKWORM CAP PLY
Silkworm Technology is an exclusive material incorporated into the casing of select Maxxis tyres. The Silkworm material helps to increase puncture and tear resistance, while at the same time increasing rotation efficiency. |
 BUTYL INSERT
An extra layer of butyl rubber wrapped around the bead of a Downhill tyre that helps prevent pinch flats and protects the rim from hard hits. |
 KEVLAR® COMPOSITE (K2)
Available in select tyres, this Maxxis exclusive fabric provides more puncture protection than both standard Kevlar® and Vectran®. The addition of this lightweight and supple material ensures that the ride quality and performance remains unsurpassed. |
 NYLON BREAKER
The nylon breaker is a reinforcement option that offers protection from punctures directly under the tread area. It also helps increase rolling efficiency by providing support to prevent the tread from flexing. The nylon breaker is available in select road tyres. |
 KEVLAR® BELT
Made from material used for bulletproof vests, a Kevlar® belt provides maximum puncture protection in the most unpredictable conditions. Unlike traditional belts which merely disperse Kevlar® among other materials, the Maxxis Kevlar® belt contains only this state-of-the-art fabric. The specially formulated Kevlar® belt is positioned between the tread and casing layer. |
THREADS PER INCH (TPI)
The number of nylon threads that cross through one square inch of the tyre’s casing. Only one ply of a dual ply casing is counted. Lower TPI gives better puncture and tear resistance, but is heavier. Higher TPI conforms more to the terrain, offering a smoother, more supple ride. It is also lighter weight.
SINGLE PLY
One layer of nylon holds it all together. Wrapped form bead to bead, a single ply conforms well to the terrain and is lighter weight.
DUAL PLY
The nylon of the casing is folded over to provide two layers of protection. True, it’s heavier, but in Downhill applications the extra puncture resistance is essential.
RUBBER COMPOUNDS
The most obvious and arguably most important part of a tyre is the tread compound. By changing the amounts of various components of the rubber compound formulation, engineers can make two tyres that look identical but perform differently. Below are some distinct characteristics of our most popular compounds.
70a
- Long tread life
- Low Rolling Resistance
62a eXCeption
- Great Traction
- Low Rolling Resistance
60a MaxxPro
- Great Traction
- Minimal Impact on Tread Life
42a Super Tacky
- Awesome Grip
- Stable Knobs Prevent Squirm on Hard Pack
40a Slow Reezaay
- Located on outer surface of shoulder lugs on 3C Downhill tires
- Provides unparalleled grip while cornering and slow rebound technology
A specification that combines 120 TPI and a 62a compound to provide lightweight advantages and exceptional traction. The eXCeption Series is available in select mountain treads and are ideal for racing.
3C TRIPLE COMPOUND – ROAD
3C ROAD – TRIPLE COMPOUND TECHNOLOGY, INVENTED FOR OUR ROAD RACING LINE
Maxxis is proud to be the first bicycle tire manufacturer to use Triple Compound Technology: three different compounds in the tread of a single tire. Partnering with silica manufacturer Degussa, Maxxis has developed these compounds to optimize grip in tight corners at severe lean angles and offer great tread life. With the three compounds’ placement optimized, you won’t feel the transitions – just the grip.
- High Dispersion Silica center tread for long life and low rolling resistance
- Two progressively softer silica-based compounds provide increased grip in tight corners
- Precise placement of three compounds maximizes transition grip at different lean angles
- Improved wet traction over current Road Racing tires
- Three distinct silica-based compounds of varying hardness (50a, 58a, 62a)
- K2 breaker with Silkworm cap ply
L.U.S.T. TECHNOLOGY
LIGHTWEIGHT ULTIMATE SIDEWALL TECHNOLOGY
Maxxis Mountain Tubeless tyres, certified to UST® standards, now feature Lightweight Ultimate Sidewall Technology (L.U.S.T.). L.U.S.T. offers better puncture resistance, improved air retention, better longevity and lower weight than previous tubeless technologies. Maxxis engineers were not content with simply having one of the best tubeless tyres on the market. Instead, they went back to the drawing board, reinvented the tubeless tyre from the casing and tread and addressed your concerns about tubeless technology. By adding a thin fabric layer to the sidewall, covered in a special air-tight rubber compound, Maxxis created a casing that is lighter, tougher and holds air better.
- 15% lighter than Maxxis’ previous tubeless tyres
- Better air retention than competitors’ tyres
- Increased sidewall puncture resistance
3C TRIPLE COMPOUND – DOWNHILL
3C DH – TRIPLE COMPOUND TECHNOLOGY, INVENTED FOR OUR DH RACING LINE
Maxxis has revolutionized the DH racing scene again. By combining the best properties of our most popular rubber compounds, Maxxis has created a tyre that brakes and corners better than previously thought possible, while offering tread life approaching that of their harder compound tyres. True to their focus on delivering the best possible technology to all riders, Maxxis isn’t hoarding this breakthrough for professional racers: it is also offered in your favorite tread patterns.
- Optimized compound in side lugs for stable cornering without rebound-induced bounce
- High-traction compound in center lugs for braking and straight-line control
- Harder base layer supports knobs to minimize movement and flexing under immense cornering, braking and landing forces
