The Science behind Maxxis' Tires

Whether it's the grueling demands of long-distance road racing, the punishing demands of mountain biking and cyclocross or the exhilaration of BMX riding, Maxxis tires have become renowned as the ultimate cycle tire for enthusiasts and professionals around the globe.

We place great importance on providing cyclists with the best products possible and we are constantly striving to discover ways in which to improve and innovate the tires we offer.

The technology that goes into making every Maxxis cycle tire is intelligently and thoroughly researched, bringing you products you can trust and rely on throughout your life's journey in cycling.

Here, we reveal some of the inner-most technology and revolutionary science behind the tires on your bicycle. 


Tire Construction Technology

 1. Basic Tire Construction

BEAD
The function of the bead is to keep the tire in contact with the rim while the tire is inflated.

WIRE BEAD
 A rigid metal wire is utilized as bead material in applications where ultimate strength is needed and transportability is not a factor.

FOLDABLE BEAD
 Foldable beads also keep the tire secured to the rim but are lighter weight and easily transported. The bead is made of spun aramid fibers.

CARBON FIBER BEAD
 A flexible material with greater strength to withstand the forces exerted by a high-pressure road tire.

CASING

SINGLE-PLY CASING
One layer of nylon wrapped from bead-to-bead. A single-ply casing conforms well to the terrain and is lighter weight.

DUAL-PLY CASING
Two layers of casing material are used from bead-to-bead, providing additional protection and sidewall stiffness for enduro and downhill applications.


B.) Wide Trail Construction



Wide Trail (WT) construction optimizes the tire’s tread layout and profile on today’s modern, wider rims. Traditional tires are designed around older, narrower rims and can create an overly square tire profile, leading to less than optimal performance. WT tires are optimized for a 35mm inner rim width but are proven to work over a range from 30-35mm inner rim widths, depending on the rider’s preference.

Maxxis Wide Trail XC tires are optimized for use with 30mm internal width rims, but they will perform well on rims as narrow as 25mm. Maxxis does not recommend rims wider than 30mm or narrower than 25mm


C.) Tubeless Ready Downhill



Tubeless downhill set-ups are a great way to shave some weight and spend more time in the bike park or shuttling hot laps on your local runs. Sealant-compatible rubber is used with the familiar Maxxis dual-ply 60 TPI downhill construction and butyl insert for support and rim protection in order to offer the benefits of increased grip and reliability. A Tubeless Ready bead securely locks to the rim and the foldable bead provides additional weight savings.


D.) Tubeless Ready Road 



Tubeless technology that combines a carbon fiber bead for strength, a bead cushion for security, and a liquid-sealant compatible rubber for air retention, eliminating the need for an inner tube. The puncture protection layer helps prevent damage from road debris. Liquid sealant may be used to prevent any loss of air pressure. Choose Maxxis Tubeless Ready road tires for the ultimate road experience.


E.) Tubular



A traditional tire construction in which the tire casing is sewn or wrapped around an inner tube. These types of tires must be glued or taped onto tubular-specific rims.


F.) Threads per Inch (TPI)



The number of threads that cross through one square inch of a single ply of the tire’s casing. Lower TPI gives better puncture, cut and abrasion resistance but is heavier. Higher TPI conforms better to the terrain, offering a smoother, more comfortable ride while reducing the weight of the tire.

Maxxis TPI ratings are the threads-per-inch of a single casing ply, as compared to some competitor TPI ratings.


Puncture Technology

A.) Silkworm

Silkworm is an exclusive material incorporated into the casing of select models, increasing puncture and tear resistance. Silkworm is featured under the tread as a breaker.

B.) Silkshield



SilkShield offers protection from bead to bead whereas Silkworm is found under the tread only.

SilkShield provides an additional level of protection for sidewalls as well as under the tread.
