Tire Technology

 


       TIRE LEVELS       

TCS TOUGH HIGH GRIP (THG)
Glue-like conforming rubber draped over two full layers of casing leaves no area unprotected. Developed through real testing during the Enduro World Series, TCS Tough tires can take some serious abuse.

TCS TOUGH FAST ROLLING (TFR)
Long-wearing rubber laid across two full layers of casing leaves no area unprotected. Developed through real testing during the Enduro World series, TCS Tough tires can take some serious abuse.

TCS LIGHT HIGH GRIP (LHG)
Glue-like conforming rubber wrapped onto a gram-conscious casing designed to be compliant while still trail worthy. Who says High Grip needs to be heavy?

TCS LIGHT FAST ROLLING (LFR)
A fast and efficient centerline tread compound matched to sticky, low durometer side knobs coat a supple, gram-conscious casing designed to be compliant while still trail worthy.

ROAD PLUS
Supple plus-size traction and smooth riding characteristics for beyond where the pavement ends. Added tubeless compliance with higher volume drowns out road noise, gravel vibrations, and dirt imperfections.

TUBE TYPE LIGHT
Once called Race, our Tube Type Light tires have a lightweight casing paired to a folding aramid bead. This casing type is ideal for the rider using inner tubes but demanding high-end performance from their tires. These tires utilize a bead shape that relies on tire retention through proper installation and inflation of a properly sized inner tube.

FLAT GUARD (FG)
The Flat Guard level of WTB tires features an Urban Armor Casing, which provides additional rubber throughout the entire casing and sidewall to deliver additional puncture protection while also ensuring it holds up to cornering on asphalt and even the occasional curb rub. Additionally, Flat Guard tires utilize an extra layer of rubber beneath the whole width of the tread to provide even more thickness in the region where the tires are most likely to encounter sharp, intrusive objects.

COMP TIRES
Cost effective tires that feature grippy DNA rubber, durable impervious casings, and wire beads designed for use with a tube.

         CASINGS         


TCS LIGHT CASING

A supple, gram-conscious carcass designed to be compliant and conform to trail objects while still providing a happy balance of low rotational weight and rugged reliability.

TCS TOUGH CASING
Take our proven Lightweight Casing found in TCS Light tires and... well... double it. Yep, Tough Casing is composed of two full layers of casing, leaving no area unprotected on our TCS Tough tires. Developed through real world testing during the Enduro World Series, this casing is designed to take punishment and has been optimized for sealant usage, retention, and consistency.

SLASH GUARD (NEW)
Slash Guard features a nylon insert spanning the entire sidewall, from the tire bead to the outer knob. The insert provides additional sidewall protection without adding unnecessary weight. Nylon is a highly durable material that resists slashes and gashes, making it ideal for defending the most exposed area of the tire. Slash Guard provides an intermediate level of protection for those wanting extra sidewall durability without the weight of a dual ply casing. Slash Guard is currently only available on certain levels of tires with our TCS Light casing.

ROAD TCS CASING
The pavement-going brother of our TCS Light casing. Tubeless simplicity paired with unbelievable road-feel in all the sizes you want.

URBAN ARMOR CASING
Urban Armor Casing provides additional rubber throughout the entire casing and sidewall to deliver additional puncture protection while also ensuring it holds up to cornering on asphalt and even the occasional curb rub.

DURABLE CASING
A robust and substantial casing provides the strength needed for our wire bead tires to last. A high ratio of rubber to thread protects against trail threats and urban unpleasantries. Found in all Comp level tires.

RACE CASING
Now called Tube Type Light, it is a lightweight casing paired to a folding aramid bead. This casing type is ideal for the rider using inner tubes but demanding high-end performance from their tires.

        COMPOUNDS     

TRITEC COMPOUND (NEW)
Three compounds provide optimal levels of traction, support and durability. A base of high durometer rubber supports the entire tread and transitions into the knobs to prevent folding or squirming. Medium stiffness center knobs cap the base layer to provide traction and durability without sacrificing rolling efficiency, while soft compound side knobs deliver maximum grip and slow rebound for increased cornering traction.

DUAL DNA RUBBER COMPOUND
Dual DNA is the perfect mix of efficiency, traction, and durability. The centerline tread features a firmer rubber compound that boasts faster rolling and increased durability, while the side knobs are composed of softer, slower-rebounding rubber that improves control and grip.

DNA RUBBER COMPOUND
Our proprietary 60A durometer rubber compound offers the ideal mix of rolling efficiency and traction for Cross-Country and trail riding applications. DNA rubber is renowned for being versatile and long-lasting.

GRAVITY DNA RUBBER COMPOUND
The 48A durometer, glue-like conforming rubber creates uncanny traction with tuned rebound characteristics designed to take harsh hits yet not fumble for footing.

DISTANCE RUBBER COMPOUND
Found in WTB’s pavement tires, this compound is specifically formulated to maximize the lifespan of tires. Sick of wearing out tires yet don’t care to ride on a pair of Crayons? Try our Distance Compound for a harmonious pairing of longevity and traction.


       TERMINOLOGY    

TPI
TPI (threads per inch) refers to the thread count in a tire’s casing. A lower TPI indicates that thicker threads are woven into the casing, therefore making it more durable; a higher TPI indicates that thinner threads are used, therefore making the casing lighter and more pliable. WTB’s 60 TPI, TCS and Tube Type Light tires offer a supple casing with shock absorption qualities while remaining resistant to cuts and tears.

DUROMETER
The durometer of rubber refers to its hardness, which is rated according to its resistance to indentation. The lower the durometer rating, the softer the compound is. For example, a 42A compound will be softer than a 60A compound. Many TCS tubeless tires are made using multiple compounds with different durometer ratings.

SIPING
Sipes are small incisions on a tire’s tread. Siping a knob creates more working edges, which boosts traction in virtually any condition. Because WTB’s high-end mountain bike tires feature shallow sipes, the knobs stay firm under heavy loads and hard braking.

TIRE PRESSURE
The amount of air pumped into a tire affects its traction and ride characteristics. Too much pressure will result in a rough ride and lack of traction. Too little pressure will result in a squirmy ride and potentially unsafe bead retention that may not hold the tire on the rim while cornering. All WTB tires have recommended tire pressures indicated on the sidewall.

ARAMID BEAD
The area of the tire where it contacts the rim is called the bead. Tires with aramid beads utilize high-strength kevlar fibers that are spun into the bead to provide ultimate durability while also being lightweight and foldable. All TCS tires have aramid beads.

WIRE BEAD
The area of the tire where it contacts the rim is called the bead. Tires with wire beads utilize a thin, woven wire throughout the length of the bead to provide strength and proper tire retention. Tires with a wire bead cannot be folded. Entry-level tires are often made with a wire bead to provide them at an affordable price.

GMS (GLOBAL MEASURING SYSTEM)
Our Global Measuring System provides two measurements, the casing width and the overall width of the tread. Both are described in millimeters, with casing width written first.
