A tire that uses an inner tube to retain air and is the most common type of tire available today.


A road tire that does not require a tube to retain air. A specially shaped bead that interfaces with the rim bead and a butyl liner keep a tubeless tire airtight. It can be used with or without liquid sealant. When used with sealant it provides another level of puncture protection and safety.


Usually a MTB tire that uses liquid sealant to make the tire airtight. This technology was developed to make Tubeless MTB tires lighter and more puncture resistant.


Normally a road racing tire in which the the tube is held in the casing by the tire casing being "sewn up" to retain the tube. Usually though of as the highest performing road tires. Tubulars are glued onto their special rims.



ZSG Active
This compound is very sticky and at the same time quite flexible, hence the name. Compared to other ZSG Compounds, Active is a softer compound, but still very durable.


ZSG Combo Compound
This compound is specially formulated compound that gives you unparalleled grip and improved durability than other sticky compoundsthrough a unique two in one layered compound tires stick without wear.


ZSG Dual Compound
Sticky for the turns and harder in the center. You’ll find it on the tires used in the grand tours, classics and Pro-Tour events. ZSG Dual Compound delivers the best of both worlds in tire performance.


ZSG Ultima Compound
ZSG Ultima Compound provides incredible grip in wet or dry road conditions and superior handling performance.


ZSG Natural Compound
This compound has the same low rolling resistance as the premium compound. Its enhanced wear resistance makes it perfect for a long lasting training tire with an excellent ride.


Dual Compound
Special compound developed for tubulars and pro racers. Dual Compound is similar to ZSG Dual in concept. Harder in the center for wear and efficiency and grippier on the sides.


Mile Cruncher Compound
Long wearing compound. More durable than our other compounds yet without the harsh ride of other competitor’s hard compounds. Mile Cruncher will roll the miles beneath you as you enjoy the ride.


Silica Compound
Adding Silica Compounds to tire treads vastly improves tire life, durability and grip. Depending on the use of the tire, varying amounts of Silica are added to balance tire wear and performance.


Air-Flex Lite Butyl Compound
We use this proprietary compound in our butyl tubes to enhance butyl’s natural benefits. The result is a tube that has the best balance of weight to strength while providing an exceptional road feel.



All-Contact Tread Profile
The shape of the profile has been optimized to obtain maximum grip performance from the compound.


Multi-Step Knob Shape
Multi-Step knobs have various heights molded into each knob. Stepped knobs help tires to perform in a multitude of conditions from hard to soft. Short big knobs are designed to provide an excellent ride.


3D Knob Shape
3D Knobs are designed to perform multi-directionally located on the tire sides. They are positioned in multiple directions to help maintain traction and durability while riding cranked over on the side knobs.



3 Dimension Casing
This incredibly strong casing is layered in a 3-Dimensional configuration to provide great road feel while protecting you from objects that may cut your tires.


Anti-Flat Casing
Anti-puncture reinforcement throughout the tire strengthens resistance to cuts and pinch flats.


Active Guard Casing
Active Guard is DH protection technology. We take a heavy duty 4-ply casing and a bead filler and ASB chafer to make an strong sidewall that can be run at low PSI without risk of blowing off or getting cut or punctured.



PT Casing Belt
PT Belt offers the same great puncture protection that PT Shield offers. The difference is that whereas PT Shield is bead to bead protection, PT Belt is placed only under the tread.


Protite Casing Shield

Protite Shield is a proprietary additive that adheres to the casing that makes tires 3 times more puncture resistant than other casing reinforcement systems.


PR Casing Shield
A structure that increases puncture resistance by using nylon taffeta to form a complete shield.


PR Casing Belt
PR Belt is a puncture resistant belt placed under the tread. It is lightweight and uses a strong fiber composition to achieve its puncture resistance capabilities.


PR Casing Wall
A nylon taffeta fabric is used on the sides to increase puncture resistance. PR Wall helps stop sidewall cuts and punctures.


Tough Lock Compound Belt
The super thick tread and colored inner layer of the TourGaurd Plus combines the best in puncture protection and great riding performance.


Tourguard is an Aramid fiber belt placed under the tread to improve puncture resistance without increasing tire weight or sacrificing performance.


ASB Chafer
When you see the ASB logo, it means that the tire has a proprietary anti-rebound rubber strip by the bead that reduces the chance of pinch flats by an average of 40 percent!



AX-A Casing Cord
AX-A technology uses extremely narrow cord which is weaved at a super high density into the casing for lightness and flexibility. This increased density improves resistance to cuts and abrasions.


400D Casing Cord
400D Cord technology increases side-cut resistance of our tires while improving the rigidity during cornering. This casing reinforcement helps protect the tube from punctures without adding weight to the tire.


800D Casing Cord 
800D polyamide cord is nearly twice as strong as the cord used in conventional tires. It improves rigidity, pinch flat and side cut protection. This casing reinforcement helps protect the tube from punctures.
