Casing Technology

Tire casing is the fabric that the rubber compound adheres to. The fabric of the casing can be made in varying thickness and threads per inch (TPI). Generally, the higher the TPI number, the more supple the tire sidewall will feel and flex. This means a more comfortable ride compared to that of a lower TPI casing. The casings can be treated and reinforced with various materials in order to achieve different degrees of puncture resistance and ride qualities.

ENdurance 1 (E1)

The pinnacle of dual layer flat protection; Endurance 1 takes the bead to bead Aramid protection of Iron Cloak on a 120tpi casing and then tops it off with another layer of Iron Cloak at the tread area. Offering true double Aramid protection at the tread with a single layer guarding the sidewalls. Durable, light, and race ready performance.

Endurance 2 (E2)

The original Endurance dual layer flat protection; featuring the Iron Cloak bead to bead protection and 120tpi casing offered in the E1 level tires we have topped it off with the K-Shield flat protection under tread to offer additional puncture resistance plus additional mileage for your ride.

endurance 3 (E3)

The performance level dual layer flat protection for city, urban, and trekking tires. We have laid an Iron Cap puncture belt across the 60tpi casing for full tire protection and topped it off with the same K-Shield from the E2 level tire for additional tread life and flat resistance.


Kenda's best puncture resistant material, a blend of Aramid fibers, is laid up on the tire casing from bead to bead. Not only does this provide puncture protection underneath the tread of the tire, but it also reinforces the tire side walls minimizing slashes or tears; with a minimal addition to the overall tire weight.


A thin strip of Kenda's best puncture resistant material, Iron Cloak, built in directly underneath the tread rubber only, for added puncture protection and minimal weight. Iron Cloak Belt lets you rest assured that your tires are durable, but light and super supple for the ultimate in riding performance.


A layer of aramid and ceramic particles inside the tire under the tread area only. Designed to prevent punctures. This is Kenda's first line of defense against punctures.


A layer of material that runs from bead to bead under the tread to prevent flats. IRON CAP combines some of the technology from the high-end IRON CLOAK material without all the added cost.


Utilizing the same protective material that is in the full Iron Cap protection but limited to just under the tread surface, offering added puncture protection at a minimal cost and weight addition. Previously known as PRC2.


Or Casing Ply, as it has been referred to, is an added layer of material that is under the tread area and runs from bead to bead. Generally used in Kenda Premium Downhill Tires as a puncture resistant material designed to prevent pinch flats.


All over tire protection designed with the challenges of Enduros and Downhills in mind. A super supple 120tpi casing that is sheathed in a 3 piece casing protection to resist punctures while being optimized for tubeless performance. The sidewalls are further supported with a butyl insert for strength and pinch flat resistance. Resulting in a light weight tire for whatever gravity throws you down.


Kenda SCT (KSCT) is the optimization of Kenda Tire sidewalls via the addition of a second ply of fabric that allows for better air and fluid retention when a tire is run tubeless. The SCT ply also serves to add an additional layer of protection to the tire against sidewall cuts and abrasions, and pinch flats when using a tube. This makes the tire truly Tubeless Ready.

Tubeless Race (TR)

Tubeless Race is the lightest tubeless ready version tire Kenda offers. Utilizing a modified bead shape for better tubeless sealing and performance while offering the lightest and softest riding sidewall available. When it’s race day, make it Tubeless Race.
