TIRE ILLUSTRATION DOES NOT DEPICT AN ACTUAL PRODUCTION TIRE. THE ILLUSTRATION IS USED SOLELY TO DEPICT BASIC TIRE CONSTRUCTION. SEE INDIVIDUAL PRODUCT SPECIFICATIONS FOR ACTUAL INCLUDED PRODUCT TECHNOLOGY.
One layer of nylon wrapped from bead to bead. A single-ply casing conforms well to the terrain and is lighter weight.
DOWNHILL (DH) CASING
Two layers of casing material are used from bead to bead, providing additional protection and sidewall stiffness for downhill applications.
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.
The function of the bead is to keep the tire in contact with the rim while the tire is inflated. A rigid metal wire is utilized as bead material in applications where ultimate strength is needed and transportability is not a factor.
Foldable beads also keep the tire secured to the rim but are lighter weight and easily transported. The bead is made of spun aramid or Kevlar® fibers.
CARBON FIBER BEAD
A flexible material with greater strength to withstand the forces exerted by a high-pressure road tire.
