The combination of a tubular tyre and its tubular rim is lighter than that of a clincher tyre and clincher rim, and will therefore always result in less rotating mass or a stronger construction. [5] Tubulars can also be used over a wider range of tyre pressures from 1.7 to 14 bar (25 to 200 psi), compared to the typical 6-9 bar on a clincher tyre.
The black residue remains from where the tire was seated on the "safety profile" rim. Thomas B. Jeffery's 1882 clincher rim patent Design The first pneumatic tires for bicycles were simple tubes in shape secured to the wooden outer concave surfaced circumference of the wheel by glue and air pressure pressing them against it.

A clincher bicycle tire mounted on a wheel A cross section of a clincher tire with a puncture-preventing layer (in blue) between the casing and the tread An inner tube rolled up for storage or to be carried as a spare. A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle.
There are three main types: clincher, wired and tubular. [41] Most bicycle tires are clincher and have a bead that presses against the wheel rim. An inner tube provides the air pressure and the contact pressure between the bead and wheel rim. [42] Industrial tires support such vehicles as forklifts, tractors, excavators, road rollers, and ...
However, tires not designed for the tubeless application do not have as robust a sidewall as those that are. [11] The drawbacks to tubeless tires are that they are notorious for being harder to mount on the rim than clincher tires, [11] and that the cyclist must still carry a spare tube to insert in case of a flat tire due to a puncture. [11]
Clincher A type of tire that uses a bead around the edge of the tire to attach to the rim of the wheel when inflated. The inner tube is separate. [7] Closing the door When a rider chooses to take a line (often toward the apex of a corner) with intent to block a rider behind them from successfully passing. Commissaire
These include a system for wind-tunnel testing prototype shapes with fully inflated clincher tires, and the use of thermal imaging to analyze braking performance. Zipp also developed a heat-resistant composite resin to reduce rim temperature during heavy braking. [7] Firecrest technology was developed from Zipp's earlier “toroidal” rim ...
