Panaracer Smoke TiresPANARACER SMOKE TIRESThe Japanese National Tire Co. markets tires under the brand name of "Panaracer". In 1991, they introduced the "Smoke" tire family with great success, and have used the Smoke name on more recent though different models to capitalize on this initial success. The original Smoke tire we are told was designed at a meeting between Mr. Ken Masada of Interjet, (who represents National/Panaracer for sale to the United States), David Ajiki and Danny Otello, the founders of OnZa. Smoke tires come in 3 nominal widths. The Smoke Lite which is 26 x 1.9", the Smoke which 26 x 2.1", and the Smoke Magnum which is 26 x 2.2". All three models come Skin and Black sidewall and also come in a steel wire and Kevlar bead. The quality and workmanship on these tires is very high with no detail in the manufacture being over looked. Smoke tires rely on the same tread block design throughout the three tire widths. The design is merely "enlarged" proportionally with each tread block occupying the same percentage of tread stock surface as the tire models become wider. The Smoke uses two block patterns that are repeated around the tire. The first has a rectangular shaped tread block mounted horizontally across the tire with small indents at each end of the rectangle. At the sides of the rectangular tread blocks are large "boomerang" shaped blocks with the long leg facing in the forward rolling direction if you follow Panaracer's directional advice for this tire. Between each of the rectangular block patterns, in the tire center, are two smaller "boomerang" blocks. At the side of the smaller boomerangs are small triangle shaped blocks. The outer edge of the boomerangs and triangle rises at an angle, these Panaracer refers to as a raised "shoulder" and until they're worn off Panaracer suggests they assist in holding the tire's footing while turning. The side tread blocks on all Smoke models protrude from the sidewall, making the crown width wider than a measurement taken outer sidewall to outer sidewall. This is why the crown width and the section width numbers on the table are the same. Panaracer suggests the Smoke be used as a rear tire and their Dart tire be used for the front. The thread count on all these models is unknown, as is the casing fabric.
SMOKE LITE WIRE BEADThe Skin sidewall model uses the tire casing as its exposed sidewall. The tread on the Skin model tested to an 69/A hardness. The Black sidewall model is built using pigmented Black rubber on the casing fabric, which permits the exposed tire casing on the sidewall to appear that the tread stock encloses the tire with a real sidewall. The sidewall part of the tire is really exposed Black casing. The tread on the Black sidewall model tested to a 71/A hardness. Smoke Lite 26 x 1.9" - steel/Skin $ Price in Catalog |

In-depth Information About Metals Aluminum Aluminum is extracted electrolytically from bauxite ore. It is made by the electrolysis of aluminum oxide which is found in larger concentrations within bauxite ore. Bauxite is a mixture of the hydroxides of aluminum, together with other impurities such as oxides of iron, titanium, and silicon. Bauxite is produced by the weathering and change of aluminum silicate rocks usually found in tropical and semitropical regions where climate has produced an accelerated weathering process. Bauxite is not a rare ore and is widely available in the US, the Caribbean, and Europe. Approximately 4 pounds of read the full article... Beryllium Beryllium is a specialty metal that is steel-grey metal in color, with an extremely low density, making it very light weight. At 1.85 grams to the cubic centimeter, its density compares to that of magnesium. It is also a high strength metal, making it possible to design light weight, thin membered parts with ahigh stiffness. A column made of beryllium to support a load placed directly downward on top of it, will have a greater load carrying capacity, and be lower in weight than any other metal of equal size. Until the 1950's beryllium was used read the full article... Titanium The element titanium was discovered in 1763 by an English cleric, William Gregor who was an amateur chemist with an inquiring mind. It was in the black sands of Cornwall that he discovered the new element that had up to that time, attracted little scientific interest. A few years later, an Austrian, Klaproth, extracted the same element from an ore widely known as "rutile", which is a mineral consisting of titanium dioxide (one titanium atom, two oxygen atoms), that is a reddish-brown substance with a slight metallic luster. While rutile is the highest grade read the full article... Metallurgic Hardness Testing There are three types of tests used with accuracy by the metals industry,they are the Brinell hardness test, the Rockwell hardness test, and the Vickers hardness test. Hardness is the property of a metal which gives it the ability to resist being permanently deformed (bent, broken, or have its shape changed), when a load is applied. The greater the hardness of the metal, the greater resistance it has to deformation. Since the definitions of metallurgic ultimate strength and hardness are rather similar, it can generally be assumed read the full article... |
