Tioga Psycho Tires
TIOGA PSYCHO TIRESThe Psycho tires, made in Japan by Mitsuboshi, use a 1 5/8" repeating tread pattern with nylon for the casing fabric. At the outer sides are stout tread blocks with supports from the sidewall area. They are largely rectangular shaped blocks with a short inner leg, the visible line that appears to separate the two pieces is a 2mm deep sipe to push water out. Between the edge tread blocks is a smaller replication of these outer blocks including the 2mm deep sipe. In the center, there is also a single multi-sided block with a two siped surface. The Psycho is made in a wire beaded model with either a Black or Skin sidewall and a Kevlar beaded model with a Skin sidewall. The wire bead model with Black sidewall is made with Black rubberized casing fabric so what appears to be an actual sidewall is really the exposed tire casing. The wire beaded, Black walled Psycho has a tested tread rubber hardness of 65/A. The wire beaded, Skin walled Psycho has a tested tread hardness of 62/A. The Psycho-K with the Kevlar bead has an exposed Brown tire casing with a tested hardness of 63/A. A final version of the Psycho, having a Kevlar bead, has a Brown casing, making a Skin side wall, and Amber colored tread. The Amber color is to show its lack of carbon content, and hence that it is by nature a soft rubber compound used to make the tread stock. In fact the tread measured a an 52/A hardness which is the softest of all tires we've tested. We have received some of these Amber tires with the casing fabric being clearly visible at the inner base of the outer side blocks. This indicates a thinness of the tread stock prior to molding and vulcanizing. This tread thinness will result in real vulnerability of the tire against sharp objects trying to penetrate at the thin point. It will also lead to a likelihood of tread block separation from the tread stock and casing leaving a void in the tire tread. We have tried to intercept this flaw as it appears in our inventory, but it seems to be a continuing experience. Should you buy an Amber Psycho elsewhere, look for this defect. The Psycho- II tire is based on a modified version of the Psycho tread pattern. The Psycho-II tire is made in a Taiwan factory, making a less expensive Psycho available for original equipment and after market purchase. Psycho 26 x 1.95" - 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... |
