On The Issue Of Purchasing Radial Tires

Before coming to buy a brand new set or single replacements of your radial tires, you should come to know a little more about what kind of tires you actually own, and you must become aware of what particular brands may be the best for you to use depending upon your vehicle’s needs. First off, a radial tire is a pneumatic tire that has a radial-ply casing, and the ply cords extend to beads that are laid at approximate right angles to the centerline of the tread.

The radial tire is a particular type of automobile tire that was originally developed by Michelin, and because of its’ advantages over any other types, the design has become the standard for almost all automotive tires. The tires end up being made up of more than just rubber, as those tires would be far too flexible and weak, but instead are reinforced by a series of plies of steel and nylon cords within the rubber tread. This casing is made up of various layers divided between the tread and the sidewall at the surface of the tire, and the liner and various plies and belts underneath those layers.

The fabric of the tire used to be built up on a flat steel drum, with the cords crisscrossing each other at an angle from the direction of travel, and this they called cross ply or bias ply tires. With the plies turned up around steel wire beads, and then the combined tread



and sidewall would be applied, creating the new tire to be put into a curing device and shaped into the mold. This shaping process would cause the cords in the tire to assume a distinctive shape from bead to bead, the angle under the tread went down about 36 degrees from the top, and this was called the Crown Angle.

In the sidewall region, the angle was 45 degrees with bead remaining at a standard of 60 degrees, and the low crown angle gave this design rigidity to support the tread with the high sidewall angle giving comfort. Being a little bit more aware of the construction of the radial tire may just help to make you a bit better at deciding on what brand of radial tires might best suit your needs with a little more research into the topic, and comparing prices at various local outlet retailers and auto parts stores.
