While there are three basic types of Tire Valves: rubber snap-on, high-pressure snap-on, and high-pressure metal snap-on, it is the vehicle, desired tire inflation pressure, driving conditions, and wheel design that determine which type of valve Suitable for application.
To complement the wheel styling, the valve can be mounted on the wheel anywhere from horizontal to vertical. Near-horizontal valve positioning is the most common and is used by many wheel manufacturers to accept valve-mounted tire pressure monitoring system transmitters. While tire valves can work at any angle, valves mounted on a vertical shaft are more prone to pressure loss when used at high speeds due to centripetal force pressing down on the valve core and allowing air to escape.
Tubeless rubber snap-in valves allow a maximum cold tire inflation pressure of 65 psi and are designed for passenger car, light trailer and light truck applications, as well as off-road racing. Rubber snap-in valves can be used to mount 0.453" or 0.625" diameter holes in rims, and are available in lengths ranging from 7/8" to 2-1/2". While most rubber snap-in valves use plastic caps, some come with chrome sleeves and metal caps to help complement the look of custom or alloy wheels.
