Wheel Valve Stems

…tightened to spec so they won't break or loosen) and run-out (radial and lateral roundness for vibration-free rides) are recorded. Once assembled, each O.Z. Racing Tuner System 3-piece wheel gets a unique serial number noted on a sticker placed on the inside of the wheel near the valve stem.

…each O.Z. 3-piece wheel gets a unique serial number noted on a sticker placed on the inside of the wheel near the valve stem. So the next time you see an O.Z. 3-piece wheel, it's okay if you show a little respect and do some staring. These are wheels of distinction. Search Wheels by Vehicle

…& Wheel Package? When we sell a set of wheel and tires, we're happy to mount and Road Force balance the tires to the wheels at no cost prior to shipment. Given the TPMS sensors are located inside the wheel (opposite the valve stem hole), the sensors (if requested) need to go in the wheel…

…and brass valve cores are available. The nickel-plated valve cores must be used in the aluminum valve stems of tire pressure monitoring sensors because using a standard brass valve core in an aluminum tire pressure sensor valve stem will experience galvanic corrosion and the brass valve core will…

…stem shown below is attached to the tire pressure monitoring sensor? (Roll your mouse across the pictures to find out if you were right.) Only the rubber TPMS valve's resistance to gentle bending confirms its design. The presence of aluminum valve stems (shown below left) bolted through the wheels,…

…nice set of black wheels only to have your eyes wander to the bright silver valve stem. These silver valve parts look out of place on a black aftermarket wheel. Tire Rack offers an optional black TPMS sensor / valve part kit for $2.99 per wheel. Therefore, when you order black wheels like the O.Z.…

…equipped with a Tire Pressure Monitoring System. A majority of the vehicles come with a battery powered sensor attached to the wheel on the opposite side of the valve stem. Now that the law has been in effect for five years, we're starting to see some of the systems in need of replacement. Most…

…marks to reference later. There was a time when the valve stem hole on standard wheels indicated the optimum place to which the tire should be match mounted. However, with the advent of styled, steel wheels and aluminum alloy wheels, the stem position evolved into an aesthetic issue rather than…

…the valve stem stamp diagram that is located on the backside of the wheel cover. The valve stem on your wheel will fit inside this indent. See Figure 1. * Check each ring insert to make certain that the indent is facing down and inward (away from you if you are looking at the backside of the wheel…

…humidity. Always use a high quality air pressure gauge for consistent results. It is also recommended to use metal rather than rubber valve stems in the wheel, these being more resistant to high temperature.

…of either 18" or 19" wheels. Given the E63's prodigious horsepower and torque, most E63 drivers are best served by 255/40R18 in the front and 285/35R18 in the rear on 18" wheels or 255/35R19 in the front and 285/30R19 in the rear on 19" wheels. Tire Pressure Monitoring System…

…pressures. There are two types of systems, a direct TPMS and indirect TPMS. A direct TPMS uses a serialized sensor inside the wheel, often attached to the valve stem which sends a radio frequency to an on-board computer. An indirect system uses the vehicle's anti-lock brake system (ABS) to…

…Note: A standard brass valve core used in an aluminum tire pressure sensor valve stem will experience galvanic corrosion, and the brass valve core will eventually seize in the valve's aluminum barrel. Only special nickel-plated valve cores should be used in aluminum tire pressure sensor valve stems.
