The AnttifySport TR413 snap-in tire valve stem is the standard rubber replacement valve used across most passenger cars, light trucks, motorcycles, ATVs, small trailers, lawn mowers, and wheelbarrows that run tubeless tires on 0.453 inch (11.5 mm) rim holes. It is the same shorty low-profile profile that tire shops, fleet maintenance teams, and powersport dealers reach for as the default everyday replacement, and it seats cleanly on the first pull-through with no clamps, adhesives, or specialty tools required. For dealers and importers, one stock SKU covers a wide range of service applications across automotive and powersport wheels.

The value sits in the material spec. The stem body is molded from ozone-resistant EPDM rubber — the same rubber family used on automotive sealing components — and the valve core is precision-machined brass. EPDM holds up to weather, UV, and ozone that would degrade natural rubber inside a season; the brass core threads cleanly and seats the valve cap without galling. Every stem is ozone-tested and leak-tested at the factory before pack-out, so the dealer or service shop seats a fresh stem, snaps it into a clean rim hole, and hears no hiss at the base on the first inflation.

The shorty profile is the headline for everyday wheels. At 1.25 inch overall length with a 0.66 inch outside flange, the TR413 sits low on the rim — clean visual line on alloy wheels, less leverage to catch on a curb or a brush guard, and a low profile that does not telegraph through the wheel well on sports cars and lowered setups. For deeper-dish wheels or trucks that need extra stem reach, the TR412 (1.46 inch) and TR414 (1.89 inch) share the same 0.453 inch rim hole and are usually stocked alongside TR413 in any tire shop’s daily inventory.

Installation is a five-minute job with hand tools. Deflate the tire fully, break the bead off the rim, and pull the old stem out from the inside. Lubricate the new TR413 stem’s base with soapy water or rubber lubricant, then insert it from the inside of the rim and pull through the 0.453 inch hole until the rubber flange snaps into place. Re-seat the tire, inflate to the vehicle’s placard pressure (TR413 is rated to 65 PSI), and install the valve cap. Best practice is to replace the stem every time the tire is replaced — rubber stems degrade with age and heat cycles, and a fresh stem is the cheapest insurance against a slow leak.

Compatibility covers the everyday automotive and powersport segments. Passenger cars (sedan / hatchback / SUV) and light trucks using the standard 0.453 inch rim hole seat TR413 directly. Motorcycles, scooters, ATVs, UTVs, and side-by-sides that use an 11.5 mm rim hole take the same stem. Small trailers, lawn mowers, garden tractors, and wheelbarrows round out the use cases that benefit from a fresh rubber stem at every tire change. For high-temperature service (track days, heavy braking, sustained high-RPM motorcycle riding), step up to a metal clamp-in valve — TR413 rubber is engineered for everyday street and trail use, not sustained high-heat duty.
