TR412 is a short stem. Commonly used on ATVs, lawn tractors and other small tires. You rarely see them on real car wheels. I prefer them because they have a low profile and I think they look good and are good when you're at close range. If you want a "standard size" stem, then the TR413 works best with aluminum wheels, the medium TR418 works best with hubcaps, and the long TR423 works best with old-school deep metal hubcaps. Most cars now come with TPMS, but if they don't then you know it.
