I have alloy wheels that aren't exactly thin...** A: Perfect **Q: DOT approved?** A: Yes they are. **Q: How do you know whether you need 7" or 12"?** A: You need to get down and look and measure. There is no automatic answer. It depends on how your wheels are mounted together and where the valve stems are. Measure from the inside valve stem to the location where you intend to mount the other end. You want to use the shortest length possible. If you install extensions that are too long, then (in my experience) they may unthread themselves due to constant bouncing. **Q: Can these bend 180 degrees?** A: Yes but not in to tight of a bend ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by S***L on November 1, 2024* I used these to help float a boat lift by extending the valve stem. They worked great for that application. ### ⭐⭐⭐⭐⭐ no problems *by P***E on November 13, 2025* work as it should ### ⭐⭐⭐⭐⭐ Generic direct to wheel fasteners *by I***T on February 8, 2025* Its all good but.........I'm not fully satisfied with the generic clamp mount. The clamps are too raw and brute to fasten to a chrome hub without risking damage. Even with the added hose the wheel covers and hose mounts cannot seem to find a happy coexistence. I have already found a better solution since this purchase. ## Frequently Bought Together - Tiziri 4PCS 12" Tire Valve Stems Braided Dual Tire Valve Stem Extension Truck RV Trailer Wheel 300mm New Extender Rod - 6-Pack Valve Stem Extenders, Mellbree 45 Degree 90 Degree 135 Degree Schrader Tire Valve Extension Compatible for Dual Wheels Passenger Cars, RV, Stroller, Bicycles, Motorcycles and Trailers - Hotop 4 Pieces Valve Stem Extension Stainless Steel Braided Extenders, 6 Pieces 45 90 135 Degree Brass Extenders for Cars Trucks Motorhome Trailer Rv Trailer Vehicle(7 Inch, 12 Inch,Silver) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/128132324-tiziri-4pcs-12-tire-valve-stems-braided-dual-tire-valve](https://www.desertcart.jp/products/128132324-tiziri-4pcs-12-tire-valve-stems-braided-dual-tire-valve) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-28*
