ALL-TOP Adjustable Auto-Stop Tire Deflator Valve Kit (10-30 PSI) 4 PCS Screw-on Tyre Air Down Tool for Offroad 4x4 (with 5 Valve caps)

安価な商品なので正確な空気圧の設定は出来ませんでした。 何度か試してみて希望の空気圧手前で大凡で設定、その後はエアゲージなどで手動で空気圧を合わせるなどすれば便利に使えます。 私はオフロード走行時に毎回使用してます。

The ALL‑TOP Adjustable Auto‑Stop Tire Deflator Valve Kit exceeded my expectations. They were very easy to adjust, and the first time I used them, they hit my target PSI within one pound. That kind of accuracy right out of the box is impressive. They also come with a storage pouch and metal valve stem caps, which are nice bonuses that keep everything organized and ready to go. The build quality feels solid, and the auto‑stop feature works exactly as advertised. I was so impressed with how well they performed on my truck that I bought a second set for my son’s truck. If you want fast, reliable, and hassle‑free tire deflation, this kit delivers.

A cost effective solution that takes most of the guess work out of airing down. Well built product that does what is intended to do and if not mistreated, will last long. They are not 100% accurate; may be off by 1-3 psi or so but just need to do your own “mini calibration” on the first go around and you’ll be happy.

Excelente
