Review on CKAuto Yellow Anodized Aluminum Tire Valve Stem Caps (10Pcs/Pack) - Corrosion Resistant Universal Covers For Cars Trucks Motorcycles SUVs & Bikes by Tim Thornton

I bought these because I thought the knurling on the cap would help make it easier to put on and off. old hands and all that.these were no better than the smooth caps that came on my vehicle. they are also a bit to long. can not really tighten down before the bottom hits the rubber of your valve stem.I should have returned them!
