Review on Protect Your Tires With CKAuto'S 10 Pack Anodized Aluminum Valve Stem Caps - Universal Covers For Cars, Trucks, Motorcycles, SUVs, And Bikes - Rust-Resistant Silver Caps. by Darby Perkins

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!
