Review on 🔧 Enhance Wheel Stability with RealWheels RW0020VSB-2 2" Rubber Valve Stem Stabilizer by Jeff Henkhaus

High quality thick rubber, yes I have 2 stabilizers and they are thick elastic rubbers. The hole in my wheel is 1 3/4", so I trimmed it down a bit and it fits snugly and very neatly in my opinion. I've never found inserts for my wheel size so I got them to work. Picture below .I recommend this product.
