Used on a 2015 Silverado and 20" fuel wheels. They seemed to be working fine. to have both. As far as I can tell, they serve their purpose. Although I have to say I've used the plastic wheels that wheel manufacturers usually supply with their wheels and I've never had a problem with them. And we have a 120 degree summer here. Recommended? Of course. But probably not necessary. It was just impulsive spending for me.
