Good idea. I think my beemer front wheel is the worst ever. It has a huge disk rotor on each side that barely allow your fingers to get inside to the valve. Just trying to get the nozzle on the valve causes so much hissing it empties about half the tire pressure

Interestingly, the GS has spoked tubeless tires!
