I used clear silicone, in small quantities, on the backside of the center cap. Enough to hold, but (hopefully!) not so much as to make removal for maintenance a disaster. It does mean that a flat will leave me without a trim cap until the next overnight after the tire is repaired, but I figured I could live with that!

I just had Audi A4 15 x 7 Ronal rims centerbored for Cunegonde two
months ago. Had them done at a NAPA in inner SE Portland for about
$125/4. No problem having tires (Geolandars) mounted or balanced, but
the circular spring-wire retainer center cap needs an alternate
mounting - I think I'll use some rare-earth magnets pulling on the
studs/nuts. Unless somebody here has a better idea!
