Tape over wheel balance weights

[GrahamH]

I second Vinces use of silver tape. Used on some race cars too. Sticks well and forms over the weights. Needs proper degrease tho. If the weights are falling off must be the prep for the bond or the adhesive on the weight. Most tyre guys I've observed give a wipe with a dirty rag and thinners or solvent. Cleaner prep and good amount of degrease should sort it. Or the weights used these days have a poorer adhesive. All bonding is about the glue and the prep. I had a weight fall off my smart rear wheel and the weight was still sticky, poor prep.
Decent brake cleaner , clean rag and degrease at least 5 times should do it. The wheels may have a silicone polish on from new.
Go for the foil to make sure,
