Jim – Hi, I too have recently purchased a set of LAT 9 wheels and have been pondering the balancing issue. It occurred to me that other European cars use solid-center wheels, and a Google search turns up many UK-based forums for cars such as Citroens. One posting had a link to a YouTube video which showed the use of an adapter on the balancing machine that allowed the wheel to be bolted to it using the lug nut holes.

It got me thinking that there might be a local Citroen owner that could point you to someone having such an adapter who would be capable of balancing solid-center wheels. There are a few Citroen 2CVs in my area – I’m going to keep my eyes open at the local car shows this summer for the owners and ask them about their wheels and tires and how they were balanced. I’ll let you know what I discover.
