Lots of discussion of snow tires. I purchased Hakkepellita H2s and have driven in all kinds of cold, snowy and icy conditions. Performance has been excellent. I have a different issue - very frequent balance issues. I suspect that this is caused by the inside of the turbine wheels gathering snow, ice, sand and salt. The gathered material is not evenly distributed and causes the wheels to be out of balance. The car drives with a shake that grows with speed. Does anyone know of a wheel that is designed to slough materials from the inside of the rim, rather than gathering it?
