For the best ride use the stock sized tires and the lightest wheels you can get your hands on....probably the aluminum wheels off an 83 240d would be that. Bundts are the second choice.

I'm running the aluminum wheels with the wheel covers on my car with the Michelin Hydroedge 195/75r14 and bilstein shocks.

It rides like a sweetheart. It steers and stops nicely too.
