I am sure there is more than one answer to this question....when I had my

wagon I acquired ssome of the IPD 15 x 7 turbine wheels ( like Bricklin

wheels) and used 205-60-15 with good results. The only thing that I recall

was slightly rubbing the fat front IPD sway bay at full turning lock.

When the same wheels were on a 122 sedan I needed an adjustable panhard

bar to centre the axle and get enough clearance. The wagon has a much

superior rear suspension setup including much more clearance for accessory

wheels. The big thing on the wagon is to ensure the aluminium blocks

in the trailing arms are in decent condition.

I still have the IPD wheels if anyone is looking....syd
