SWBs were originally fitted with 15" wheels and 16"s came later. Most cars were fitted with 5 1/2x16 (source: Ken Gross)

SWB road cars were fitted with 185mm wide Pirelli Cinturato tyres, whether 15 or 16" diameter. These had the usual 82 series aspect ratio, and 70 series low profile radial tyres didn't appear until the late 60s (1968 I think) with the Cinturato and Michelin XWX.

Doing some quick calculations, your 235/55x17s have an overall diameter about 20mm less than 185x16 tyres, whilst the 65s are about 20mm bigger. A 60 series tyre will have about the same overall diameter as the 185x16!

The 235/65s have approximately the same sidewall height as the original 195s (approx 150mm) whilst the 55s will be about 20mm less.

I think your car looks good with the 55s.
