Those 205/55 x16 tyres are 4.3% smaller than standard, i.e. you are lowering your gearing (Bongo will rev higher at a particular speed), and the speedo will read fast.

225/55 x16 would appear to be the closest match, only 1% out.

Use http://www.miata.net/garage/tirecalc.html to try various width/aspect ratios for yourself.

Oh, and check the load rating on those tyres -you need at least 96, I think on a Bongo.
