with an old stock engine I wouldn't be changing tyre sizes, but if you fit a more modern more powerful one then you have room for manoeuvre; the original tyre size and gearing was the best available compromise, the 0.82 fifth gear a little conservative but that was how VW could get the old engines through the real world emissions testing that came in 1985, prior to that they could run the engines dirtier at higher revs and pull a taller 5th gear

nice one, thanks.
