Earlier on in the year, someone was wondering about fitting an o/d to their pv, an had heard fitting bigger tyres would equate to having an overdrive.

I’m here to say it works! I fitted 185/80/15’s to mine. Result is a drop of 450 ish rpm at m way speeds. Much more relaxed cruising. You do loose a bit of acceleration, but not overmuch, a round town one doesn’t need to change gear hardly at all. I haven’t put them on front yet, to check wheelarch clearance, will update.
I feel this is worth doing, if just for cost reasons. Fitting an o/d to PV’s involves tunnel alteration, etc. 30 mph now comes up at 55kph, on my speedo.
