255/85's pretty much correct your speedo.Quote:

New 255/85's correct it so that the speedo would be damned near 100km/h @ 100km/h actual road speed according to the GPS I borrowed.
Could I also expect a reduction in the RPM at the same speed with the 255/85 oposed to the 235/85's?
If it's corrected the speedo by 8% I'd reckon so ;)Quote:

On the open road the taller gearing is better IMO, but firsts a bugger, particularly when towing.
In what way is it a bugger? I have a clutch issue at present, going to be fixed very soon I hope!!!!!!!
Fitting a 255/85 is a larger diameter tyre so you've effectively raised your gearing by 8% or so.
With a Tdi when towing you either need to start in low range second gear and shift into high range when you need another gear (high second) or slip your clutch a hell of a lot more on starting.
Am I reading this right?Quote:

all speedo's are inaccurate to some degree, i think its and ARD thing. Nearly all cars i have driven with a GPS the speedo can be out as much as 5kms @100km/hQuote:

The speedo being inaccurate with the standard tyres is pretty normal these days, the ADRs state that a speedometer can vary by up to 10% from the cars true speed BUT it cannot read slower than the true speed. New VWs have a the ability to show ECU data on the nav screen including speed as sceen by the ECU – it’s spot on, and the instrument panel speedo is high by 6-8%.
