Re: speedo drive correction

Very interesting. Useful info perhaps if fitting larger tyres. Is this both for 460 and 463?

Re: speedo drive correction

1st one fitted at last 8-) the rest will be a walk in the park
as these were odd size diffs
this guy had W460
originals were 4.8, which were 44:9, now changed to 4.1 so are 37:9 CW&P.
BFG A/T KO 245/75R16. rolling circumference of 2,360


quote Update:
this has completely eliminated the under reading of my speedo!
There "might" be 1 or 2 mph flattery at 40 mph, tough to tell with analog, but it's a fantastic improvement over the 10 to 15% it was understating before the change...
Very happy camper here..
