The taller tire also gets your speedo REALLY accurate. The odometer will be about 2% slow, though.
.
Just be aware that no two speedo's or odo's/trip meters will
necessarily have exactly the same error, unless they've been very carefully calibrated to do just that!! And I seriously doubt that BRP or any of their component suppliers actually do that too often! :lecturef_smilie:
So whatever tire change works
FOR YOU to get your speedo dead accurate
might work for someone else, but the chances are that it'll more likely correct
to some extent in the same direction, but not
necessarily quite as precisely - it could be a bit worse, or possibly it could be even better!
Similarly, while in
your case Steve, when you've fitted these tires and ended up with an accurate speedo and an odo that's 2% slow, that's
not necessarily or even highly likely to produce
exactly the same result for anyone else, altho it
IS quite likely to be somewhere in the same ball-park!!

And that's just as a result of the inherent differences there weill always be between sensors & electronic devices etc - I haven't even started in on the variations that any differences in things like ambient temps, tire rolling resistance, soldering connection quality, or wiring resistance &/or length et al might cause!! :shocked:
But going back to the OP's 'Nanny' question, it's
extremely unlikely that such a small change in the rolling dia of your tire will have
ANY impact on the ABS/Traction control, largely because the 'change in size' your tire choice brings with it is barely any greater than the difference between running a brand new tire with full tread depth vs running a completely worn out tire with
NO tread depth left!! And when you add in that the programming for the 'Nanny' not only
MUST be able to cater for
THAT difference, but it also must be capable of catering for any one tire going flat.... and if BRP is permitted to sell Spyders/Rykers in
ANY public auto market in the World, then it certainly still works if
THAT happens!!
So anyone telling you that a change in tire rolling diameter of
just a few mms is going to cause issues with the Nanny, ABS, or Traction Control is either deliberately trying to mislead you; or they have no bloody idea & are probably simply parrotting what they've been told to tell you by a person/organisation that falls into the former category!! :cus: :banghead:
Ps: I'm currently running a 205/65R15 Michelin that (within specified temp & presure ranges) is giving me a (tested & calibrated) accurate to a fraction of a kph speedo reading
AND accurate Odo/Trip Meter readings to a similar level - and they didn't need to make any adjustments to achieve either! :clap:
