:agree: :agree: If you are ryding at the same indicated speed on your speedo as you were prior to the tire change, you are very likely now ryding somewhat faster than you were before!

hyea: The difference may be only 2 or 3% faster, but just as likely it may possibly be as much as 8 or 9%, and is very likely to bring your
ACTUAL speed over the ground much closer to being '
truly ACCURATE' than it was when you were still running the (worn) Kendas,
AND your trip meter/odo is now very likely telling you that you are travelling fewer miles too! Once again, it'll be bringing its reading closer to a truly
ACCURATE distance than it was before, when you were running the already 'notoriously small' Kendas that gave you some very optomistic speed and distance travelled readings even
BEFORE they wore all their tread off and the readings became more inaccurate/far more optimistic!! :shocked:
Check your speedo against an onboard GPS - even a 'street directory' type GPS or the one on your smartphone is likely to be accurate enough to give you a pretty good speed reading out on the open road, and I reckon you'll find that your 'dash reported' speed and distance travelled info is now within a mile or two of the GPS indicated info, instead of being the 'anything between 3 & 10% optimistic/over' that it would've been with the OE spec Kendas fitted! :thumbup:
And before too many people get all carried away with how their 'Kenda equipped' Spyder is more or less accurate than that, the inaccuracies in 'factory spec' speedo & odo/trip meters can be and usually
ARE somewhat different between individual machines, even those that roll off the production line consecutively; and this level of 'inaccuracy' is effectively mandated under International Agreements between Governments & Manufacturers that effectively specify all speed & distance measuring devices fitted to motor vehicles may read
OVER the
ACTUAL true speed &/or distance covered by anything up to 10%, but they cannot read
UNDER the true/accurate speed & distance!! And since the vehicle manufacturers who may be subject to penalties if their speedos & odo/trip meters lead their operators to believe their vehicles are travelling any slower than they really are/their true speed or travelling less miles than they really are on OE Spec tires & inflation etc, do you reckon too many of the manufacturers bust a gut to make their speedos/odos/trip meters are any closer to 'strictly accurate' than they need to be?!? Or might they just play it safe and aim for somewhere towards the middle of the 'permissable/acceptable range'?!? :dontknow:
BTW that % error
CAN be different (& often
IS different) between the speedo and the odo/trip meter on any given machine too!! So don't just
assume that because your
speedo was reading 10% fast that your
odo/trip meter was also reading 10% more miles travelled than you really covered!! Sure, it
COULD have exactly the same optimistic error, but it
may not necessarily have the same error!! :gaah:
PS: Recommended Tire pressures for 'non OE Spec Kendas'; ie, any a/mkt auto tires that you may fit (which are
NOT Kendas) that have load ratings that exceed those on the Kendas are probably going to be somewhere in the range of 16-18 psi up front; and 14-18 psi or maybe even 20 psi on the rear, varying a little for your individual needs/wants & loadings, ambient temps etc. Larger tires generally need a little less air than a smaller tire in order to support the same given load, so running slightly larger tires up front suggests that you should probably be running slightly lower pressures.... and anything over 20 psi in a 'real' auto tire on the rear is probably a little high! :lecturef_smilie: But if you like to risk the harsh ride, lesser traction, excessive wear on tire & suspension, et al which that brings simply because it '
feels better' to you or for any other reason, then that's fine by me!
