Technically true. But I am not sure how much real life difference there is. Especially when you consider you're going from a very wimply sidewall/tread area car tire to a real car tire. It would be interesting to see how much real world agility you actually lose with this swap.
I've done a fair whack of testing on tires over the years, using tracks & facilities that are designed to highlight the tiny differences there may be between otherwise close to identical tires from different manufacturers, & after doing similar back to back testing on the Spyder & various tires, never before have I seen such a marked difference between an OE Spec tire and
every a/mkt replacement that we've tried (& btw, that's even
before we got into the top end performance tires!!) so much so that I'm absolutely & unequivocably convinced that the one word answer to that question above can only because
NONE! :shocked:
In fact, your Spyders' responsivenes & agility is most likely to only
IMPROVE SIGNIFICANTLY by fitting a car tire, even if that car tire does have a taller profile than the OE tires!!? And the agility is likely to improve even more so if you replace the OE Spec Kendas all round & fit better quality stronger car tires up front too! And as you suspected Ron, this is all pretty much due to the stiffer sidewalls & tread on the car tires, the greater contact patch that enables, & the better transfer of road forces into the chassis that's enabled by a tire that is constructed to do that a
LOT more than the lightly constructed OE Spec limp dishrags that BRP tries to convince us are actually 'special tires' will ever do!
Altho if asked are the Kendas are 'Special', the answer must be
absobloodylutely!!

Special at being mediocre, special at flexing WAAAYYY too much & letting the contact patch lift during cornering, special at underperforming in so many ways
so much that it degrades the capabilities of our machines significantly!!! :cus: There's a perfectly good reason that the overwhelming majority of Ryders who
do make the move to better quality car tires never even consider going back to the OE Spec Kendas, and it ain't (just) cos the car tires are frequently cheaper as well as longer lasting either!
