It isn't of any concern on any o ne of all those other vehicles either, is it?! Besides, the VSS is designed to handle all sorts of variables, including different tire pressures & therefore differing rolling diameters, traction, road surfaces, etc, so something like a better made tire is going to be absobloodylutely nothing to the VSS!! And then there's the millions of miles of 'free testing' that's been done by thousands of Spyder Ryders over the years, with not one reported concern with the traction/stability systems or the entire VSS reported (in fact, quite the opposite!) IMHO, it's nothing but manufacturer scare tactics & double-speak to make owners scared of using anything but their low quality high priced excuse for a tire!

And here in Aust, all vehicles that are approved for sale &/or 'grey import' must be able to run any 'design approved tire' that is within the approved +/- legal size range and that meets or exceeds the load & speed ratings & the construction type. So basically, any Pasenger construction type tire that will fit on your Spyder without modding the swing arms or front suspension under the OE tupperware is almost certainly a legal fitting! But it is up to you to decide if you want to run any tire other than the Kendas. I know what choice I've made!
What are you running Peter.
