Hi guys, this is a little hard for me, I live in Ontario Canada.
That shouldn't be an insurmountable problem langevn; I live in South Australia on the other side of the World, but our cars and Spyders here Down Under
still use tires and there are retailers who will sell them & even strip & refit them for us if we can't/don't want to - even some (not too many tho!

) who'll take the wheel off the Spyder to do all that! :thumbup: :roflblack:
Sorry, I just hadta!! :shemademe_smilie: :dg2:
All that aside

regardless of the year &/or model, your Spyder is running car tires on car rims, so if you can take the wheel assembly off your Spyder and take it in to any tire retailer, they should be able to supply and fit a suitable tire. For the rear, apart from chasing the increasingly uncommon OEM size (possibly a deliberate ploy by BRP to try and force us to use their expensive & arguably crappy OEM Kenda tires!

) many Spyder Owners have found that just about
any quality tire in the sizes of 205/60 or 65; 215/60 or 65; or 225/60R15 will work well, especially if you don't run them at the 28-35 psi sort of pressures you need to run when they're fitted to a car that weighs 2-3 times more than your Spyder - for most, 16-18 psi is an ideal pressure for rear tires fitted to a Spyder. :lecturef_smilie:
Apart from that, do spend some time searching & reading the numerous tire threads that are already here on the Forum - we've got a
LOT of Canadian members here, and there are many of them who have mentioned the brand/model/size tires that works for them; so do the searching/reading if you want to go with any of those, or you can check out those threads & posts before making your own choice/picking
your preferred option in the tires that might be readily available from any of your local retailers in one of the sizes mentioned above. There's also a fair bit of previous discussion on how to remove the rear wheel; how to strip & refit the tire; getting the wheel balanced or not; what pressures are best and why; and a heap more - and I hafta add, it really doesn't seem to matter much which side of the border (or the World) you're on - tires seem to be something we all use and have at least a little interest in, and I don't think there's anyone who hasn't been able to find
SOMETHING to put on their Spyder.... at least, if they haven't found anything, they haven't told us here - not yet, anyway!! :cheers:
