Not just civilised we are also awake! I was hoping you (and Mike) would chime in Peter. Mine has the raised middle. See picture if I have got your comments correct. Absolutely 15s on it as it is a 2014. Excellent info so it looks like Contis then. Are you able to say why and what you are running now? or is it a state secret, after all your borders and ours for that matter are closed with the state who shall not be named.
Thanks for all the info.....
That's definitely the 'New style' fenders, so you should be fine with the 175/55's!

As to what & why re
my tires now, I'm actually running Kumho's up front, cos they are a pretty reasonable 'Sport/Touring' tire that grips pretty well for a sporty tire with a fairly long lasting tread compound that works well in the extremes of hot or cold and wet or dry roads that we get here - so I generally get better'n 30,000 km of tire life & the Kumhos (at the right pressure) stick like the proverbial to a blanket across the fairly broad range of conditions that we often encounter here in Oz too.

Up the back right now, I'm running a 205/65R15 Michelin for much the same reasons.... but don't let whatever tire/s
I'm running up front or on the back at any given instant put you off anything else too much; cos due to my rather broad ranging background & employment history, I often get asked/invited to test various tires &/or vehicles, and
sometimes I even get paid for providing my 'expert opinion' on them; 'x' being an unknown quantity & 'spurt' being a.... well, I'm sure you get the picture anyway!

So I frequently get to run a set of 'evaluation tires' for maybe 1,000 km up to as much as 5,000 km or so; which means my Kumhos have stretched their current 'more'n 30,000 km' out over a few years, cos they've had regular rests & breaks while I've run something else for a bit & worn out a set of someone else's tires at someone else's expense! :thumbup:
Seriously tho, just about anything from a reputable & well know tire manufacturer in a size that fits your Spyder & that has load & speed ratings that meet or exceed those specified on your tire placard is very likely to work better than some of the OE Spec Kendas, especially if your OE tires are more than just a couple of years old, cos they have been doing a little better of late. But almost anything else will likely be cheaper, more readily available, and far more forgiving on you, your machine, and its suspension,
if you run them at or near the right pressure for the (fairly light) load your Spyder places on them!! So I reckon it's fairly safe to choose your a/mkt tires based upon their stated performance characteristics & whatever
your 'identified needs & wants' may be!! Altho I absolutely
loved some of the 'sporty' or 'hi-performance' tires I've tested cos of their phenomenal traction, I'm not running them as my 'daily tires' cos I really don't enjoy forking out my hard earned for even the stickiest of tires every 5,000 km or so/3 or 4 times a year!! :shocked: Especially since, just like the Kumhos & now the Michelin on the rear, the Continentals I tested worked
almost as well as the much more expensive/sticky tires but because they're a bit harder compound & take maybe a minute or two longer to warm up properly, the lot of them work very well for my 'on-road' ryding and last a helluva lot longer to boot!! :thumbup:
