Thanks Will, strangely I am struggling to find suppliers in the states - google redirects everything to UK only!
I will check blackcirces, unless it is in error - I ordered a set of PS4S for my BMW from Costco, and they turned out to be the standard PS4! So I put nothing past the realms of an error nowadays!
Try putting your browser into Incognito mode: maybe open File > New Incognito Tab , depending on your browser.
Mind you, I looked at Michelin's UK site, and they now list three 18" PS4S - I'm sure that wasn't the case a couple of months ago when I last looked.
https://www.michelin.co.uk/auto/tyres/michelin-pilot-sport-4-s215/35 ZR18 (84Y) XL
225/40 ZR18 (92Y) XL
235/40 ZR18 (95Y) XL DT1
apparently XL = stronger sidewalls, and DT = longer life, from deeper tread
So ever so slightly maddeningly, standard Front 225/40 ZR18 92 (Y) is available, but Rear 245/40 ZR18 93 (Y) is not... one step forwards!
Checking Michelin in France (the mother node!) gives the same three sizes

Maybe there's a case for the Cross Climate Plus, which is available in the right sizes - if your use leans towards all-weather rather than mostly warm weather driving?
