I have been obsessed with tires and wheels for as long as I can remember. I used to just read the lists of tire sizes, that used to be in car magazines, trying to find rare and unique sizes. Now combined with wheel offset, they are fun mathematical "fitment" puzzles. They calm my brain.


You are talking about the new PS4S? No 17, that sucks! I am planning on trying them next, thought in a 18" size.

19" is the smallest diameter available in the UK.

Yeah, no PS4S in 17 or 18 sizes in all of Europe, even though supposedly Michelin is european brand. Only for 19,20,21, with wished normal sizes sold at US only (for now. I hope that maybe in spring things with availability will get better). Due size & weight shipping tires overseas + import charges will at least double the price, they are not THAT much better. What's available in common sizing in EU are non-S MPS4 ones, but from my experience compromise in them is too much moved to street, grippy, quiet, wonderful wet traction .. but easy to overheat on track, so not considering "normal" MPS4 anymore, as i need dual-purpose tire. As of now, "old" PSS or AD08R seems better choice from available here.
