Yeh i can't get ps4 for mine either even though they sell SS for it.
Yep, but sadly, PS4S are not available in this exact size :-(
Two types are available. Pilot Sport 4 and pilot Sport 4 S. The PS4S are the dogs. The PS4 are ok but might as well get Goodyear ASY 3s cheaper.
Thanks. Looks like it's just on the more expensive sizes - 225/40/18 is "only" £40 off a full set of 4. Not terrible though and stills and cheaper than anywhere else I can see.
The code is shown on their website next to the tyres which can accept it - not sure if it's just this one size or others too.
