sonyxperiageek: Why is the PS5 cheaper than the PS4 I wonder?

That link showed a Pilot Sport 4 S vs Pilot Sport 5.
The S version is generally a more sports orientated tyre so probably adds a premium to pricing. There is supposed to be a Pilot Sport 5 S, but might get a name change to PSS5.
I went through this drama trying to find PS4S for smaller wheels but had to get PS3 (no S).
I agree the Pilot Sport S 5 (and the 4S) is an ultra high performance tyre with less durability all things considered.
I think the Pilot Sport 5 is the same tier as the RE003 i.e. not as high performance but still a sporting tyre.
