I was in Costco yesterday, and popped into the tire shop to inquire about some PS4S. The guy said they still had fronts (19" $250) but no rears as that product had been discontinued. Really?? Doesn't seem like they have even been out that long... Tire Rack has them ($271/$314, $70 rebate.)

Maybe they are confusing them with the Pilot Supersports?

Bought a set just a week ago without any problem...

PS4S are too new to be discontinued. It is likely Supersports that PS4S replacing are discontinued.

Still readily available on TireRack

Ah the old, they have been discontinued, buy these instead dodge.

<Cue Monty Python Cheese Shop sketch>

That only works if they've stopped making all tyres. Except the one the cat ate, of course - "She, Sir."

stmcknig,
Aha, I bet that was it. He said they HAD SuperSports...
