While doing some browsing on Tirerack, I noticed the S04 was available in OEM sizes for our cars with 20" wheels.

A little less grippy, but rides better.

Are PSS worth the $400 premium over the S04?

 

I had S04s on my 350Z. They are great for maybe 5000 miles. After that they suck. Just my 2 cents.

 

what issues were you having?

 

I'm considering them as well since the PSS are backordered everywhere. Reviews seem to be pretty good, always ranked just behind the PSS.

 

PSS shows available on tirerack right now

 

Tire wear was just terrible, and as they wore road noise constantly increased...

This WAS on a lowered 350Z, and the rear camber could just out of spec. (Adjusted as much as possible back to spec)

They may be fine on an F-Type.

 

PSS have significantly longer tire life, and better performance. So if it was me buying, I would get PSS without hesitation (and I have).
