Replaced my RFT at the biginning of the summer with supersports

Running 435ix w 18s staggered.
I was running +3 PSI then what was recommended for RFT tires. I believe OEM RFT tires call for 32psi front, 35 rear....so I can 35 front and 38 rear when I switched to the supersports.

1st question...how many miles are people getting out of their supersports? My rears are at 6/32 already. What are other people who run the same tires in 18"s for psi?


2nd question...Ordering winter tires off tire rack....tire rack recommedned a square setup for 225/45/18. Prob going with WS80's as I live in upstate NY.
Since this is a square setup....unsure what psi to run with these particular tires in this size since it is not OEM sizing.

Any advice would be appreciated.

Not really sure about your PSS longevity question, but you should be able to run them at whatever PSI your driver side door says. All that information should be listed in the door jam.

I was under the impression that the PSI recommendations on the door sil are meant for RFT tires not radials as RFT tires have a stiffer side wall.

All I know is if I run my radial tires at 32/35...they are very squishy

I run my Hankook Ventus at 39psi.
