The "sweet spot " is 30-31 hot...I put 26 to 27 psi to reach the sweet spot and adjust seasonally....
I have been doing this for 15 years now with great success

Like every other car, go by the recommendation of the manufacturer of the car. 30 PSI cold. 30 PSI cold in the summer, 30 PSI cold in the winter, 30 PSI cold in the wet, 30 PSI cold in the snow. The only time you want to deviate significantly is if you're at an autocross, drag, or track event.

Update.
Just got back from a long road trip. Tires were 30psi cold. Stopped at a rest stop after 200 mile run and check them. Outside air temp was 89. Tires were 34 to 35 psi.
Car handled well and pretty good ride.
Thoughts?

You hear tons of people talk about tire PSI at the track or autocross or whatever, and you see so many numbers you start to wonder, right? I can tell you a story: I was at the track a few weeks ago and once my tires hit 35 hot it felt like crap, because I forgot to adjust pressures for one session, but when I lowered it to 31 it was much better, which people with BFG Rival S tires say sounds right. But that story has no real relevance to street driving. The simple truth is really simple: the manufacturer of your car tells you to put it to 30 PSI cold, when the car has been sitting and ideally not in direct sunlight - adjust it when the weather gets significantly hotter or colder than before - and you will be fine. And you are!

Normal and expected to see hot pressure about 5 PSI over cold pressure, on a reasonable day and when driving like you're "commuting". You'd see a bit higher if you were canyon carving or whatever. That seems totally good for the street.

I run about 27-28psi cold in my rear 305/30R19 tires. Done that with a set of Michelin and a set of Bridgestone. Both pairs wore completely evenly across the tread surface. The PO was running 32psi cold and those tires had the centers worn to the wear bars with quite a bit of tread still on the edges. The front 275/30R19 I run about 30psi cold and that is working good too. With the PO's 32psi the alignment was also bad and wearing the inside edges, but the wear was inside edge worn and center worn so the 32psi was too high a pressure on the front too. The weather here usually isn't too hot relatively speaking and the tires would rarely gain more than 3-4psi when driving it. 31psi hot is working good for a 305 tire and around 33 hot seems to work for the 275 tire.

So is Utah. When it gets cold out, I have a hard time KEEPING 30 in the tires. The last couple of weeks, both times I took it out the TPS monitor beeped and said I had 25. But I try to keep 30 cold PSI on my Pilot ZPs year round. Seems to give me decent treadwear and good grip.

I ran PS2's until they discontinued the 335-18. Great, but expensive street tire, why not Super Sport, cheaper and better? I wish Michelin offered a 335 in 18". Always ran 32 front, 30 rear. Adjusted nitrogen,lol, at track events, tires get hot, pressure rises. My rear tire was a perfect slick when retired, so I believe those pressures worked out. Good luck and enjoy.
