What tire PSI are you using
 

I've noticed it doesn't take much to get the tires on my FR-S howling in a turn. I'm curious what tire PSI other people are using. The max for these tires is around 50 PSI but my dealer had it at 32. I do think the noise is a function of the tires rolling under, not a lack of overall grip. Anyone arrive at the perfect pressure yet?

It looks like 45 PSI in the front, 42 in the rear is a good combination.

Explain yourself please.

Personally I think the tires suck for grip and I think the noise is likely a function of lack of said grip. Feel free to add more air to try and get them not to squeal. IIRC mine were around 38 psi all around when I picked mine up, squealed badly any time I cornered hard. Stock tires are off the car now (less than 2 weeks after I bought it)

I've run the stock tires for the past couple of auto-x's .38-40 lbs might be ok for the fronts, but the (stock) rear tires seem to want more like 33-36lbs. More just rounds off the tire and makes for more fun than speed. Take this as what it is, though - one guy's very narrow scope of experience.

I knew the stock tires had low grip, but I was surprised how easily the broke loose and made sound. I checked the tire pressure yesterday and the wheels were at 31 psi. The recommendation in the door is 35 psi. I am surprised Subaru delivered the car without adjust tire pressure to the recommendation. Anyway, I set the tire pressire to 36 psi. That helped on the tire noise and the steering feels a little crisper as well.
