Recommended tire pressure: what psi do you use?
I've got an '08 Forester with 16" factory Yokohama tires/wheels. The door placard says 29 Front and 28 rear, with incremental adjustments based on load. Living in Minnesota with so many temp fluctuations, that's impossible to maintain, so in the colder months I've been keeping all 4 at 32/33 psi cold pressure to allow for extreme temp changes. Now, my dealer techs say they like them all at 36 psi cold pressure in the winter months, and on a sidenote they say they've discovered they get more even tread wear than with the factory recommendations. If you go from tech to tech, you'll get many opinions, and some say that 36 psi is way too high. Today, I added air for the first time in months, because overnights have brought my cold pressure to around 31, and with gauge inaccuracies, and more cold nights to come, I thought I'd try their advice. I pumped all four up to 36 psi, but this was after driving, so the cold pressure is probably going to be around 33-34.
I'm wondering what you all set yours at, and if a hot pressure of 36-37 psi could damage anything, like the suspension or anything else due to "tire hop."
I've only driven it one day that way, and most days my cold pressure has been around 32-34 throughout the whole summer. I thought it rode pretty well that way, but the slight increase today made every bump seem a little rougher out there. I'd appreciate your input,
