Just put on my winters on 16's and am wondering what pressure to run them at. The 37psi as per the door sticker is way too high.
I'm thinking around 32psi would be appropriate. Anyone has any experience?
On what do you base the 37-is-too-high assertion? Somebody spent real time and money determining those pressures...they don't just pull them out of their butts. Unless you're going to much larger tires than stock, I wouldn't go lower with the pressures. Decades ago, "snow tires" worked on a "paddle" priciple, and worked really great...until their second revolution, when their tread was fully packed with snow. Then they would just spin. So, their performance could be marginally improved by running the pressures a bit low. That allowed the tires to flex a bit more, which helped them to eject snow that would otherwise pack into the tread pattern and stick there.
Modern winter tires don't work on that old "paddle" principle...they have thousands of little biting edges right out on the rolling surface of the tire. Added tire flex will not help them perform better. Whatever pressure value that will result in the flattest-possible contact patch will be the optimum pressure, and that is typically the same value as the recommended value on the door jam sticker if the winter tires are the same size as the summer tires. My winter tires are one size narrower, so I raised
the pressure a bit to restore their flat contact patch.
