I always thought snow traction will improve with lower PSI? But again we have a snow day once every 10 years, sleet maybe once every 3 years.quote:
...Nevertheless, I prefer a bit more pressure to get better fuel economy, tire wear, tire durability, steering crispness, wet traction, snow traction and only give up a bit of ride harshness.
There are 2 situations:quote:

Higher pressure increases the overall stiffness of a tire. That reduces the wear rate. The shape of the tread of a radial tire is relatively insensitive to pressure increases, so the net effect (IMHO) is that a bit more inflation pressure improves the wear rate faster than the distortion of the tread leads to uneven wear.quote:

I used to run higher than OEM (+3 to +5 PSI) in my patrol cars. I would usually wear the centers due to the high speed driving. I run a +3 at x degrees set up now and have very even treadwear. I currently have approx 25K on a set of Goodyear Eagle F1's and expect to get 5-10K more using this "formula".quote:
