Cold weather tire pressure
 

I am curious to which tire pressure i should be at. Car seems to slip a bit in the cold. I live in illinois and it is now winter.
Drive a 08 acura tl type s with yokohama avid envigor tires.
Tires are like new and my current pressure is 36 or 37.
Max psi on tire says 40.

What should i be at and am i to high?

what does your door placard say? is the psi you give the COLD tire pressure (ie first thing in AM)? what size tires?

IIRC, cold tire psi for your car should be 35 in the front and 32 on the rear.

thanks and it is about 37 psi cold. Tires are stock for my 08 type s. 17 in rims. Do most people always put more air in front and less in rear.

I would just follow the psi amount posted on the door sticker. I find that when I keep it at that and drive around the psi can go up 3 psi.

sounds goo thanks but should i have more air in the front and less in the back? Or same all around is good?

fronts should have a little more since the weight of the engine changes the tread profile I'm guessing. More air to compensate.

You run less pressure in the rear to aid in traction since the rear is lighter than the front.

Those are the best posts I've read to explain why the OE pressure recommendations are they way they are.

Since tires require various things as they differ, it is always a good idea to look at the tires on the car rather than check the information on the door of the car.

With a maximum PSI of 40 on those tires, your cold tire PSI should be ~32. Typically, warm tire temps should be ~80% of the maximum PSI.

As mentioned before, some run less pressure in the rear for navigating snow/ice conditions, but that's up to you.

thanks for all the help I went with 35 and 32. I might bring down the fronts 3 psi or so. This is what car reads right when i start it. COld start and temps are about 20dg around here. Hope it handles better.
