Default PSA: For those that overinflate their tires a couple pounds

in dry conditions to fight potholes...please deflate to regular recommended tire pressures for the snow/slush we are seeing today. i had forgotten i adjusted teh tire pressure a little (39-40 lbs vs. 34-36 in my case). things were a little more squirmy today than usual in the snow...now i remember why. compliance is your freind. and also remember to drive your S4 like the front heavy car it is and pay attention to weight transfer. thank you.

Default RTFM - it expressly says to add 3psi per tire when running winter/snow tires.

So, the recommended winter tire pressure for a sedan is 39f/37r (up from 36f/34r).

Default and i'm telling you that pressure taht high don't work as well.

at least in my personal experience. then again, this is ocming from aperson that runs their summer setup as if he was carrying loaded car. also i find that tires that are more inflated take potholes better and if the rears have more pressure than the front, the car feels a tad more neutral closer to the limit.

Default Guys, guys, take it easy. This has been debated to death, with no real consesnsus that I know of.

Many argue higher tire pressures for snow tires because of reasons such as potholes and digging through the snow better too. Others argue for lower tire pressures because it allows the tread to grip icy roads better. As a result, I run roughly the same tire pressures year round.

The other argument I never got was whether you should inflate to the same pressure all around, higher in the front, or higher in the rear. I've read arguments both ways and never saw much of a consensus on that either. I flip flop back and forth trying different things but never really noticed a dramatic difference. I don't track the car at all and so probably don't push the car enough to the limit on the street.

Default So you are advocating a lower pressure in the winter then

pressure increases with heat, doubt the tires heat up much digging through snow, right? YAY, lower pressure is the weiner

Default Re: PSA: For those that overinflate their tires a couple pounds

i always run my tires at a pressure which minimizes wear and is usually the same pressure at which one gets the most grip.

if you run your tires over-inflated for potholes, or whatever other reason (not rolling off the rim), you are not getting full grip.

i run my snows a bit underinflated since they always seem to wear more in the center (softer tires maybe the centers get more wear on the highway?)

Default No, I don't think anyone advocates running low pressures continually in the winter...

...just that maybe during a snow or ice storm coming down a little from the 35-40psi that people might normally run may help garner a little bit of extra traction. Kind of the same principle I think as having nearly flat tires on a snowblower, that it lets the tread really grip.

But as I said in my previous post, I don't promote going up OR down with pressure because I've never been convinced one way or the other. Would be interesting to talk with an tire-design engineer or somebody like that about the topic.

Remember the friction circle gets smaller when it snows!!
