What do you keep your cold tire pressure set to?

What do you keep your cold tire pressure set to?

37 to 39 PSI depending on whether the average seasonal temperature is rising or falling.

43ish ... keeping in mind that "cold" is a relative term here in Fla.

This depends on the brand and type of tire you have. My original Goodyear tires had a higher maximum pressure and therefore we kept a pressure that was actually higher than the maximum pressure on the Michelin Defenders that we now have.

I have OEM tires and was at 42 PSI in the 9 warmer months and 37-38 in the winter, but I got a second flat tire when I hit a rough spot in the pavement at 42 psi and I have dropped my warm month psi back to 38. I may have lost a mile of AER, but it is hard to say. I do think that on long distance days, I get around 46 or 47 miles of AER instead of 48 or 49, but the difference seems to be less on less efficient days. Or maybe I am just looking closer on longer AER days.

I keep the gen 1 and gen 2 at 42 psi cold (front and rear). 42 doesn't come anywhere near the max sidewall pressure of either set of tires. If I go any higher though the ride gets pretty bumpy. No issues with uneven treadwear yet. Regularly exceeding the EPA range estimates in both vehicles.

Been keeping mine (2016 Volt) to 40psi, but with the rough, unmaintained roads here in Wisconsin I've been thinking about dropping down a pound or two for a slightly smoother ride.

42 psi. When it drops to 38, top off. This way, it will never be below the suggested minimum.

Interesting how most people are ignoring the recommended pressue of 36, front and rear.

 

[Ls3miata]

38 for me. Not sure what I will use when the blizzaks go on in a couple months.

 

[wizard_of-ahs]

Settled on 41psi.

The correct answer to tire pressure, the meaning of life, the universe, and everything, as many here have noted, is 42.

When I rotated the tires (for the first time) a few weeks back, I bumped them up to 40.

They're noticibly louder, but I could care less (I'm used to it with my Cobalt's ZIIs which sound like A/T tires when new. Because grip).

This is complicated by the fact that the dash tire pressure display doesn't allow for altitude. I'm at 4000 or 5000 feet. When my display says 38, the tire pressure is actually 40. If it said 42, the pressure is actually 44 and it's starting to get scary. I keep mine at 38, which is actually 40 psi. I've had problems in the past with uneven wear at 38 or less.

My sticker says 38 lbs (2014)

That's precisely why I decided to put this question out there

Out of date info. That was the initial recommended psi for Gen 1, then it was changed to 38 by GM. I lost air pressure all the time at 36 psi. Moving higher fixed that.

This is a Gen 2 thread so the assumption is they are trying to compare tire pressure of the stock tire that comes on the Gen 2 which I believe is Michelins.

This is precisely my point that tire pressure is irrelevant unless you specify the type of tire you are inquiring about. Each is different. Gen 1 came with Goodyear and the sticker had recommended tire pressure of 38 PSI. If you change tires then the information on the sticker is no longer valid.

How exactly does that happen? Either you have a slow leak or not. If your tire is not properly seated on the rim, 36 vs. 38 won't make any difference.

Exactly. And for Gen 2 most cars only 2 years old still have the OEM tires (unless you're a road warrior, or threw away perfectly good tires for one reason or another).
