What PSI are you running for daily driving?

I've got 285/70/17 and am curious what PSI everyone is running on their rigs for daily driving. Comment your tire size and what PSI you've got. I just had my 1st round of service done at the dealership and they bumped my PSI up to 40 in each tire...seems a bit high to me. Lets hear it.

 

34 cold on stock wranglers. When it gets warmer and pressure hits 37, it starts to get a bit rough. I wouldn't recommend keeping 40 cold in each tire, that's too much.

 

34 is what the decal on the doorjamb of my off road says.

 

That's more along the lines that I was thinking, first thing I did when i got home was drop them down to 35. This may sound dumb but does the PSI needs differ on tire size or is the factory recommended good for all based on the weight of the truck?

 

> What PSI are you running for daily driving?

All of them.

 

Mine are right around 28-30 on a 35" tire.

 

oe firestones. were around 32 cold when it wasnt stupid cold. now some mornings they are down to the teens before they get up to temp and settle around 28. i dont mess with tire pressure in the winter because i think a flatter tire with wider contact patch is wise when the fluffy stuff falls

 

I wonder if they changed by region or date? Mine says 30...

 

LT vs P series (stock tires are p series so door jam recommendation will be for p tires) LT tires usually require more psi for proper wear pattern.

 

Wow, mine says 30psi all around with the 16" OR wheels on the stock Wranglers. I'm running 33F/ 32R with FN 16x8 wheels.

 

285/70/17 ..... I run 37-38 psi and my BFG's are wearing evenly.

 

glad you asked 35PSI all 4

 

1.1 psi

 

Couple things:

1) There's no way you're seeing an 8+ PSI increase in cold to warm increases. A 40 degree change in temperature only nets 3-4 or so lbs difference.

2) You should be increasing the pressure in winter, not leaving it alone. http://www.tirebuyer.com/education/tire-inflation-pressure-and-temperature http://www.tirerack.com/winter/tech/techpage.jsp?techid=168

 

Or im thinking about one of the other 23 vehicles ive had. Id have to go look.

32 on General Grabber AT2's (265/75R16)

 

if 40 degree difference is good for 4 psi, why cant they go down 10 psi when the temp is around zero? link 1 states to keep recommended psi year round but has no explanation as to why you would and link #2 is blocked on work computers. where do you live? please tell me somewhere south of NH so i can laugh my ass off my barstool. lower psi=larger contact patch=better traction on uneven terrain. or should people be airing UP to rock crawl?

 

36 Cold on my Nittos
