What PSI are you running for daily driving?

My new truck came from the dealer with a PSI of 40, as well. Wonder if they are getting that message from somewhere.

Edited to add: I've got the same sticker as dilbert below. 30 PSI all around for my 2017 TRD OR with the 265/70R16 Kevlar Goodyears.

 

Mine says 30 PSI on the off road double cab long bed. Strange there are differences.

 

5 psi right now, soon to be 10.

 

Can't compare limited off-road use to daily driving. That larger contact patch is also going to generate more heat and make you more susceptible to blowouts and cause irregular treadwear. Doubt a few PSIs due to change in temperature really does much though.

 

im not talking about daily differences. im talking about setting psi in the summer and not adjusting in the winter. and the difference between mid day summer and 6am in the winter in NH i promise is more than a few degrees. with regular tire rotations i havent noticed and cupping or chopping of the tread. and tires dont blow out like they used to so that doesnt scare me. end of the day traction is traction. and id like a bit more traction in the winter and willing to sacrafice a mpg or 2 for it

 

You say you're going from teens to around 28 psi when warm, and the rule is roughly 1 psi for every 10 degrees....so you'd have to get your tires up to 80 degrees in 0 degree weather for that to happen, which is highly unlikely.

Snow is not the same as rock crawling... When you buy snow tires you're recommended to get a skinnier tire because on a surface where you have very little traction, you don't want to ride on top of it, you want to dig down in it.

When speaking to factory tires, reducing pressure to try and get a wider contact patch for snow is the inverse of what you should be doing.

 

By your logic then, a drag radial slick should do just as well in the rain then, yes? More traction!

Come on man...don't be daft.

 

meant PSI there and not degrees. My summer cold pressure was about 32PSI. Believe it was in the teens one morning and it had dropped down to about 25 and caused the nanny light to come on. Not really sure how much a difference those few degrees matter in safety, treadwear or added traction but I still bump it back up to keep it closer to the normal pressures.

 

Nitro and forget

 

lol. Not even touching that one.

 

• Nitrogen is a gas and is still affected by changes in ambient temperature (about one psi for every 10° Fahrenheit). Nitrogen filled tires will require pressure be added during the fall/winter months as ambient temperatures and tire pressures drop. Nitrogen is good but can't change the laws of physics

light comes on when one tire is lower than others. it certainly doesnt come on when they all drop equally. ok scooby, glad to know ive been doing it wrong. works for me. works for most everyone i know except my hypermileing tool of a friend who drives a prius with 10000psi at all times. its clear you live somewhere snow doesnt happen frequently or youd know that skinny tires help in the deep shit which gets cleared away relatively quickly and 95% of "snow"driving is on hard pack where i think the size of the contact patch does help.

 

ha not sure where you got that idea from. That day, 3 tires were 26 and 1 was 25 and was orange. At warmer temps, I've had multiple PSI difference due to one side being in the sun and never had it come on.

 

The tire placard pressure, adjusted for your size and load rating is 32 PSI.

 

When i leave work ill grab a pic. Guarentee mine are under 26 when i leave with no light. Het an orange box around low tire and a light if one is more than 1 psi difference from others though

 

Absolutely wrong.

Hmm..well...um...ok.... You wanna tell these guys they're doing it wrong?

 

How did you determine this? Just curious.

 

Not that i know about cold or driving in snow. I pretty much daily drove a rx8 for years, gotta know what the hell you are doing to drive a rotary sports car year round without TC or stability control. And never dinged it or got it stuck


See my rx8? Its behind the car with an antenna

 

Yup same here for the Nittos. Had em at 34 but when winter hit cold air temps the tire pressure dropped to like 30.... so I bumped them up to 36. The dealership will air them back to 34 in the spring when I get my next oil change.

 

Wide tires + low PSI on snow =spin out. This old Dodge could go through anything with skinny tires.

About 35 PSI year round should be good.
