Recommended Tire Pressure?

[dandxg]

I was told my guys I trust at Discount Tire in Denver you should disregard the mfg. reco. psi of 30 and go with 35 psi on all of you cars. Reason being is with every 10 degree drop in temp. you lose 1 psi so if you inflated you tires to 30 and then we get a brutally cold day you will be running too low.

They also said it gets better gas mpg and longer tire life. Ok, but when I talked to a guy at another tire shop he said no over inflating will have you riding on the center of the tire only and will give you less traction in the winter?

So what do you experts think? Reason I ask is because my Camry says 29 psi and my corolla says 30 psi, but I have been running both at 35 psi and the cars gets better mpg but they are rock hard and on a snow day it makes me think less psi would be better for better traction?

It depends on the tire, some need a higher pressure and some run fine with door sticker pressures. Play with what rides/handles the best. 35 front is fine, but 35 rear IMO is a little high, could lead to easily locking the rear brakes. I typically ran 35-38 front and 28-32 rear. I would run a little lower pressures if there was heavy snow on the ground to gain a little larger footprint, and run a little higher if doing alot of highway driving to get a few fractions better MPG.

Yes pressure does change with temperature, but you check it at least a few times a year right?

Whats on the sticker is the best starting point. Personally I use 34 front and 30 rear. Seems to work well for me.

Anyone who sees a pressure number on the sidewall and uses that- Go finish reading the message on the sidewall! That number is MAX pressure at MAX load.

I use 30 psi on mine
35 psi on heavier cars

I actually find that running 35 in the front and 30ish in the rear is best for my hilly/snowy/icy area. Especially for the snow around here, if you deflate the tires any more, sure the surface area would be bigger, but it would just slide around on these roads.

I run 28 on all four for the best traction O.O

I live in ice and snow country and I do slip, but once the car sorts itself out I don't afterthat unless I want tolol

I guess the terrain and my driving style kind of helps in dictating what I put in my tires. It works for me, and it's what my dad recommended me when I got the car so :P

I haven't had a problem yet in the past two years pumping almost max on the PSI. if my tire says 50psi max I go 46 psi all four cold. I get better mileage that way. Ive notice a difference every time I change my oil on time and rotate my tires + inflate them to my preference. I dont need the traction because it doesnt rain where I live and I drive considerably normal to point A and B. My car is a daily driver.

Ran 36 on the 14s all around (sometimes 36/34), now am running 38 or 36 all around on the 17s. The last set of tires I ran through in 205/45/17 had normal consistent wear except for a bit of extra wear from a rear alignment issue I already knew about.

Of course, heavy highway mileage (rest of this week and next has me doing another 2400) and handling-changing large swaybars mean I have to have a slightly strange setup...

If I ran nearly max pressure I would run into problems everyday on my way to work.

Most of the roads I use to get to work are winding back roads now covered with sand.
And when it snows I wouldn't have the most traction pad to grip with.
I try to run 28 degrees in the cold, and 33 or so when its warmer.


I still manage to get 35-32 mpg no matter how I drive, which I can't understand.
