Author Topic: 35 Max PSI. What does everyone usually run?? (Read 3560 times)

Have snows with max 35 PSI. Was thinking of running them at about 32 PSI.

Any thoughts. I'm trying to get max life out of the tires.

Thanks

I run 30 to 32 just about all the time.

I run what the sticker on the door jam calls for. 32psi. Is that not the rule or can you play around a bit?

The recommended pressure is 30 psi front and back for my vehicle. However, the Kia dealership and my regular tire garage both have my tires at 30 - 33 psi or so.

I find that pressure range to be acceptable so I maintain it. Again, I make sure all 4 tires have the same pressure whether they are winter or all season.

My wheel (which is different size and brand than the one that came on the car) says max PSI of 44, so I try and keep it at 42.

Sir - I think you should be going by the vehicle rating for air pressure on the door sticker; not by what the tire says is max. pressure. I've never heard of anyone running 42 pounds on a daily basis. Must ride like a chuckwagon...

Sir, I ran 40psi on my Subie's new W300 IceBear from TireTrends when the door jam says 32F/29R. I drove it 650kms and found that fuel economy was better than EPA mileage ratings and steering was light BUT ride was harsh. That night I couldn't sleep well as I still feel the vibrations on my skin from the 7 hour trip. It's like sitting on a massage chair for a long time and after getting home, I still feel them all over. Not pleasant at all.

Now I run 35 psi (as recommended by Morty and Saffy). Ride is a whole lot better.

I also read somewhere a simplified guideline for us regular drivers... "it's better to have your tires 3 psi overinflated than under" when the temperature drops from 0 to -15C, our tires loose 3 psi. The extra 3 psi added a while back gives you reasonable buffer to keep you safe on the road

Because my vehicles are all larger full size cars and truck with 15" wheels I run 36 to 40 Lbs in them all. I find a better ride and better gas milage on all 3 of them from doing this. I also find I get a little longer life out of the tires as well. These are heavy vehicles and hold the road very well at these pressures.

Same car as Crolly--door says 32/29, I run 3 psi over that or 35/32. I find running 3-5 psi higher than specs increases fuel economy and improves handling without a real penalty in ride quality. I just bought a used RAV4 as a second car and its tires are rated at 35 psi max but Toyota's recommendation is 28/26. I'll probably start at 31/29 and then go up or down depending on what I think.

35 all around for me during street driving. The winter tires' sidewall is too squishy. low psi results in sidewall folding. Maybe i should use the brakes when I turn....
