PSI on tires - what do you run?

[RichardH]

My tires are rated to 44psi.

My tire shop likes to load to 32 psi, but I prefer running closer to 40 on fronts, 38 on rear.

Any problems with this?

I prefer the way it rides with the higher psi actually. I don't think I'm effecting the longevity of the tire. My tires also have a 115 load rating = 2769lbs per tire.

I run 40 all the way around.

OK, so I'm not alone on this.

Just checked (inflated) all tires. 40 front, 39 rear. Like that 1psi will make a difference. lol. Maybe give me a little more oversteer (or less understeer) while running the corners.

Already had some of the Kobalt 24v tools, so picked this up today. Nice compressor. Set the PSI and stops at that point.



Side note, as always the batteries are not cheap, but Lowes had a special, free tool with purchase of battery kit (2Ah, 4Ah, plus charger) so picked up a 200ft/lb 1/2" impact for free, and grabbed a second battery kit for the truck and grabbed a free circ saw. Good stuff. I keep the impact in the truck and can blast off the lugs in no time.

I run 38psi all around. When I ran 40psi on the rears, I ended up wearing the center of tire faster. Running at 36psi (rated on the door), I had issues with the colder months where it would drop down to 32psi and set off the TPI. I have learned on mine that new tires ALWAYS means new TPI sensors. I have NEVER had issues, but re-using sensors in this truck has caused a nightmare for me in all the low-pressure indicators and then trying to find the malfunctioning sensor...always seems to be the passenger rear for me.

40F, 38R is as perfect a combination of pressures you can get

my tires have a max of 51 psi. i usually run around 42 psi. i don't like the squishy feeling of the tires at lower pressures. my tread wear at 45k miles is totally even.

I guess I'm glad (sort of) I don't have TPMS. I do a quick walk around before I jump in the truck and check fluids/PSI every week.

Thx, I'll watch the tread for uneven wear.

Agreed!

I drive mostly freeway and it feels just right.

Your tire shop clearly thinks all vehicles are Corollas.

You'd be well advised to never return there. 38ish for Prated (like yours) and 40-50 for LT tires would be reasonable on these trucks.

Agreed.

I always purchase my tires online, for about 25+ years. So I find a tire shop to do a mount/balance economically.

I see you are in SoCal. When I lived in Orange County I would always use Tucker Tire. They were great.

The shop I use here in TX is a large outfit, NTB. They did do a good job on the oil change (semisynthetic) when wallyworld (never go there again) could not get the oil filter off. What a wuss.

Look on the tire sticker on the drivers side B pillar. Am I correct in assuming everyone's Expy has that sticker? If you're running the stock size/type it'll tell you the proper pressure. For my '04 Eddie Bauer it's 35 psi. I'm thinking that pressure is for curb weight. I believe the 'max pressure' listed on the sidewall of the tire is for that tire at it's highest weight rating.

I just drove mine up from Florida (to New Jersey) and I didn't have a tire pressure gauge or compressor so I took it to a Wawa and put in 40 psi by the pressure gauge on the pump Wawa provides for free air. Assuming the pressure was close it was too much and made my Expy ride like a truck . . . oh wait . . . it IS a truck - sorta.

Yes, there is a sticker, but...

You are correct that max PSI is at it's highest weight rating. Probably other factors why Ford said such PSI.

I'll still go with 40F, 38R and watch the tread wear patterns.

Lol, I call it a truck, but it's actually considered a Sport Wagon per State Farm (and registration?, I'm lazy right now and don't want to walk out to my 'truck'.
It has to do with the rear cargo windows from what I recall reading somewhere a while back.

40 - 42 psi

 

[gtnator]

I go 2-3 PSI below max

I run mine at around 32, but I live two miles from work and I drive on trails every week or two.

 

[ManUpOrShutUp]

My tires are rated at 44. I run them at 42.
