What PSI do you run?

[Truckguy24]

38psi here...

Here's a question for you guys...

How often do you check the pressure?

 

[mblouir]

Not as often as I should. Probably once every month or so, unless one happens to look low.

I run my 30x9.5 R15 BFG A/T's are run at about 42PSI for daily driving... Been wearing like iron so far.

I keep forgetting to air them down when I go offroading... But when I remember, it'll be down to about 15 - 20 PSI

I don't think I'll ever run mine @ 35 again. The guys that installed my wheels/tires (RimzOneOnline.com) set them @ 45 when they put them on. My mechanic dropped them down (without me knowing) to 35 at the first oil change/rotation after installing them. I only realized it after a while because the outsides were wearing where they weren't supposed to, which is why I raised it back up.

I'm not arguing Toyo's recommendation as I'm sure there's a good zone one can be in, but I don't see myself running these 33" Toyos at the same pressure as the tiny tires on my mother's Camry (~1/2 the weight), especially when they start showing signs of under-inflation at that pressure.

Do what you think is best for your truck, and your wallet, but I'd also strongly suggest doing some serious research on places like tirerack.com and find out the truth about proper inflation pressures. Don't just take my word, or the word of someone else, look it up yourself so you get a better understanding of it.

Im not argueing with either of you and I respect your opinion.

It's just hard for me to think that Toyo would know less about their own product then RimzOneOnline.com,tires.rack.com etc.

e-mail from Toyo(varies slightly from the conversation I had with Debbie but, what she told me on the phone was parphrased in my o.p.)

Thank you for contacting Toyo Tires USA. Your new Mud Terrain Tire in
size 37x13.50R17 can carry a single tire weight of 2835 pounds at 35
PSI. Depending on the original equipment tire we would recommend either
30 or 35 psi. (on the phone she said 35psi repeatedly with the "maybe 2-3 varience")


If you would like an exact please provide me with the OE
(original equipment) tire size located on the vehicles door placard. (35psi )

As far as a pressure when towing or carrying a load we do not make
recommendations on pressure and would suggest your tire dealer weigh the
load and advise of an appropriate pressure.( again on the phone she said 35psi repeatedly with the "maybe 2-3 varience")

Please let me know if you need anything further.

Sincerely, Debbie
Toyo Tires USA

The people who put my tires on (Tires Plus) just told me on the phone 35psi and also referenced the vehicle placard.

Even with all the research I (at some point) have to listen to someone.

With the manufacturer and retailer/installer BOTH confirming 35psi (and referencing GMs placard) I respectfully ask why I should question them?

Toyo's # is 714-236-2080 Tires Plus(one locaton in Jax) # is 904-786-8560

Please don't take this as an "I told you so" but, a serious question. Perhaps Y'all know a different question to ask them that would garner a different answer for diferent applications.

as to the 28psi on a placard that's what caused problems with Ford/Firestone.(according to Tires Plus Ford wanted that as the recomended PSI NOT Firestone)

The important part here, that wasn't mentioned earlier (or I missed it) is that the tire was designed to run max load at 35 psi. What I said earlier though still applies, that once you change the size and/or load rating of the tires on the vehicle then the placard no longer applies, because it is information for a specific size and load range of tire only. You just happened to luck out and get a bigger tire that matched the same psi/weight range as the OEM's
