Tire Inflation Question

[103]

I recently had mounted a set of Toyo Open Country A/T II’s in 265/70R17 on my factory sport 17 inch wheels. They are inflated at about 30 PSI right now (we have had a Florida cold snap, so they were at about 32 last week).

They look to my eye a little low, and most of the information I have found says not to inflate them past 35. Can any of you give me guidance on what PSI I should keep these tires at for street driving?

Hi Dustin,

Since these are not OEM tires the door label is of little value. It should be pretty easy to access this info on the Toyo website. Otherwise, call Toyo customer service and inquire. Maybe other forum members who have the same tire can also advise.

The side wall of the tire will usually say something like "Max load @ XX psi". I would say theres no reason to run it past that pressure.

Running at the max tire pressure will make the ride "Head Jarring" and im sure that is something none of us are looking for. I myself went to 265/70-17 and still run the factory tire pressure. The thing i noticed for tire wear and comfort is simple. Comfort has improved and the tire wear is good on all 4. Hope that helps.

Agreed. Thats the max load pressure for the tires. The op wants to put more in from what I read and I was saying thats the max that should be run for that tire.
I run about 32-33 lbs in mine. My factory tires when aired to max load psi can handle more than what the truck is rated for.

To OP, mine squat a little at 33 psi. Thats fine and normal.
