I purchased a set of Primewell tires (PS830 185/65 R14 86T) for my car ('99 Corolla). I’ll be damned if I can find the correct tire inflation specs for this tire on The Net (and I usually have strong Google Fu) or on the tire itself. No matter what I search on I either get directed to a site reviewing the tire or a site trying to sell me the tire. WTF?! All I want to know is what the proper tire inflation is supposed to be. Why is this so freaking difficult?
Look on the sidewall.
Look on the inside of your door?
30 PSI all around according to this site.
But Rick, how do I know that the tire adheres to this sites recommendations?
42
Are there any modern tires which can’t handle 30 psi? I doubt it.
PastTense. That is not what I am asking. Please see Post # 5.
According to Primewell’s website you get the correct pressure from your vehicle:

In my car it’s inside the flap over the fuel tank.
Not sure I understand what you are asking.
When it comes to inflation pressures, the car maker makes the specification, not the tire maker. The car maker’s recommended inflation pressure is a cross between the best handling, longest wear and best ride. If you want slightly better handling, inflate the tires to the car maker’s optional pressure (Listed on the tire inflation label usually on the driver’s door jam, the glove box lid, or the fuel filler lid) This will specify a pressure a few lbs higher than the standard pressure.
You can have two cars that use the exact same tire and list different pressures. On one car the inflation pressure might be 32F 36R and on the other car the pressures might be 34F and 34R. This is OK.
So, “don’t ask”, you are saying I do not appeal to the tire manufacturer but rather the auto manufacturer, yes?
Yes. Here is a list for all Toyota models.
Look at the sticker in the door jamb. It’ll indicate the pressure the car manufacturer recommends. The maker of the tire is immaterial. They don’t know the details about what vehicle the tire’s going to be installed on. And definitely don’t pump it up to the pressure indicated on the sidewall of the tire. That’s the maximum the tire is designed to handle. It’s not the tire manufacturer recommending it as the best pressure to run at.
AH! Auto manufacturer, not tire manufacturer. :smack: Ignorance defeated. Thanks to all.
This information is usually in the owners handbook. Most of my rigs have that in the glovebox.
