Tire Pressure

[Glen Baker LLC]

I have three good gauges. Would one more make a difference ?

All different readings.

of course.

You have four tires, don't you?

I have several different tire pressure gauges I use and none of them agree with each other.

Solved long ago.

NASA had multiple identical computers. When they didn't agree, there was an additional computer of a different design whose decision was used.

Chinese tire pressure is way off compared to our PSI.

That's due to poor nutrition.

The average Chinese pound is simply smaller than the average US pound which ate better as a child, so you need more of them!

My Mav was delivered with 44 psi which is what the factory sets it at. The dealer didn't catch it during the pre delivery inspectio

My understanding is that they are deliberately shipped at a higher pressure than is desired for driving (to help stay round while idle in the train?).

Mine came high, and the dealer missed them, too.

My 18v Ryobi and the Maverick agree on what 36 pounds is, so I figure I'm good there--the Ryobi stops inflating at the set pressure, so I know they're all the same if done cold.

I'll note that when I measured on my '89 Crown Victoria, there was about a one degree difference between the amount pressure increased between front and rear (I think rear was more, but don't hold me to that!).

Also, on that particular vehicle, ford's indicated pressure was woefully inadequate! I think it was 30, and the car was all over the road. I forget what pressure I finally settled on (I want to say the result was 37 front and 38 rear when hot),.

As a generalization, mileage will be a bit better at higher pressure, and grip better at lower--but that car seems to have been an exception. As pressure is increased, the central of the tread bows out a bit more.

FYI, the Ryobi inflator (tool only) is on sale at Home Depot today,,,,,,

$20 @ Home Desperation, works great, I already had three 4 AH batteries,
This pic shows the 2 AH battery.

The 4 AH battery could easily fill from flat all four tires on a single charge.
I carry a 12v plug in under the back seat for emergencies in the field.
