You can't park here!

Autocorrect. I'm surprised there's been no yippee instead of you're so far today

 

Because as you deflate the tires the contact patch increases? If that's what you mean then you are exactly correct.

That is why farmers run low psi....sometimes as low as 6 psi in their tractor tires.....to decrease compaction in the soil. Also the reason they add duals to the tractors....to decrease compaction and increase floatation. Also the reason why a certain manufacturer of Strykers instructed the US Army and USMC to decrease tire pressure in soft terrain.

 

Regardless of your air pressure, 80,000 lbs over 700 square feet is 80,000 lbs over 700 square feet. That force is going to hit the road somewhere.

We're not talking about a tire sinking into the dirt. This is the damage your truck will do to that lot.

 

I never thought it would happen to me but this ain't no ####e.

I bob tailed into a diner a couple o months ago and parked in front....angle parked...took up two 4 wheeler spots but it was better than taking a spot away from a big truck I figured. On my way in the waitress met me at the door, "The owner says you can't park there. You have to park way over there with the other trucks." I said, "Tell your boss to EFF OFF".

I peeled outta that spot sideways in my 359 Pete with all 500 horses and left 8 black marks on the way. Then I mashed the brakes and stood that truck on her nose so that all 18,000 lbs was on the steers. I balanced it that way while I looked in the front window of the diner and blew the train horn. Stuck my head out the driver side window and told him call the federal marshals if he wants but I am still putting 100,000 psi on your asphalt Hop Sing. Yeee Hawwwwww!

And that's no BS because I am a rockstar and that's how I roll C'mon.

 

Actually it is the axles that touch the ground that distributes the gross weight of the vehicles and its contents. Tires merely spread the downward force (pushed onto the axle) onto 1 or 2 tires per side onto a contact patch or footprint which touches the ground.

Tire pressure has no effect on downward force on a single tire, however in duals, a low-pressure tire will cause the other tire to carry more of the load. Of which causes the low tire to flex more, overheat, and potentially blow out (that's how blowouts occur). But it is still the same downward force per set of duals as if it were a single. What tire pressure affects is the size of the contact patch. Low pressure, bigger contact patch and more rolling resistance; high pressure, smaller contact patch and less rolling resistance.

Didn't they teach this in truck driving school?

 

Where is the crack head emoticon?

 

tire pressure does play a roll because it influences size of the contact patch.

 

ONLY in the area under that patch. You still have the wrought of the truck pushing down on the entire section of lot. Having bigger feet doesn't make a 300lb guy any lighter

 

A tire inflated at 100psi pushing down with 1500 lbs is still going to push down with 1500 lbs if the tire is 80psi.

Yes the contact patch (footprint) with be different in size as well as the downward psi (weight/footprint). But the differences will not be significant enough to matter.

 

300 lb guy leaves deeper foot prints. Learned that from a John Wayne. Actually watched a 400 lb man pan handling for food leave foot prints in the hot asphalt as he walked to get his change from a Ford Excursion as it sank into the ground.
Dude give it up.
