Tire pressure

[aldive]

What pressure do you run in your street tires?

How often do yo actually check the pressure?

 

[JDraper]

Depends upon what vehicle and checked once a week.

Explorer gets 28 PSI (On 33 x 12.5's)
Mach 1 gets 28 PSI
66 Mustang gets 30 PSI
O5 F-150 gets 35 PSI

 

[Donner]

Only have one street vehicle - never checked the pressure.

Yikes.

My explorer is running at 35psi. I know my dad's GMC 1500 is at like 60psi, and not sure what my mom's Honda runs.

 

[Donner]

That's only the ricer...

Yikes.

The Ex is diff, but the ricers, never had issues with their tires (except one years ago).

v v I do also, but I don't have streets on the Ex, run MTs. Pressure is checked 2x mo.

 

[aldive]

I run 40 psig all around.

Pressure is checked weekly.

 

[SkanlaxJMO]

35psi i check it evrey once in a while.

35 front, 34 rear on our '92 X (33" Trux mt tires).. checked at least every few weeks (more if I feel locker wiggle when driving)

33 psi all the way around on our '06 mustang (Pirelli p zero nero tires).. checked at least every 2 weeks

The other street vehicles (flat bed truck etc /trailers) get checked before I take them out (I don't drive them enough so they sit for a few weeks to a month between driving).

edit: change focus to street tires

Why should anyone check tire pressures in Explorer's? Everyone knows that Ford and Firestone have it all preset for you.

 

[Joe Dirt]

I remember the first time I read the factory doorjamb sticker with the original non-updated PSI for my Ex. Yikes!!!

I run 35 psi in mine.

40 psi in the ex, check it every 2 weeks or whenever I'm going to drive any great distance. Mostly in an attempt to squeeze a bit better gas mileage, but it handles a bit sharper I think.
I run 35 psi in the 5.0, and the same in the Breeze (s@#tbox)

35psi

You should run your truck at 35psi if you are driving on the street alot, but if your driving offroad youll be ok at a lower pressure. You dont want to have the pressure to high when u drive on the road or the middle of your tire will wear out faster then edges. If ur pressure is to low and u drive on the road your edges will wear out faster then the middle.

i ran my last set at 40 psi, no problems for the 75k miles they lasted, still run 40 psi in current ones, checked every other gas fill up

 

[MustangP51]

I run mine at 40psi, I check the tires every 2 weeks, Or when they look low

 

[Charlie]

I run mine at 35psi. Usually check about every month.

 

[Anime]

Using LT Michelin LTX M/S, I usually have them at ~42 psi, though it varies, sometimes I set them at 45psi for longer highway trips for mileage, or around 40psi for comfort, or in cooler weather when i know the pressure will increase later with warmer temps before I'll be checking and filling them again.

38 in the front, 35 in the back, for Firestone Destination AT's. This is for best tire wear for my work use. More than that wears the centers faster...

It's a decision between best fuel costs, or tire costs.

 

[MountaineerGreen]

I run 40 front and 38 rear in my 285's, they aren't wearing any more in the middles. I ran my 265 BFG's about the same, they wore just fine. I check them fairly often, I'd say once a month, never had a tire loose any air.

I came about this method by driving on a floor covered in fine dust. If the dust only sticks in the middles, too much. If not much in the middle and more on the edges, too little. Its a very precise and scientific method

So if you drive hard into the corners at bristol for 500 laps you should not have any extra edge wear, LOL.

Tire wear is not from a static condition of a vehicle. As weight is applied to the tires in uncountable conditions, rubber is worn off of the tires.

The best air pressure is that which gives even tire wear during the actual use of the vehicle. That means that my Father will never wear out the edges of tires, he drives too slow. While other people will always wear out the edges, they drive too fast in corners. If the alignment is bad, such as with way too much camber, no amount of air pressure will keep the inside edges from wearing out first.

Tire pressures should be different for every single driver and their vehicle. How each driver, tire, and vehicle is operated dictates proper tire pressures, not any odd method. Regards,
