I haven't been able to find that info at Cooper. I found their 105 PDF here, -

But yea, not the info you've found. Do you have the link in history perhaps ?

The place card on the tire doesn't have a light truck specification or anything for that matter. I'm going to run chalk across the tread regardless, just wanted a good started point. I'll use the vehicle place card as start IF I can't find anything else.

Also if one of you guys get a chance could you tell me what your recommended tire pressure is for 265 70 17's is. I have the owners manual pressures but my trucks recommended pressures on the place card is unreadable. Want to confirm they match the owners manual suggested.

 

It started snowing here at midnight and we got 3 inches or so. Not too bad. Still only 15 inches for the year total. That is where it stops with the small amounts, I'm fairly sure. We have the biggest snow storm we've seen in many years coming thru starting tomorrow. Damn, I didn't want to move snow on Friday or Saturday, depending on when it stops. The weather bureau is calling for a mass accumulation of that white stuff.

Once it passes, depending on the Jet Stream, it's supposedly dropping into North Dakota or maybe over Michigan and move across to the East Coast. It's going to be a nasty bastage this time, for everyone it touches.

 

Here is one I saw last night. I'll find the Cooper one when I can get into my search memory. Currently doing a backup. This is about E range tires. The description says they have to put "at least" the pressure the door tag says, but with E range, the pressure necessary, is higher.

Unlike cars, minivans, and lighter trucks that often specify low air pressure, the heavier trucks usually specify very high air pressure. A common air pressure for one these would be 55 front, 80 rear, or 75 front and rear, or like the example above, 50 front and 65 rear. Since weight capacity is a simple function of air pressure times air volume, the higher pressure is necessary to enable vehicles to do their job. Since we are required by law to put this air pressure in, that is what we will do, (unless of course you want more). It is also important to note that even though you want to adjust the air pressure to your own liking, you should never put less air in the rear of a pickup.

 

Yea, they should run square. Higher pressure in the rear doesn't make sense to me unless your loaded. Thanks for that info AK, gives reason to research that further.

 

I really ought to have an admin change the title of my thread lol

 

Yes, to something subtle like, -

"BIG TIME BADASS 5.4L SWAP THAT RULES!"

 

Here's a E rated 16 from Ford, showing recommended 2001 pressures, listed on the door tag.

 

That's showing the rear axle as being heavier. Guess I was thinking with the rear axle actually being lighter (unloaded) the pressure would be less. Know what I'm saying ? Or am I not thinking straight about that?

 

That may be all well and true, but the tag is for the tires, not the axle. Everything I've found shows the same area of pressure when it comes to E rated tires on a Ford. I'll find that cooper place when this thing finally finishes, about an hour, or so.

 

Odoyle rules!
