Checking spare tire pressure
New truck 2013 F250, I decided to check the spare tire pressure today and make sure the key etc...worked. Tire had only 50 psi from factory. My front is 60 and rear 70. So I took care of that.
My Question is....Why is the valve stem on the top where you can get to it with out lowering the tire? I've flipped the spare on another truck with no problems, has anyone flipped their spare or has information why not to?
Thank

I flip them down, my guess would be because of the very small chance road debris could hit and tear the valve stem off somehow with it down. It is good to make sure the jack works and run it up and down at least a few times a year though, so if you have to lower the tire to check the pressure that also gets done.

Curious as to why the unequal front/rear pressures? Mine came with 65lbs all around. Do you also have 20" rims with Michelins? With say 1500 lbs of weight in the bed how would you run them? Thanks in advance.

With the wheel flipped the wheel will hold water and rust. If your flushing the under side of your vehicle with water regularly (which you should) to prevent rust, there's a good chance water will collect in the wheel.

Now that makes sense. But...No road salt down here, don't go muddin and I don't have a boat, so I have never washed or had rust underneath.

The only real way to know about your pressure, would be stop by a truck scale, weight the truck for the axle weights and find the load/pressure chart for your size tires.

edit: I do up the pressure in the rear for hauling and towing heavy weight. I keep my spare at 80 psi so I can adjust if needed.
