Hello all... went to check air pressure in my spare and found it is mounted with the valve stem up towards the floor resulting in no access. Lowered it and flipped the tire over so it can be reached ant time. Seems like a bad idea to not have access to spare tire air fill. What are the feelings of the group.
Maybe there is a reason I am not aware of......
Thanks

I did the same thing. FYI, your spare might not be balanced either. Mine wasn't, it is now, but don't know which year Expy you have and when they stopped balancing the spare. First Ford for me so maybe they never have?

I have a 2022 xlt, tow package, 20" wheels, 8 passenger triple black. I didn't see any balance weights.

Well, at least you know before it matters! Might want to do some searches on Ford lug nuts and decide if you like the idea of trying to change a tire on a cold, wet night with the lug nuts on your vehicle.

I added a hose to the valve on the spare and ran it to a location by the bumper. It has a shrader valve built into the hose and a valve cap. Simply remove the cap and check the pressure.

There you go! Might have to do that myself. Thanks for the idea.

Depending on where you live, it is good to exercise the spare tire system up and down. If something were to seize up, I would rather find out in my driveway rather than alongside a shoulderless Highway with no tools. It happened to my sister in law where she needed the spare tire, but it wouldn’t crank down on her suburban. I also keep my spare tire inflated to the maximum pressure on the tire sidewall. I keep a tire gauge in my car and I figure I can always let pressure out when I need to use the spare.

I noticed the valve up situation on my ‘11 with my first flat. Not a big issue for me as I always carry a 12V air pump along with better tire changing tools (sockets, breaker bar, hydraulic jack, etc). Having an extension hose, is not a bad idea though.

Im now thinking about replacing my factory spare with a 20” wheel and 275 Michelin tire matching what is on the truck (assuming it fits in the well). Ill need to measure and confirm it fits, but thinking it should, as OD of the factory spare needs to match the OD of the installed tires, even though the wheel and tire size do not.

Where did you get the extension hose? Mfg / Part #.

I included the recommendation to remove, balance and flip the spares as one of the new vehicle to do's in a previous post. 20 years ago I was in charge of the chassis manufacturing engineering at Ford for Trucks and SUV's. As a rule we did not balance spares on any vehicles. As with most automotive manufacturing decisions it was all about cost and weight. After leaving Ford I had to drive a new F150 900 miles on an unbalanced spare one day. I'll never do that again.

Robert. I have 2011 and 2017 Expy Limited's. Both are 20" wheels with 275/55 tires. I believe the spare wheels are 18" but don't remember the tire size. Can you confirm that the OD / runout of the spare matches the mounted tires and do you think there would be any issue installing a matching 20" wheel / 275 tire in the spare tire well of either / both vehicles?

The spare sizes have likely varied by year, road wheel size, and by MY. Check the size on your spares, plug those into this diameter calculator for the answer to your question (https://www.tyresizecalculator.com/charts/tire-size-chart-metric-by-rim-wheel-diameter). Don't be surprised if the spare OD is smaller than your road tire OD, that would be typical. As for stowing a spare matching your road wheels, it should never be a problem, the stowing areas are designed to accommodate the road wheel/tires for stowage after a spare tire use event. But, keep in mind that the wheel will be exposed to dirt, stone pecking, etc.

Robert, thank you for your response. My reasoning is I am now towing between our NY and FL house (1250mi) and would like the comfort of knowing if I get a flat, I can continue with a matching tire, avoiding stability issues caused by even a slightly mismatched tire / wheel combo. BTW too bad ford (and chevy) didnt provide a simple plastic cover for the wheel well. They could have eliminated the stupid one that needs to be removed to change the oil to balance cost. It would be a good aftermarket product.

One trick I used to do when I lived in the rust belt to keep the steel spair wheels from getting rusted past the point of usefullness was to put two opposing elastic vinal spair tire covers over the tire. You have to cut a "door" into the upper one to allow clearance for the cable and to reach through to disconnect the spare from the cable system. Then you "seal" the door with duct tape. It's a hassle; but, it kept the spare wheels in prestine condition. I don't do it now that I no longer drive in salt.

Interesting. Making me wonder if I could just cost the wheel in some rust preventative spray paint or coating.
It’s only a spare so don’t intend on using it often but also don’t want too much hassle on the side of a road if I need it in winter.
