Spare Wherl
2017 F350 Platinum, spare is a steel rim with a different tyre than the rest.
Anyone else notice this? I would imagine that the spare should have the same rim and tire?
Stock Michelin’s on the truck (dealer didn’t change them)

In 4 decades of driving I’ve never had a vehicle with alloy wheels with a spare that wasn’t steel. I never went to the expense of buying a matching spare either. With the amount of dirt the spare collects riding under the truck it wouldn’t be pretty when I drug it out to use after a flat anyway.

How important is it to have the same circumference tire? I have 275/65r20's and the spare is 245/75r17 ? I would say quite a difference! Would a 20 fit the space allowed?

When both are new, the 65r20 has a slightly larger diameter. However when the 65r20's are nearing replacement, that 75r17 that has never touched the road will actually have MORE diameter. Your spare tire will never be a 100% match for the 4 that are on the vehicle, but it will be close enough to get you to a tire shop, and get the flat fixed.

Some of the trucks with chrome or alloy wheels came with steel spares that were not always the same size. Maybe all of them....?

It’s just the trucks with 20” wheels that get an 18” steel wheel and the slightly smaller AT tire for the spare.
Separately, IIRC, trucks with OWL road tires get a BSW spare.

My wife's F150 with 20" wheels comes with a 18" spare that's about the same diameter. Weird thing is her 2018 spare wheel is aluminum and is actually nice enough looking that I wouldn't object to having them on all four corners.
My F250 spare is the same model of tire but does not have the OWL and it is mounted on the usual steel wheel.

Regardless, a 31.5 " diameter spare isn't a good match for 34.1" tires.
