Wheel size for mini-spare

[VinnyG]

I've got the standard 225x60/16 tires on stock 16x7 inch aluminum wheels with a mini-spare on a steel rim. Does anyone know if FMC used a special rim for the minis, or whether that is a 16x7 standard duty wheel with a tiny donut? The reason I ask is that I bought 4 ea. 16" P71 steel wheels that have decent tires mounted. The purpose of the purchased rims is to mount new Firestone Winterforce tires. I'd like to use one of the tires currently on those rims for a full-size spare. If the mini-spare rim is the same as the P71 rims, it simplifies the swaps: one of the snows goes on that rim in place of the mini, and one of the rim/tire units that I bought goes to the trunk. Otherwise I need to either come up with a 5th 16x7 steelie, or see if one of my aluminum wheels will mount in the truck as a winter spare (which just kicks this particular can down the road until Spring). Thoughts? Thanks!

The compact spare is on a little narrow rim. Want to say it's 16" OD by probably 3 or 4 inches wide.

Its just a spacesaver rim size only. I'd just pick up another 16x7 for a full size spare if thats what you want. They are $6.00 at my local pull apart. I myself have 20" Boss wheels on my ride and just keep the space saver for the spare.
