I believe there is a sticker on the drivers door (near the latch) with this info, also it may be in the owners manual.
30 Front, 26 Rear
The recommended tires and tire pressure is listed on the Driver side door frame of the Fiesta.
32 front 28 rear
33#
That's your LOW tire pressure warning light in a 2002 Ford Windstar
215/70R15
how do you release a spare tire on a 1999 ford expediton xlt
On a 1996 Ford Windstar : Open the drivers door and on the latch pillar ( or the end of the door ) you will see an information sticker . One of the things it shows is the tire size on the vehicle from the factory
40 at the front 36 at the back
32 front 28 rear
Try tapping the drum
There should be a sticker/plaque on the driver side door with vehicle information including recommended tire inflation pressures for front and rear.
