If you were just using rims and not tires you might get away with 24". Otherwise, you can put on whatever will fit with the proper tire size..... Here's a couple of sizes... 155 80R13 (stock on most) 195 60R14 185 60R15
Yes
if your geo's bolt pattern is 4x100
as long as the bolt patterns are the same
26R
don't know what size it is
13 inch
It depends on the year and wheel configuration of your metro. Most metros have a 4 lug 12 inch wheel design whereas the Prizm has a 4 lug 13 - 14 inch wheel base. They may fit on a Geo Metro Convertible or any Geo Metro made after 1995 because after 95 the metro had 13 inch wheels. I would check by direct comparison first.
Can you swap a 93 Geo metro manual transmition with a 95 Geo Metro
It depends on the size of your engine.
155/80R13
6 3/4
If the engines are the same size then yes (ie) 3 cylinder 1.0L to 3 cylinder 1.0L.
