I was looking at some car stuff on youtube.com the other day, & an add from Fitment Industries came up. They add gave off the impression that their inventory is quite large.
A lot of 14" aftermarket rims seem to be 6" and wider. Aftermarket 5" wide tires almost don't seem to exist, and 5.5" wide tires aren't that common either. In most cases, Mirage owners seem happiest with tires in the 155 to 185 wide range. 4.5" wide factory steel rims surely works on tires in the 145-175 range. In general, tire shops would use these guidelines -
Rim = Low/Ideal/High
4.5" = 145/155-165/175
5" = 155/165-175/185
5.5" = 165/175-185/195
6" = 175/185-195/205
6.5" = 185/195-205/215
I realize some people mount tires outside these recommended ranges, but they are still a good guideline to consider. I'm not really into aftermarket tires all that much, but I know some forum members are.
Fitment Industries offered 15 different 14" x 5.5" rim options that would work on a Mirage. Now a couple of those options are black steel rims, but 15 options isn't bad. Tirerack.com for example offers one 14" x 5.5" rim option.
If you combine 14" x 5.5" & 14" x 6" rims, 39 options come up for Fitment Industries. Tire Rack by comparison offers about 17 options.
I am not stating who carries the best wheels & prices. Those who are shopping for wheels can determine that. I just happened to notice a better 5.5" to 6" selection, & prices do appear to be competitive. Free shipping & mounting is expressed by them. I didn't explore or compare 15" wheel option.
Personally, I've thought 5" wide rims would be perfect for most Mirage tire applications, because narrower also mean less added weight. 5" aftermarket wheels don't really seem to be out there, however. Thus, 5.5" seems like a good place to start before shopping for something wider. If you really want a particular wheel, however, you may need to go with 6" or 6.5" wide rims.

I am just sharing this as a resource for others to look at. I am not endorsing Fitment Industries. I never really heard of them before, but I'm not really into fancy wheels. Steel rims and hubcaps don't bother me.
This may be old news to some, but maybe helpful to others?
