Thank you! Very informative! I definitely knew I wanted the 2 factory sizes, but didnít know about the other options that are easier to find!I wouldn't trust a used car dealership to suggest the best wheel/tire package. Unless you know what you want, I wouldn't even approach a dealership. You need to indicate what you are looking for in a wheel/tire package first. I wouldn't go into this without a good understanding of what you want.
Looking at what you have 205/40r17 -
205 is wide, & 165-185 are better (don't hear of rubbing issues).
40 is low profile (rougher ride), & 55-65 aspect ratio would be better.
17" rims are quite large, & 14-15" would be better.
Your rims also appear to be wide, but that's hard to tell in a pic.
I wouldn't go over 6" wide rims for a Mirage, & 5" - 5.5" may be better.
5" wide rims are recommended for 155-185 tires (these are not an easy aftermarket option to find, however).
5.5" wide rims are recommended for 165-195 tires
6" wide rims are recommended for 175-205 tires
Personally, I'd prefer 4.5-5.5" wide rims for a Mirage, but others do use 6" wide rims.
14" rims & matching tires sizes
165/65r14 (22.4" diameter) are factory size tires, but 175/65r14 (23" diameter) tires would give you more tire options. These are the two most commonly used 14" tire sizes used by Mirage owners.
15" rims & matching tire sizes
175/55r15 (22.6" diameter) are factory size tires, but 185/55r15 (23" diameter) tires would give you more tire options. These are probably the two most commonly used 15" tire sizes used by Mirage owners.
Aftermarket small rims are not as common/popular. You will have fewer choices/options than someone shopping for Corvette rims.
14" wheels may give you a better ride (higher profile tire)
15" wheels may give you better handling (lower profile tire)
The difference between these two wouldn't be that great, however.
I would shop on-line before approaching a local tire shop or dealer. Find something you like first, & see how close they can match that along with price.
Example of shopping on line for 14-15" rims that are 5-5.5" wide -
There are others like tirerack.com & discounttire.com. Just search for rims that fit your car.

Example of shopping for 175/55r15 tires -
Example of shopping for 185/55r15 tires -
These are examples. I used the same vendor to show the difference in selection when looking at different sizes. I would check out tirerack.com, discounttire.com, tires-easy.com, walmart.com, etc..... when tire shopping. Then I would see what my local tire shop can do for me. It's not a crime to be informed when shopping for something.
