165/65r14 (factory size 14" tires) - Walmart offers 17 options tonight (some may be duplicates, however). These are 22.4" diameter tires.
175/65r14 (14" tires, 23" diameter, only +2.7% variance) - Walmart offers 113 tire options tonight, & this is why some members consider this size. These tires are obviously slightly wider (10mm).
185/60r14 (14" tires, 22.7" diameter, +1.3% variance) - Walmart offers 76 tire options tonight. These are 20mm wider than factory tires.
You seldom hear anyone have issue with any of the three sizes I listed above. According to tire experts, anything within 3% variance is considered an acceptable change. Thus, the three size above are quite safe to consider in my opinion.
Some members with 195+ wide tires have reported tire rubbing issues.
I personally like 165/65r14 tires. For me, it's part of the Mirage's charm. I prefer narrow tires on small FWD cars, especially during the winter months. If I didn't have to deal with snow, I may be more inclined to use the other sizes. For now, I am content with the 165/65r14 tire offerings.
If I don't like my pair of new 165/65r14 Kumho tires, I would be content/happy getting another pair of Nexen N'Priz AH5 tires. I would like to try the 165/65r14 Vredestein Quatrac 5 tires offered by Tire Rack some day, too. These may be the best all-weather tire option, but I wouldn't expect them to wear as well as the Kumho or Nexen tires during the summer months.
As far as snow tires go, Nokian Nordman 7 or Dunlop Winter Maxx 2 tires will get the job done. Federal has offered a 165/65r14 snow tire in past, too.
