I did some playing around with math, and I find that a 185/60r14 tire should be 1/4" (6mm) taller than the stock tires. 176/65R14 should be about 1/2" taller, and this is a VERY common size. I can get them locally for about $45 each. 175/60R14 will be slightly smaller than stock, less than 1/4".
The dealer I bought my car from seems to be selling four of the stock size tires, mounted, for $129 right now.
