I have a '92 Metro that I installed 185/70/13 Toyo Spectrum tires on. It rides and handles great, aside from the speedo being out of calibration. There are some 13" wheels that will fit the Metro bolt pattern. I went to the local Les Schwab and had them match the bolt pattern, then purchased a set of their "snow wheels". They are plain rims, but will adapt the 13" tire to the Metro. I have put over 100K on the car with the 13" tires, and have not experienced any clearance issues. It would appear that just once in my lifetime, I finally made a good decision!
