You can't go wrong with Avons, if you can find them. I run 8.5 wide 15" rims on the front and 12 x 15" rims on the rear, shod with 215-60-15 at front and 295-50-15 at rear. Yes - in both cases that's wider than the recommended max rim width for each tyre, but they fit well and look great (IMHO), and my local tyre specialist, who fits a lot of tyres for race cars, had no qualms about fitting them.
