For the Rostyles, I'm running 185/70-14s. They're just a smidge wide for that rim, but within the margin of error. The originals were 165-14s (roughly a 78 aspect ratio) and the 185/70s are pretty much identical circumference and will fit without rubbing. You could probably also fit the 175/70-14s. I bought Sumitomo HTR-200s from Tire Rack also. My impression is that it's best to buy from Tire Rack rather than someplace local, because since these are fairly rare installs, your local warehouse might be selling you some very old tires.
