Yeah, most of them are for miata's, which is why you see the 225 width a lot with a 23-24" height. The 275/50/15's that are available won't fit up front either, unless you're doing your fenders dirt car style. And most are track only, they're not street tires by any stretch of the imagination.
Hence, the reason for this entire thread. DOT legal, actual street runnable 15" handling performance tires aren't made in a useful size for these cars. Which is why I run 18's.
As for the "short" thing, F1 cars still use 13" rims (changing to 18" this season allegedly). You can make a taller sidewall work for a handling car, it's simply about tire design. The only reason a 245/55/15, or a 235/55/15 or 235/60/15 doesn't exist in a 200 AA/A is demand and cost. The reason those shorter tires are available has nothing to do with a shorter tire handling better, it has to do with the demand created by all the damn miata's that are used on the track. And you're not gonna get a 25.5" tall tire on a track going miata.
