Not necessarily. There is a big enough body of cars that use these sizes that someone will keep them in production, the way you can still get correct tires for most 1920s-30s vehicles. (Check out Dunlop's classic offerings sometime!)

Hell, you can still get TRX tires, and they only fit about four vehicles for two or three years, thirty years ago.

I’m still struggling with this one. Focusing strictly on sizes (not brands), it appears the consensus is either 255/60-15 front & 275/60-15 rear or 295/50-15 rear & 235/60-15 front.

What I don’t see is an agreement on which is better for a mixture of in town cruising & semi-spirited back county road driving (no track time).

Does a 255 meander/tramline when cruising?

Does a 235 under steer when pushed around a corner?

Does a 275 induce over steer too easy?

Does a 295 increase NVH?

Or is it all a wash and end up being a “whatever looks best to you” thing?

The tires will go on a Superformance with about 450-500 hp.
