Too small should be 235/75/15

63 I think was one of the years that had the odd wheels and really tall and narrow tires?

Too small should be 235/75/15

I have a 1963 Six-Window Sedan de Ville with those size tires on it. They rub the insides of the wheel wells when the car is turned too far. I probably should have used 225/75R15. But this is a Fleetwood, so I would imagine the size is larger.

The big problem with getting the correct size of tyres, what using the tried and proven conversion calculators is that one has to remember that these older cars were built with Cross Ply tyres, and even back then, the early Radial Tyres were very narrow.

Modern tyres are fatter in cross-section, and lower in profile, as they are designed for what the factories are building now.   Very few makers will build parts for the older 'Vintage' vehicle market, as there is really not enough profit.

One has to learn to not turn the wheel as hard so as to negate the rubbing when using these supposedly correct sizes.

One thing to consider is how worn out the rear suspension bushings may be. Even new rubber ones can flex quite a bit. Looking under my '60, I can see where rubbing has occurred on the frame and brake line mount. I'm in the process of changing to all urethane bushings in the rear. Some sort for sway bar and or anti-roll bar is another idea I'm kicking around.

225R75/15 is probably going to be the best size in a radial.  You might talk to the folks at Diamondback Tires about their Auburn tires.  They are radials but built to look more like bias-plys, not inexpensive.

I'd like to thank everyone for your help. Tomorrow I will find out if I have one or more tire(s) have a flat spot and if some how it can be fixed or removed and I'll go from there. Thanks again guys.
