Yup Michelin tires are higher quality than most other brands. Does matter where they were produced aka what country though. The US and UK ones were very good. As you say Michelin tires seen to harden up long before you can wear them out. They also work poorly in winter climates not that our cats get driven in the winter. I also wanted white wall Michelin's but they are no more. One thing I have noticed with radial tires is they do not like sitting for a long time as they will end up like eggs. Old bias ply tires would go back to round after being driven. Sure your not supposed to leave the tires on the ground when storing your car but up north where I live the end of the season is too unpredictable.Just last fall I put 205/70R14 Uniroyal Tiger Paw white sidewalls on my '68 standard. They are pretty decent tires for the money. I tried to get a set of Firestone white sidewalls in the same size, but they don't make them any longer.
I wish Michelin still made whitewalls...I replaced a 15-year old set just because the rubber compound had gotten hard, which made the car ride roughly and bounce a bit over bumps. I have Michelins on all of my other cars and they are the BEST!
And, lastly, cj750 states, as long as your front end is aligned properly, you will definitely enjoy the ride.
