Best Riding, Longest Lasting SC400 Tires on Stock Wheels

[moonunit]

Hi,

I am about to purchase a 67K mile 1995 SC400, and the seller said the tires seemed to have flat spotted.  Good tread everywhere, but has a vibration at speed.  Could also be tires need balancing also, but the old lady rarely drove the car.

In case I need to buy a new set of tires, what Brand and series of tires have given you the best ride and longest mileage?  I am 58 years old, so I am not going to be drifting the car or driving the car in excess of 120 mph for any length of time, so I don't think I need W rating or higher.

I have had good luck with Michelin, Yokohama, and Bridgestone tires. What is the concensus among you long time SC400 owners?
