I liked the Shinko 777 the one time I had them on my '86. They rode well and gripped in turns. The rear lasted as long as any lower priced rear I ever ran.
I am running the Nexen SB802 on the rear of my RSV now. I have found the horror stories to be so much urban legend fodder. The tire works well in every aspect for me.
We also have Nexens on Kris' car. So far, we are happy with them in both applications.
