I had an order pending as of mid March with notices that the tires would be available July 4th, 2021. Summit Racing was the go to for this. I then received notice that the tires would become available in July of 2022! A phone call to Summit Racing took care of the cancelation and refund. My tires are still in good shape for this year but I do like to stay ahead. Blockley tires are still around so that will be my fall back.
Coker has a nice range of tires but the Excelsior line in the 4x19 size seems to have disappeared.
If anyone knows anything different I, for one, would love to hear it.
At this point in time I am non-judgmental in which is better or worse. The way I drive (semi-hard) eats up all lines equally.
