Redline tires, who makes good ones and is it worth it?

Try DiamondBack Tires.
It's been a known fact for years that Coker tires can have issues, mostly their bias ply tires not being round.

I've had Diamond Back vulcanize a dual white pin-stripe on a set of new tires years ago. Perfectly circular around around the tires and still look good after a good number of years.
