15" speed rated tire ?

[R67Chevelle]

Heres my second post so lets see how this goes. On my 67 chevelle I am going 15X10 rear and 15X8 front weld racing draglites. I have always liked the 15" look and even though 17 & 18's are nice I really like this look of wheel on my chevelle.

Now heres the tough question. I have had 295/50/15 & 225/50/15 BFG's which I dislike the ride, performance, and its low speed rating. I was wondering if any tire manufacture makes either a Z rated tire or simular speed rating, high performance tire in this 15" sizes. I have tried as many sources as I know of, so any advice would be greatly helpful...

Also, I have emailed BFG and goodyear about this situation without any responses... Thanks...

my person expierences with weld wheels drag lites and pro stars pretty much suck for anything more than drag racing. the wheels seem to flex when pushed hard through corners(270* freeway on ramps are the most noticable) kinda like the sidewall roll over when you are thrashing on a rental car. they work GREAT for drag racing...just dont have the side load strength for cornering.

toyo proxes has some 15" sizes zr speed rated, dunno how wide they make.
