How much would you pay for a modern tech 15" 60 series performance streetable tire?

How about an all season 15" 60 series tire with modern tread, 130mph continuous speed rating and they are actually round for under 75 bucks each?
I run these on my car and noticed a MAJOR improvement in traction and cornering.
Also heard (not verified myself yet) that they are rotatable side to side.
I was skeptical of course but figured I'd give them a try and really like them, as like I said they stay round:D and very quiet on the road.
They are made by Sumitomo Rubber. (6th largest tire manufacturer)
