Yes. They used to be called McCreary. They were the track tire at one of the bullrings I used to frequent and they are required for IMCA modified classes. If I recall correctly, they are predominately bias ply construction, although they may have radials by now. They grip good and have stiff sidewalls, so they are a decent handling tire. They do have d.o.t. tires for those classes that require them so you could legally run them on the street, although they will probably not encourage it.
An another one to look at is Towel City. Google them for their site.
