Nascar Drag Long

I can't find anything using simple web searches like, land speed tires, or salt flats tires. I've tried the Goodyear site and many other sites, but can't find anything other than pro-grade drag racing tires or nascar circle track tires. I'm only in the idea stages of my project right now but, if my numbers are right- the project I'm planning to build could go over 300 MPH. I can't risk using ultra-high speed motorcycle tires even at there ratings. I don't know where to go or who to talk to because it's a very small feild of racing, that not many people are into. Bonneville salt flats-Blackrock mountains flats- long distance land speed racing.
