Yet Another Tire Questions

I want a tall tire, something like the M&H racemaster @ 275/50-17 but $200+ is to much for my buget and I need tires now. The Nitto 555R 275/40-17 that I have now are well past there safe driving life. Does anyone know of a tall sticky tire or a place that is giving away the M&H's?

I have a MagnaCharger running 6psi right now getting ready to turn it up to 8.5 and add some water/meth injection that I have waiting to be installed so sticky is a must!

I am going to move to an 18x10 rear wheel but am having the same issue finding tires. Everything is low profile and I am wanting something with a circumference around 85-88 inches. Does anyone know of a tall, sticky tire out there that is this tall and not $225+ per tire?
