Question about the tires?

If they are going to go to Mach 1+ I would think those rear tires would not cut it. 
I always thought the rail type tire (skinny, hard compound) would be needed for speeds that high. Also interesting to note that they have not integrated vertical stabs with the wheel units (like Craig did).
But hey - I have not run at Bonneville either.

If you're referring to the rubber tires going Mach, then you are correct. The
rubber ones, which I believe the website stated, are original 104 tires and
used only for low speed runs. For high speed and record attempt they use
machined aluminium billet wheels. The ThrustSSC also used the machined
aluminium...alot of engineering study went into the solid wheels.
True, Breedlove's machine was a more attractive treatment of fairing-in
the rear suspension. There are few detail photos of the rear suspension the Eagle.
From what I've seen the assembly seems to be basically an A-frame, kinda
spindly, narrow and "dirty"...IMO..but I'm not an engineer, nor have I been to Bonneville.
I wonder what the parasitic drag numbers are comparing Spirit of America's
aerodynamic appearance versus the NA Eagle's design?

Rocket?

From what I understand, if they need additional thrust to achieve the desired
speed, they may resort to a liquid-fuel rocket similar to the one used on the NF-104
providing about 8000lbs thrust.

There was some comment in the Project Overview about logistics troubles of
transporting LPG, but the site was unclear as to what they would be fueling with
the LPG. Looks like they'll be using the LM 1500 and JP.
