[Land-speed] Tire Pressure

[Rick Byrnes]

To add to JD's info, when I ran Michelin and BFG T/A  Z rated tires on the 
Merk, they (the Michelin guys) wanted additional pressure due to the weight 
of the car.  We were at 200 +- 5 MPH and at 4200 pounds.
I think I remember 60 psig was requested by the tire engineers.

On the topic of GY LSR tire, while researching for the Ford Fusion project, 
discussions with Goodyear engineers indicated that tire burst pressures were 
very very  high.  We ran 90 psig with a car that weighed 6000 pounds.  While 
the LSR 300MPH tire seems overkill for a car that only went 207, the load 
carrying capacity, and a huge margin of safety, made a seemingly risky 
venture a little safer.

I will run the LSR tire at 90 to 100 psi, depending on the strength of the 
wheels, ANOTHER big part of the equation.  I wonder what force will cause 
the rim to distort
Since most steel wheels use DOT standard rims, I will try to find design 
requirements before making another set of wheels for the liner.  (which i 
have to do)
