I couldn't get the Goodyear racing Eagles I'd hoped for.They are no longer in production in the size I needed for the 2-wheel axle.
The 130-Club rule book requires at least an H-rated tire to run.And I can run as fast as 138 mph with an H-Rated tire,which is the theoretical top speed of the truck with the trailer,if the composite Cd ends up where the physics suggests it will be.
Going to a single motorcycle tire is the only option I have in order to preserve the trailer body and get a speed rated tire underneath. The larger diameter will intrude through the floor and into the interior space.Not 'practical' but one way to get a top speed without completely re-engineering the trailer.
Knowing the top speed will allow me to reverse-engineer the composite drag coefficient,using Hucho's 30% delta-drag/10% delta-top speed relationship for a comparison to the mpg-derived Cd.
After I've got Bonneville behind me I can restore the original axle and wheels for 'normal' duty.
