With a clean body design the biggest aero drag is the wheels; you want the smallest that are safe for the projected speed.
Today they enter turn one at Indianapolis at over 200 mph. Before they changed the rules to slow them down, they entered turn one much faster.
Arie Luyendyk's tire are just the right size for going fast on pavement.
Every lap was a ?NNNNeeeewwww LLLLaaaaapppp RRRReeecccooorrd!!!? The result was an average speed over the four laps of 236.986mph, three mph faster than the pole speed set the previous day. His final tour was 237.498mph, which also still stands as the Single Fastest Qualifying Lap. http://www.motorsportretro.com/2012/05/indy-500-arie-luyendyk/If Puppy has ran sportscars and roundy-round midgets/sprints his driving driving experience is different than most Landspeed racers.
I'm used to climbing on the binders at 140 mph on pavement. I'm sure that Puppy has done that too.
At this point in my life, I have no interest in running Bonneville, been there done that (two records). If I built a car today, it would be for FIA Standing Kilometer record attempts. The problem is that 1.82 ? and a FIA World Record won't buy you a cup of coffee. Neither will $2.00 and a SCTA Record.
I'm interested in seeing what the O.P. ends up building.
