Second, I remember some time back, David (or Tom) Kirkham saying that after extensively testing of their cars on the track at Miller Park, the smaller tires performed better. I forget the exact sizing, but I think for the rear they preferred the 275 size.

A larger tire may not perform better, and certainly for me, looks very weird on a replica of 1960's sportscar. And there's probably 0.0000000000001% of the Cobra owners who actually use their tires to fullest extent possible in order to squeeze every last bit of performance out of their car.

Just one person's opinion, mine, but fat tires are like fart cans, or even those really loud pipes on a Harley. Just for show and noise. Performance? Not so much.

I agree with most of what you are saying. BUT I think every Cobra owner tries to get 100% of the performance in a straight line. In which case bigger tires would help.
