Since the first hot rod people have tried to fit bigger tires. As a replica, I get the flaw in changing the tire size but as you said, to each his own.

I am still on the fence.
First, tires back in the 1960's for Cobra's were small and terrible. Today's tires are light years bigger and superior.

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.
