I bought a pair of US Royal 670-15 tires for my skinny Cragars thinking they'd be 27.5" tall like it says on Coker's website. They're more like 28+, which I think is too much for a Nova, so now I'm looking at 560-15 tires. Which would be more period correct for 70-72, US Royal or Pro-Trac? I like the pie crust of the US Royals, but the Pro-Trac for sure looks excellent on Cragars.
