What do you mean by "work"? It will fit, but you may need stiffer rear springs to prevent rear tire rub. I'm running 235/60/15 on 15x7 at all four corners with no rubbing issues. The 15x8 (Corvette) rally wheels have a different offset that can make many tires rub.Will this combo work on a 69 coupe with standard suspension?
Murry...15x8 Corvette rally wheels have A 4" back spacing,
They will rub with any reasonable sized tire, unless you like the jacked look in the rear I would get correct back spacing.
