Did I choose the right tire?

[Snake Eyes USA]

Hello All.

Truck is finally close to being show and road ready.
The current pictured Michelin Wide-X have to be replaced. Though new, truck sat in warehouse for a decade and tire walls have cracks in them.
Replacing them with BF Goodrich Radial T/A 275/60/R15. Did I make a good choice?
Its either that size or size lower of 255/70/R15.

Which would you have chosen for this truck? Really like how classic the BF Goodrich Radials look.
