What size drag radials on 10 hole wheels

[85_SS_302_Coupe]

Do they make a 265/50/15? I've got those on my Tens, but they're just radials. They're nice and wide but don't bulge out like an offroad muddin truck or something.

Would the 275x50x15 change his gear ratio?

275/50/15 (26") is nearly identical to stock tire diameter (25.7").
