51 Chevy Styleline wheels

Hey fellas, does anyone know what size tire and rims (bolt pattern)came on the 51 Styline's. I am thinking of putting them back on, and can't find any info on it. Also, if I did go to aftermarket wheels, what would be the maximum width that ya'll would go. It has the stock 10 bolt rear, and an 80 model monte carlo front clip. any help on this would be great, thanks.

 

It should be a 15 X 5 with a standard GM 4 3/4 bolt pattern.

 

Thanks
