What size wheels & tires you run on 55 Buick?

It is time for me to order some wheels and tires for my 55 Buick. I am gonna run white walls but would like to know what size tires and how wide works well on this big ol car. I am using the Scarebird front disk brake and have Fatman 2" drop spindles and new springs 1" drop for the front. I am getting ready to install a 4 link suspension with a 71 SKylark rear end. Your advise and experience on steel wheels and size and brand of tire would be appreciated.

 

I see this is an old post but what size did you end up going with?
