Hi all, I have a quick tire size question. For the past 5 years I've been running a set of original re-treaded bias-ply Firestone tires on my 1956 Pontiac Star Chief. They have served me well up until today when the tread finally blew out on one of the tires. So now it's finally time to upgrade to a set of Radials, but I'm kind of scratching my head as to what size tires to order. The Firestones are so old, all the say on them is 'Firestone Deluxe Champion 8.20-15 tubeless tires gum-dipped". So all I know is that I seem to have a 15" wheel, and not much else. Can anyone help me figure out what size radial I should be getting? And give some recommendations on what type/brand that is a good deal? I don't have a whole lot of money to spend, but at the same time I don't want to get complete crap. My only requirement is that I want wide (2" +) Radial White Walls. Other than that, I don't care about brand or anything else, and hopefully something that is cheaper than Cokers! Thanks all in advance!
