14" rim.....what size tire will work best

I think I would try to find some 5.5 wide rims then you could run a number of sizes. I personally like the 235/60/14's and had those on a set of small bolt rallyes on a 66 cuda and it looked pretty nice!! I dont think you are going to like the 4.5" wide rims but if thats all you have to use then go for it!!
