wider steel wheels

I was in your same position about a year ago. I ended up buying 195/75 tires because that was a wide as recommended. Later on I did find some 14x5.5 steelies - which would have allowed a wider tire. These wheels not readily available, but they're out there. I think this was the widest made by the factory for 14" SBP.

If you haven't done anything yet, this is a good time to consider going to a 4.5" bolt circle and 15" tires, just as many people have said. This gives you many more options with respect to wheel width, tires, disc brake conversions, and even rear axle changeouts.
