Ok, I been doing some homework on this issue and found some dealers in the US that I can get them from:
1.) Universal Vintage Tire
2.) Premier Tire Terminal
3.) Only Oldies Garage
There is plenty of dealers in Africa but obviously that is trouble with shipping, quality, etc.
As for Walmart, I think I will stay away from there even if the tire is only $35 each. They had 155/80/13's But will only put the correct tire size on the car. So if you have 145's they turn you away and go back to doing whatever it is they were doing (at least my local store does this).
Prices from the above listed places are much higher getting into the $65 - $70 range per tire. Then of course shipping is a charge as well.
So I have some shopping to do. Good luck to the rest of you who need rubber.
