Thanks guys for all the great advice. Already called Nebraska tire. Was told the sizes I needed are in a container on one of the three hundred ships waiting to be unloaded on the west coast. Yikes. Will look again at simple and miller. As for the tractor tire guy, I am restoring this truck for a farmer on his farm. So I will talk to his tire guy. Worth a try. I just have to accept the fact that I'm going to have to put out a lot of money for tires. Thanks again.
