I'm in the process of taking the tires off and replacing two back tires.

How do you take them apart more easily? (any tips) I used 3 pry bars & soapy water & some wrestling techniques. I don't have a rim tool.

What is correct tire size for front and rear tires?
The back old tires are BF Goodrich Silverton Extra Milliage 8 ply rating 7x20 34" tall with 5" tread with.
The Front are Lucus 8 ply rating 6x20 about 30" tall with 4.5-5" tread.

Where is a good source for tires. Believe it or not, the inner tubes after sitting flat for 23 years seem to be fine. They are orange and have steel valve stems.

Thanks,
Ernie

The original tire for front and rear were "30x5, 6-ply". Optional tire size for the rear wheels "32x6, 8-ply". The rims were 20" diameter and 5" wide. Modern equivalent tires are 6.00x20. Alternates are 6.50x20 or 7.00x20.

It is very dangerous to attempt to change the tires if you don't have a method to collapse the rim and reduce the diameter. It can be done but there are serious pinch points. A rim compressor, expander is the way to go if you don't have the special tool shown in the Repair Manual.
