I found my chevrolet shop manual for 42-46 trucks and it states the correct tire based on standard equipment was a 600-16 tire.Optional equipment was 5.50-18?,650-16 or 15 inch. 3/4 ton reg truck lists 15 inch. 3/4 ton special and long wheelbase lists 700 or 7.50- 17.Strange that I always thought that I needed 6.50 -16's.So any 16 inch will work? In another section they also list an optional 5.50 or 6.00 18. I am really confused.
