My 2 cents: #1: I don't know about GM for sure, but when my Dad bought an Econoline PU in 61 or 62, he said he had to buy spare rim separate. (Glove box door too!) #2: Fire Trucks, Dumps etc. would use the same size tire and if you were thinking when you spec'ed the chassis, the same wheel (Budd or Dayton). Hence there was no need for a spare for each truck. Plus, in a pinch you could borrow from the Road Dept. or they could borrow from the Fire Dept. The only engine we had a spare for was the 45 Dodge 2 Ton. The one flat we had in the 32 years I was on the Fire Dept was handled by a local tire shop. The Road guys did the same thing. Tires on the Fire Units were replaced every 7 years if IRC and went to the dumps. John
