When my dad first gave me the truck in 1978 I drove it down to Kelowna from Fintry over about 30 miles of gravel and spent the night at my girlfriend's parents house. The next morning I was getting ready to drive it to Vancouver ( about 300 miles) and went to the truck and found 1 flat tire. I removed the tire and went to put one of the spares that I had and found out that it had a car rear end in it.( Spare tire 6 stud. axle 5 stud ). I took it to a tire place and they put in a water tank and found out that it leaked between the two stamped halfs of the rim that had been spot welded at the factory so I had the tire shop put a tube in it.
