No, those are the ones to avoid. The Ford and Dodge based 1960s/70s/80s Class As are the ones to look for. The GM based Class As use wheels having a 10 lug x 7.25 pattern. All 10 lugs are used on the rear axle while only 5 are used on the fronts. They put blanking plates over the centers covering the unused front lug holes.
The 19.5 is the technical replacement size for the 17 tube type. They fit the rear brake drums of the big Fords just fine, but the 8R19.5 tires will be shorter in diameter than the 20 or 22.5. Few of these old big trucks are asked to drive the highways anymore so the reduced road speed isnt normally a deal breaker. Some tire dealers might try to suggest the metric sized 225/70R19.5 which also is specd for the 6.00 wide rim, but these are shorter yet at 32 vs 34 for the 8R19.5. Stu
