Those are likely the OEM tire sizes and they used inch size before metric. I am not sure but R may mean radial. If you google 8R19.5 there are lots of hits and you likely can still find them but might have to figure out the metric equiv.

8R19.5
Diameter : 33.6"
Width : 8.0"
Wheel : 19.5"
Sidewall : 7.1"
Circum. : 105.5"
Revs/Mile : 601
