Tom,
Replace them. Dry rot will bite you if you don't.
I replaced the bias ply tires on my Airstream with new bias ply tires. On my
Argosy I have radials (they were already on the trailer when I bought it).
Both seem to work just fine, altho I had a blowout on my single axle Argosy
returning from International this year. But I suspect that the tire got
punctured, lost pressure then disintegrated. Fortunately the rim & wheel
well were OK and I had a spare...
