Verified that is is a 15x5 JJ wheel which is bad. Now have Dexter Wheel, Martin Wheel, and Northern tool involved.
The Martin Site shows a
DM205R5D-5CI as having a 6" rim so it appears definite I have the wrong wheels which have a load rating 300 lbs lower than the tires.
In any event I cancelled my state park reservation for this weekend since am not going anywhere until this is resolved.
ps Dexter said "15x5 (017-143) Dexstar Wheels are rated @ 1820 lbs. @ 80PSI" so that is not an issue.
Since the size information is on the rim I would suggest that anyone with LRD tires check their rims.
