Tire pressure....again
OK guys, I am thoroughly confused. Our right front tire has recently, in the past several hundred miles, started wearing on the outside. First thought was alignment, but the wear pattern is not typic...

Everyone is guessing without a true weight of what that tire is carrying. The placard is giving tire pressure for the tire they installed to meet the max axle load, nothing more. Weigh it then adjust pressures to meet that load. The unusual wear sounds like a broken belt(steel) inside the tire to me.
I just looked at the load rating on the tire, it was 4400 lb. i weighed it some time ago at a state hwy station front axle was 6800 which would be ~ 3400 and rear was 12800 which would be ~ 3200. The guys at the station said their scale could not weigh just one side as I wanted to so I could then calculate actual 4 corner weights.
It appears however we are under the tire load carrying capacity.
UPDATE. As a result of this thread, I just examined the tire again very closely. We have driven about 320 miles since I first noted the wear. Now the “sharp groove” pattern has rounded a bit with no other wear issues on the tire. One more telling thing that should narrow it down a bit, is that today I also examined the left front tire and found the same wear just starting on BOTH the inside and outside of that tire. Same width 1/2” or so but not nearly as deep. Running my fingers over it maybe the new is 1/16 or less
Sorry I did not check all of this today before posting. I wanted the manufacturers recommendation before Monday at the shop and was blown away by three completely different numbers. Monday should tell the story at the shop. Will advise..
