Powerking Towmax ST235/80R16 Tire Failure

I have had 2 of these tires blow out in a distance of approximately 150 miles of each other.

The first blew and caused $2000 in damage to my 2011 Keystone Cougar 328QBS ... the second happened the day I picked up the trailer from the dealership from being repaired and caused another ~$2000 in damage ... Both tread separation/blowouts occurred with a 0111 DOT Code manufacturing date. both at a travel speed of approximately 60 mph ... both inflated to 80 PSI.

Dynamic Tire in Canada paid for the repairs on the first incident, But are acting like they are refusing to pay for the second incident.

I have found 31 reported cases on the NHTSA website regarding these Powerking Towmax tires
Has anybody else had issues with these tires
  • That size seems to be popular with blowouts. No ST is immune.
    I speculate these trailers should have 16" or 17" LT tires.
    Get LT tires that cover the entire GVWR for best results. JMHO
  • I had the same problem with PowerKing 225/75/r15/lre. 2 tire failures on 2 year old tires that did $4600 damage. I replaced tires and rims with Michelin LT225/75/r16/lre.
  • There is a long long history of Chinese ST tire failures and damage in this forum. Did you change the other tires yet? If not, what makes you think you won't be doing $thousands more damage? What did you replace the blown tires with?
