Towmax PowerKing blow out pics
Yep this happened. Hard to believe the way the tread rolled off and sidewall split. Max air at 65psi was checked b4 leaving, about 20 miles into trip, going between 55-65 in 85 degree temps. Tires ...

hohenwald48,
what are your axles rated at, what is the GVWR of the trailer, and what is the actual weight on the axles according to the scales ?
As an example that ought to be pretty close to what your trailer is, if it actually weighs 8520 pounds, and has just 10% tongue weight, that leaves 7668 on the axles. Assuming for the sake of argument ( although this is NOT likely the case ) that all four trailer tires have equal weight, that is 1917 pounds per tire.
A good year cargo g26 commercial truck tire in 225/70-15, has a capacity of 2470 pounds at 65 psi. That is a 23% reserve margin, well above the 15% our tire engineer friends on the forum recommend. You likely have more than 10% tongue weight, if so the reserve amount is slightly higher than what I stated.
Also, do you really have it loaded to 8500 pounds ?
EDIT: I found online the specs for your trailer. Roughly 6000 empty. Almost 9K GVWR.
Here is my prediction what you are going to say the actual scaled numbers are:
approx 7000 actual
tongue 900
on axles 6100
average on each tire 1525 if perfectly balanced ( it's not though )....
if it's 600 pounds heavier on one side, no more than 1650 on the heaviest tire, or roughly 33% reserve with a 2450 pound GY Cargo G26, and obviously a greater reserve on the remaining three.
If you are loading it out to:
actual 9000
tongue 1100
on axles 7900
average on each tire 1975
if 600 pounds heavy on one side, then 2275 on heaviest tire. Leaving only an 8% reserve.
CAT scale tickets....show 'em if ya got 'em...
There is a whole lot of guessing going here by me until we see your actual weights.
Maybe it's just me, but personally, on a 9K trailer, I'd want 16" tires.
