Maxxis M8008 self-destruct
Hi all, I wanted to post an experience I had with Maxxis M8008 trailer tires. This is my first post here, so I hope this is the right forum for trailer tire issues, and I hope this is not too long...
Forum Discussion
DEXSTAR has responded to me previously that there is no reason not to install a Load Range E tire and inflate it to the 80 psi required as long as the wheel LOAD rating is not exceeded .
Your not going to get any wheel maker to give a OK to use 80 psi in one of their 50 or 65 psi rated wheel when carrying a load.
The information I posted above about wheel pressure ratings/load rating matching the tire pressure/load ratings is from Dexter axle who made all Dexter wheels till the mid '00 when Dexter wheels became Dexstar wheel company.
I've seen and I've ruined more than a couple of steel/alloy wheels on my equipment trailers from over pressuring while carrying a load. The steel wheels bead seat flange split with loss of air pressure resulting in a ruined tire.
Both aluminum trailer wheels cracked in the valleys. One even cracked so bad it broke around the centers out which is typical of aluminum wheels.
Your not going to get any wheel maker to give a OK to use 80 psi in a 50 or 65 psi rated wheel and carry a load. The only place I've seen this type of dangerous advise is on this website.

Bottom Line
You should never set the cold inflation at a level that is higher than the Max for either the tire OR THE WHEEL. Both the tire and wheel manufacturers take pressure increase due to operation heat into consideration so don’t bleed off hot air out.
