Propper Tire pressure
5er needed new tires had E loads on it local firestone claimed they couldnt get E load in 15" anymore so we put on D's tire pressure on side wall states max 65 psi cold less than 300 miles later blown tire.
I return the tire and they asked what psi i was running i stated 60 they stated oh god
you cant run more than 50 in those tires quite frankly i think they have lost there mind and that the tire was faulty and if you only put in 50 psi there squatting pretty good.
so now that im off my soap box lol what would be the proper tire psi on a tire rated for 65psi cold? Thanks in advance for any input.

....but they DID replace the tire at no charge, right? You showed where the sidewall said 65? They are FOS if they say what THEY say overrides the statement on the sidewall. If that really IS the case they are out of FEDERAL compliance.

Proper tire pressure is dictated by the vehicle and conditions. If you don't have that info, you can look it up using what weight the tire is expected to carry. But if the sidewall said max 65psi cold and you were running 60psi cold, you did not overpressure your tires.
Now, you could have an alignment issue. Did the blown tire replace one that was worn unevenly or worse than the others?

On trailer tires you always run the full tire pressure and you never go from a E to a D rated tire. Tell you dealer is is full of you know what.

Firestones ???? I stopped purchasing them way back in 1969 when they wouldn't give me a tire allowance for a tire that had a bubble in the sidewall.

OTOH D range is too low if that's what originally came on the trailer, like others have said. Go back to E, run 80psi (max) on those trailer tires.
I've read good things about Maxxis, if I didn't run LTs I'd think about those.
