Probably the blowing tire of topicstarter is the same as the agillis 81 mud and snow for European marked.
those give a AT-pressure of 4.8 bar= 70 psi .
For the American market they then gave it another name and printed load range D on it ( I mean to read yust over the tear).
Then Loadrange D in American is always 65 psi At pressure.
This could give a to high given maximum load of LI 115/112 given
Googled the tire in Europe and it gave 116 loadindex . When LT filled in so American 110 .
Also for Dual Europe substracts 7.5% of maximum load and America often 9%. Difference is a matter of opinion about of howmuch is needed .
but all these small differences together could mean that the blowing tire (dont say that its absolutely so and if it was not simply damaged by hitting something) was courced by an adminstrative confusion when conversing from European to American market.
So do some research yourselfes , and look at your new tires to check if anything chanched and search for something like "maximum load xxxx lbs AT yyy psi)
Then let me calculate the needed pressure with my made speadsheet and formula in wich I add some reserve to the given load on tire.
What pressure did you keep your old and now new tires on?
Need from motorhome best seperate weighed wheel(pair) loads , second best axle loads but in lack of that GAWR and GVWR.
And also handy is the maximum speed you wont go over in your use for even a minute.
