Well I just had my first blowout, 40' Monaco diesel. This was a 275-70-22.5 Hancook that I put on in February 2012. I really thought they would last a little longer than this so I wonder if I should ...
I put Hankook AH-12's in 275-70-22.5 on my previous DP and they were a very good tire. I had them inflated based on the load inflation table and never had to inflate them to max. Max on those tires is 120 psi.
