I'm done with Goodyear Marathons! I just had my 3rd ST235/80R15 Load Range E blowout. Good tread, no visible sidewall cracking. two insurance claims 1st for $4k+ and second for $2k+. I'm looking to upgrade to Load Range G (14 ply). My rims are 110 PSI and the pressure for Load Range G is 110 PSI. Will I be challenging my rims with LR G @ 110 PSI or should I buy Load Range F @ 95 PSI? I considering RubberMaster Country Wide RM86 AllSteel ST235/80R16 Trailer with Ultimate Advantage Lifetime Warranty. Yes I know they are made in China.
I'm pulling a Prime Time Manufacturing 2014 Sanibel 3501 (tandem7,500 axils) 12,750 empty with a 2011 Ford F350 SRW 6.7 diesel.
