Still dealing with a Marathon blowout. My research on the Montqna site shows that opinions are all over the place on what to use to replace them. My 3455Sa is a larger Montana and it makes sense to consider a G rated tire rather than go back to any E rated trailer tire.

My local trusted tire guy suggested going to a standard trailer tire size 7.5 x 16 as used on commercial hot shot haulers trailers. Now in
Texas we know how loaded and how fast these trailers are on the highways. The tire he sells to all the oil field service companies here in the Barnett Shale are G rated, 14 ply and about $ 170 each. They are a little under 1 inch taller in diameter and weigh a LOT more than a Marathon.

Why not use this type of tire rather than a light truck or G 614 ?
In dealing with Goodyear , I have been advised that I cannot buy a G 614 unless I go to a Big Truck specialty store in north Fort Worth. Regular goodyear stores can't sell them. And they are expensive.

Anybody else go to the 7.5 truck tire ?
