Goodyear G614 ,and Endurance Tires

A little interesting fact now with Goodyear RV tires . The G614, and all but the ST 255/85R/16 Endurance do not meet the weight rating requirements set by RVIA for 7K axles , the 10%. Meaning the tires have to be able to handle 7700 Lbs. The G614's at 3750 ,and the Endurance ST235/85R/16 at 3640 ,do not meet the weight rating for 7K axles.

Montana at one time offered the Goodyear G614 as a upgrade ,apparently no longer. Sailun now is the standard .

The Endurance ST 255/85R/16 at 4080 does meet the rating , but at 33.07 diameter may or may not fit , plus they are too big for the 6" wide rims that come on most fifth wheels with 7k axles. Kind of leaves Goodyear in the dark as far meeting ratings for 7K axles.

I would not be surprised to see Goodyear change weight ratings on some of these RV tires

    Thats probably all they did with Sailun changed to an ST and upped the rating . Doubtful anything else . If I remember the ST change had something to do with importing also


    That's what I was told. Sailun more-or-less just changed their former truck tire to an ST by changing the molds to say "ST" and different weights. Was to get around the much higher import tax for truck tires vs trailer tires. Otherwise, they were virtually identical.

    Change weight ratings, but will they actually change the =tire= itself?

    Lyle


    I " THINK" that would be a NO.. just re rate it


    If the tires are already marginal, then how can they get by with re-rating it and still have a 10% "reserve"? That was my point.

  • IMO thats one of the reasons we are seeing Westlakes ,Sailuns etc on the new fifth wheels . They meet the weight rating for the 7k axles . Yes ,and the cost.
