Tire Question???

Having work done on my camper, have a bent axle and putting 2 new ones under it.

The person working on my trailer suggest getting all new tires also and consider the size and weight of my trailer, there is a tire that has a 14 ply tread and 12 ply side wall. Don't recall the name, possibly Termainater???? but didn't realize they made a tire with that strong of side wall.

Any thoughts or ideas?

Thanks
  • I guess a ask my question wrong, it was meant to be has any one else used a tire that was 14 ply trad and 12 ply sidewall.

    The tire industry doesn't make a G load range tire with actual 14 ply tread and 12 ply sidewall...... since the '70s.
    New technology gave us a 14 ply "rated" tires that has mostly two very heavy plies that equals in strength the old 14 plys of years back.
    I used them on equipment trailers in that era. With 12 ply sidewalls/14 ply treads boy did they ever run hot when carrying loads at highway speeds.
    The new tires are just as strong (maybe stronger) and run much much cooler.

    Never heard of a Terminator trailer tire.

    Looking at the 402 QBC Salem Villa shows a 10644 lb dry with a 2431 CCC = around 13000 GVWR trailer and maybe 6k axles.

    Trailers need tires with maybe 10-15 percent capacity above the axles ratings.
  • I like to go up a notch with weight ratings of tires as it diminishes over the life of the tire. I'll be going with E rated 225 75 R15 to replace the D rated 225 75 R15 on it now when the time comes. Keep in mind tires are the first line of suspension with our travel trailers. Too hard and the ride will be harsh on our house on wheels. It can literally beat the trailer apart little by little.
  • It's doubtful that many users have even seen or heard of a tire with that many plies. That is a "G" rated tire.

    I don't know at this time on what size my old axles were and new ones going to be. Also didn't know what the tire rating is, but have always put ST235-70-16 tires on.

    My TT is a Forest River, Salem, Villa 402 QBQ.
  • You opened up a can of worms.

    What you know is the axles and tires have to be able to support of the TT. If the tires are new and in good shape it is different than if they are several years old and worn.

    New tires are almost always a good idea. That said, I just had all new running gear put on my TT because of a broken spring. I had replaced the tires and up graded from C rated to D rated tires less than a year ago, so I did not change tires.

    Not changing tire size just ply.

    Never have weighed trailer since loaded, the sticker say dry weight was 11,???.

    Still more info....

    Tires 'E' rated OR 'G' rated?

    Axles....6K, 7K ???

    Trailer....brand/model/year OR at least GVWR (Dry doesn't mean nothing)


    Kinda like "How long is a piece of rope?" ---depends!




    Actually......any time you can 'upgrade' tires is a good thing

  • More info please. Weight of trailer. Size of tires now. Axle weight rating.
    Do you have clearance for bigger tires?
