Trailer Tires

I ordered some 6 ply trailer tires that are load range C. The tires that were sent to me say load range C but it also says 4 ply tread and 3 ply sidewall not 6 ply as they advertised.

Do they actually make a full 6 ply tire or is that 4 ply tread and 3 ply sidewall an industry standard?

    What they are doing now is selling by rating. I went thru the same confusion when I purchased tires for my trailer 4 months ago.

    The tires have a 6 ply rating, but have only 4 plies as the plies are thicker and stronger than when the rating system was put in effect.

    Best buy by the weight limits. Hope this helps.

    Here's how that works: You will notice that your tires don't say that they're 6 ply, they say 6 ply RATING. The ply rating on tires is figured on when tires had rayon, or nylon belts.

    Myself, I pay no attention to ply rating. I look at the load range, and the pounds they will carry.

    I didn't realize that nylon was weaker back when they wrote that standard. These say 4 ply nylon tread and 3 ply nylon sidewalls. When did nylon become stronger so they could use less of it?

    Just a suggestion, if you can find a service station or garage that has it available, use nitrogen in your tires instead or air. I recently bought a new RV that came with nitrogen filled tires and the ride is noticeably smoother. I did some research and supposedly nitrogen filled tires run cooler and the tread will last longer in addition to the smoother ride. Probably costs a few dollars to fill each tire, but from now on I am going to use nitrogen in all my tires.

    Best of luck.

    Something to think on.

    quote:When they remove the oxygen and trace gases from the air, they also remove the moisture. Dry air in your tires is a good thing, particularly in cold climates. Commercial air compressors knock out most of the water, but nitrogen is dry.

    All the other claims you hear about nitrogen in tires are BS.

    Costco puts nitrogen in your tires as standard practice. I think that?s nice, but if it were optional and they wanted a buck a tire to use nitrogen, I probably would not pay for it. I add air to my tires in my garage with a hand pump. Hand pumps don?t remove any of the moisture from air, but I live in a dry warm climate.

    I've seen SL(standard load) tires listed with ONE ply sidewalls.
    P series with 2 ply sidewalls. C rated with 3-4 ply sidewalls.
    I don't even bother to read the E rated tires--they are what they are so inflate to 65-80 PSI and drive.

    No run flats? Better throw in a plastic tube for Red Neck run flats.

    Toyhauler came with chinese "C" Maypops. Didn't last very long.
    Upgraded to Maxxis 8008 "E" and haven't had ANY tire issue since.

    rv.net mostly agrees.

    PS FYI Our hauler had tires from the dealer that were NOT up to the load the hauler was rated for.

    By law, load ratings at specified air pressure are listed on the tire sidewalls. Always a good idea to refer to them for your own application. There is always trial and error to fall back on.

    And don't forget when you rotate your oil also change the air in the tires about every 5k miles unless it's synthetic air.[;)]

    When you do this, do you jack up and the tire and set a cinder block on it?s side?

    And is it okay, if you don?t get all the regular air out, before you fill it with synthetic air, thus having a mixture?
