  • Strange Trailer Tire Wear

    Can anyone explain this tire wear to me?

    Inboard quarter of the tire is wearing much more than outboard.
    Passenger's side tires both look like this, but driver's side looks even.

    Weight distribution? More UV abuse? Road edge rumble marks? Bearing play? Trailer Brakes?

      My trailer is relatively high compared to Alan's same model trailer.

      Maybe the arm on the axle should pivot and it doesn't?

        How close to max GVW are you when loaded? I had a trailer that wore tires like this and it was due to negative camber as a result of too much weight. I am guilty of saying my car only weighs X,XXX but then I throw in tools, gas etc that double that number.

        We all got stopped by the commercial CHP one time on the way to the sand dunes and when put on the scales we were all at least 50% over rated capacity of our trailers.

          Commercial CHP carries scales? That is aweome.

          Next time I am worried about my race car weight or corner balance on the way to the track I am going to stop one of those guys and say, "Hey, my car may not look like it, but I suspect it weighs 25,000 lbs. Can you help me verify that?"
          To the right of The Sheriff. Isn't everyone?

            GVW is a little uncertain due to the lack of trailer information. It does have two 3500lb axles so I assume 7000lb capacity.

            My current estimates are car (2100) + spares parts and tires (500) + trailer (3500) = 6100 lb
            I could easily have another 500 lbs of stuff in the trailer but it's hard to imagine I'm off by 1000. Maybe I'll stop by a scale on my next trip to the track if I can figure out how to do that.

            It's strange the tire wear is only on one side of the trailer and the side that most definitely has slightly less weight on it.

              What is the age of the tires? What cold PSI are you running? What suspension does the trailer have? How much weight are you loading up?

                Is this the front tire?

                I'm going to guess repeated tight turns.

                  4 years old, ~75psi cold, no suspension, I'm guessing about 1600 lbs / tire.

                  Both passenger side tires look like this, front and rear. Driver side tires still look good.

                    Had a similar problem. It was a wheel bearing deflecting badly under load. If you havent done bearings on them, i know the OEM bearings from carson are garbage, you're well served to replace early.

                      This makes some sense. I repacked half last weekend but maybe I'll replace bearings while repacking the 2nd half and redo the 1st half.

                        Check bearings and replace seals every time you replace tires(5 yrs). Also, 75PSI cold seems a bit high.

                          also radial or bias ply tires?

                          My wear improved noticeably when i went to radials. The OEM bias play are pretty seriously crowned and it can cause the bearing to load up with more camber than a radial does.

                          I dont know why they even make bias ply tires for anything anymore.

                            tire states max load at 80psi so I set to 75 assuming they will be close to 80 when warm.

                            I have 10 ply radials 225/75R15

                            I think I'll replace and repack all the bearings and then probably get new tires next month.

                              I think the OEM Carson brand is Tread Star. I had a blowout a while back on my carson open trailer, and when i tried to replace my spare I couldn't even find any place that would sell that brand. The only place I have seen Tread Star for sale is at Casa Della Tires, the Cars movie themed pretend tire shop.
