Axel bending under load causing the inner tread to wear. Solution, need another axel.
In time single axel trailers will burn out bearings and tires due to undersize trailer for the stock Mac Trailer.
Why most of us have gone twin axels for safety and tow control.

Does anyone have an idea what is wrong? the two tires have similar wear on both sides of each tire
The pressure has been 50-55psi.
It looks to mee like the wheel have been bouncing on the road I never felt any heat build up at all.
This started on our way home from Florida last winter.
I thought I saw the left tire pointing out ( toe out) before launching, but now it looks OK,
I even checke the alignement with a straight-edge and tape mesure when I hauled the boat, all is good.
I can not feel anything loose either

New tires bro...

I actually found ST load D, 8 ply tires for my 14" rims rated for 2010 lbs. (Vs the usual load C 6 ply rated for 1700). When you can- add a 2nd axle.

You switch out more for UV sidewall damage than treadwear. Or anticipate blowout city. Keep at highest cold inflation for any road trips.
