Bias vs Radial Tires

I have a question regarding bias ply tires vs radial ply tires. Our T/T came from the factory with bias ply tires (Taskmaster brand) imported tire. After a few trips out and bringing the unit back to Texas I noticed inter and outer wear on all four tires almost like tires being underinflated. The tires were at the proper inflation of 50psi, tire size is 205/75D/14 load range C rated at 1760# at 50 psi. The trailer loaded checked on CAT scales is 6,665 #. The tire manufacturer has replaced all four tires, now they are begining to do the same thing again. I will be replacing all four and considering going to a radial this time. The radials are ST225/75R/14 Load range C at 2180# at 50 #psi. Note the date codes on the replacement tires were 2009, no axles appear to be bent and rough measurements look like there square. Any advise would be appreciated. Thanks

Hi, Mike and Amber. Hope you are both doing well.

I've run bias tires on both of the TT's I had. I replaced the last set with bias ply tires due to wear and one tire was "dished or cupped" out. The replacements are Carlilise (Sport Tracks) ST225/75D15. These are load rage D rated, and I've had them on for about six months with no unusual wear. In fact the tread looks like brand new. The TT weighs 7200# loaded and I keep the tires inflated to 50 psi. If these don't hold up, I will probably go with radials next time.

I would rather run the bias ply on a trailer since it does not come apart like a radial and do so much damage. On a radial, the belt will sling around and take every thing in its path out. The bias ply tires will tend to throw chunks and not do as much damage.

As for the wear, are they wearing equally on the inner and outer edges? Can you run a bit more pressure to see if the problem is fixed? Another thing to consider is the wheel bearings. Have you checked to see if they are loose?

Let me know if you need some help checking the wheel bearing play. This is my Friday off.
