Recommended Taskmaster Provider or Westlake Tires With Load Range G For Horse Trailer

Question:

I have been having problems with my horse trailer tires. It is a dual axle trailer with 4 tires. The trailer weighs 4500 # and the weight of the horses I haul is about 3300# plus some extraneous stuff. The total weight of the trailer loaded is about 8500#. Right now I have Power King Towmax tires 235/85R16 which have an E load rating of 3640# single/3305/# dual @ 80 PSI. The tires are not old, the trailer is kept under cover in a pole barn with a concrete floor and driven regularly and the tires are checked before each trip. I have had 2 blow-outs within 6 months-different tires on different sides of the vehicle. There is no uneven tread wear and I have not hit anything to my knowledge. The tires both blew out the same way on the tread, not the sidewall. I talked to a tire and wheel store and they told me that I need a higher load capacity tire if the tire is blowing out the tread. Is that correct that my current tires do not have enough load capacity?

Expert Reply:

Looking at your tires, it looks like the middle tread is a little more worn than the rest of the tire. That suggests that your tires are overheating. It can be from overinflating, axle nut being too tight, brakes needing adjustment because they are too tight, etc. I would have a shop take a look at these things to make sure your trailer is functioning properly. You seem to be funtioning in your load capacity, but stronger tires is the route I would go as well to protect yourself and the horses.

I can give you a much better tire recommendation as well. The Taskmaster Provider ST235/85R16 Radial Trailer Tire - Load Range G, # TTWPRG235R16, has a 4080 lb single and 3640 dual load capacity at 110 psi. It has a 14 ply rating and superior siping to allow heat to dissipate faster.

The Westlake ST235/85R16 Radial Trailer Tire - Load Range G, # LHWL410, are constructed with double steel belts and plies for a long life. Nylon tread-firming belt overlays help prevent tread separation. It has a the same capacity ratings of the Taskmaster Provider tires. These tires when combined with a wheel like # LHAX209 come filled with nitrogen to maintain tire pressure longer and prolong the life of the tire and wheel.

Let me know if I can help further.
