Replacement Tire Recommendation for a 14,000 Pound 5th Wheel Trailer with 235/80-16 Tires

Question:

What tire can I use on my 2010 38 ft fifth wheel to prevent blowouts. Usually happens at around 3 years on tires with a lot of tread on them . I always keep tires inflated to maximum psi. Trailer weight is 12500 dry and 14300 max loaded. My tire size is good year ST235/80R-16. Load range E. They are mounted on aluminum rims. Thank you

You could go to a slightly larger tire, 235/85-16, and get a higher ply rating which will mean the tire will be stronger. I recommend # TTWPRG235R16 which is a Load Range G rated for 4,400 pounds at 110 psi. It has a ply rating of 14 and an M speed rating (81 miles per hour).

The issue you have had could be related to capacity. If the front of the trailer is riding high then that puts more weight and stress on the axles. Be sure to keep the trailer level in addition to keeping the tires inflated to the max psi indicated on the tire. I have included a link to a video review of the above tire for you.
