Recommended 235/85-16 Sized Trailer Tires

Question:

Currently I pull a 35 foot goose neck horse trailer with living quarters. When fully loaded it will weight 14,000 pounds. This trailer is used for multiple trips long distances from home travelling at highway speeds. Over the years I continue to see trailer tires exploding not only leaving people with a flat tire but also tearing up their trailers. I am now to the point of replacing the tires on this trailer and have considered buying truck tires instead of trailer tires because of the trailer tire problem I have encountered. The tires are 235 85 16 on aluminum wheels. What are the cons against using a truck tire on my horse trailer? What is the best trailer tire for this application and why? Thank you for your assistance.

Trailer tires have a stronger side wall than truck tires which is why they're recommended. The most common reason for tires failing is excessive heat buildup. A lot of times trailer tires are not inflated properly or are driven over their speed rating limit causing the tires to heat up and eventually fail. You should always know and stay within the speed rating of your tires. Also, trailer tires should always be inflated to their maximum psi while they're cold. If a trailer tire is under inflated it will reduce its weight capacity and therefore put more stress on the tire which will cause the sidewall of the tire to heat up.

For your trailer's 235/85-16 sized tires I suggest the Westlake # LHWL410. These have a load rating G for 4,400 pounds at 110 psi. The speed rating is 75 mph which is higher than a lot of trailer tires. The best part about Westlake tires is they offer a 5-year warranty and also 2 years of roadside assistance. If your trailer has a flat , call the help line and a technician will come change the flat for you. You can call 24 hours a day, 7 days a week, and 365 days a year from anywhere in the United States, Canada, or Puerto Rico.

A second, more economical, option is the Taskmaster Provider # TTWPRG235R16. The same load range G and 4,080 pound capacity at 110 psi. Also the same 75 mph speed rating. The main difference is the warranty is a 2-year and there's no roadside assistance.

Both tires I suggested are radial tires. Radials are better for highway speeds because they run cooler than bias tires.
