Tire blowout

I have a 2006, 28' Puma. the loaded weight is aprx. 6800lbs. I thought it was a hitch issue, a lot of bouncing. Turns out it was my second thought, tires. Had hitch adjusted and ten miles down the tollway had a blowout. This is my second set of tires, Carlisle's about 4 years old, don't tow a lot of miles each year. Trailer kept inside for winter storage, and I keep my tires covered during the summer at outdoor storage

Forgot to address this issue in my above post. Most folks know tires on a trailer operate better/last longer on average with max sidewall pressures for many reasons.
Tire makers tell us to use max sidewall pressures when the trailer is sitting in storage. Goodyear at one time advised 10 percent above max for storage.
I use four different brands of LT or P tires on all of my trailers. They all recommend max pressures when the trailer is in storage in my trailer and tractor sheds so their easy for me to maintain.
I jack one end of a axle on my 11200 lb RV a couple of times a winter and rotate each tire 30-40 degrees so it doesn't sit on one spot for 5 months at a time. My equipment trailers don't sit with a load so no issues with then for 8-10 years.
I average about 7 years and 50k-55k miles on my tires on all of my trailers. Having towed commercially with these size tires/wheels and axles on flatdeck trailers I also check the tires at each rest/fuel stop from habit.

Keep those ST pumped to the max unless you have over tired the trailer. Then its a guess and a compromise.
