Multiple Tire Blowouts

I have 6000# GAWR vehicle certified axles. I use ST235/80R16 LRE tires inflated to 80 PSI which provides 520# in load capacity reserves per tire. I replace them every three years.

Ouch...thats gotta' hurt. This is the biggest reason I don't use ST tires on my RV trailers. Hell I couldn't afford them.
I've used LT235/85-16 E tires on several trailers with 6k axles and replace them when they reach 50k-55k miles or 7-8 years which ever comes first.

Anywayz the legalistic sounding opinions were hearing from Cal can be read over and over ad nauseam by searching FastEagle on this website (and other rv websites). Don't feed the troll.

As you well know my original trailer tires were ST235/80R16 LRD and made in the USA . The number of failures in the first couple of years forced me into trailer tire researching. Numerous trips to the scales and an increase in load range from D to E solved most of our failure problems. Because of our trailer's 32" axle spacing, center to center, taller tires than what we already use wont work. Sometimes we changed sooner than 3 years because of mileage. The newer higher speed rated tires with better compounding should go 5 years depending on mileage. We now have the option to go up to LRF but the LRE have been successful. But we would have to change wheels because ours are pressure rated at 80 PSI.

To be fair about tires I'll point out that we do not skimp. In the first 200K on our dually it had 5 sets of tires. No matter what they look like, when they start breaking out with a little extra torque I change them.
