Jun 03, 2023Blowouts can tear up a trailer costing you lots more than replacing a tire. The majority of the tire failures that I have seen personally have been due to overloading and under inflation. I would go with at least an 'E' Load Range tire and all the tire people that I talk to say to run the trailer tire at the max PSI (cold) for that tire. If you know the weight on the axles, do the math and if you have a load and tire pressure chart for that tire, you may be able to inflate to a lower PSI. I ran my trailer tires at max PSI for the last 50 years and never had a blowout. With regular inspection checking the condition and temperature of the tires, I did find once a trailer tire that started to bulge due to ply separation. The last 40 miles of a 1,200 mile trip on a single axle boat trailer. It would not have made it home.
