Geeze now I am thinking. I have mine set at 65 psi. And I drive 70 usually with the camper. I live in new york and went to flordia in April...aside from running over a screw in the wal mart parking lot, I had no other tire issues. For the rest of the summer , and trips planned , my trips are 100 miles or less one way. Tires still look good, but now I'm worried haha. I too always thought that 4- 5 years was ok as lo g as the tires were not showing excessive wear or dry rot.
When we're they made? Date code on the ties?
And is it safe to run LT tires on a camper? I would like to know so when it is time to replace mine I will look into it. I was of the understanding that ST tires were made different, to stand up to prolonged periods of non use and sunlight.
