Tire age

Watch the freeways during the summer and you will see delaminated tread all over the sides of the road.
Note : the Motor homes, boat trailers, travel trailers etc... that sit all year and get taken out for summer vacation.
Low air pressure is like running low coolant in your radiator. Heat builds up to the point of tire/engine failure.

That's the boat I am in. My 'new' travel trailer is on it's 3rd summer, the tires are almost 4 years old. General rule of thumb with these tires is 5 years max. I hate to spend the money for new ones, but like usual, these look fine and have tons of tread left. I think I am planning on waiting till spring and then getting a new set. Still before the recommended time, but this brand has earned the nickname of China Bombs, since the RV companies skimp out on everything, my camper with a GVWR of 7600lbs, that came with 2 3500lb axles and tires rated for 1820lbs. If I load it to the max the tires and axles are too small, but it saved them a few dollars. I'll be going with a heavier duty tire that has a higher load range and more plies in the sidewall, you know, what the manufacturer should have used.
