In most cases that would be true - but if you’re driving a heavy duty truck (GMC 3500 Dually) that spends most of its’ life pretending to be a passenger car and then periodically gets loaded to the hilt, you’ll appreciate the find art of “selective tire inflation!” If I ran my dually at the max tire pressure, all the time, I wouldn’t have any fillings left in my teeth and I wouldn’t average over 65,000 miles on a set of tires. I also changed to a higher load rated tire on my Airstream - but I still held to the 55 psi inflation OEM recommendation and I made sure that the trailer was loaded accordingly. In 60 years of driving I’ve never had a blowout on any vehicle I was driving or towing. I attribute that to religiously monitoring my tires - and to a lot of luck with avoiding road trash.
