The tire that had the sidewall failure had less than 300 miles on it. It was less than 2 months old. If I have to check the tire pressure each time I want to drive the f-150 then these are worse than terrible tires.
I normally drive a smaller SUV that has had a variety of brands of tires over the 10 years that I have been driving it. (185,000 miles) I take excellent care of my vehicle including the tires (rotation and replacement). I do not and have not checked the tire pressure in any set of tires each time I want to drive the SUV (or even on a monthly or bi-monthly basis). I get in and drive anticipating that everything is fine and 98% of the time over those years I have had no problems. I will get a low tire occasionally but rarely. Never have I had a tire "failure" as with this tire.
If Hankook tires need to be constantly checked for lost air pressure then the brand is bad. Based on your comment, I assume that you are advising people to constantly check the tire pressure if they are going to own these tires. Based on the Hankook website, they appear to be advising consumers to constantly check tire pressure because if the tire pressure isn't "perfect" the tire "could" fail. (Translated: likely to fail). The Hankook website stresses the danger of "under pressure" leading to sidewall failure.
My adivice is to not buy the tires. Buy tires that are not going to be a constant worry because of the safety hazard of "complete failure". Which in my experience is virtually any other well known brand of tire.
(It is interesting that there hasn't been a post on this thread for awhile and as soon as I posted a negative, someone immediately posted a positive...)
I'm sure ALL tire manufacturers advise their users to frequently check tire pressures.
It's one of those "if you do something stupid, you're going to kill yourself", which is not that far off if someone is in a 4000+lbs metal box traveling at 50+mph or so in a less than perfect condition.
Hell, the US government even mandated a law so that all 2008+ cars come equipped with tire pressure monitoring system to take the burden off of less than proactive citizens.
One should be checking tire pressures anyway, it's the only thing keeping the car and ground in contact.
Some tires are notoriously sensitive to tire pressure, more so on our soft Yoko's. I mean, isn't there a thread every now and then complaining about tire lasting some 3000miles with fat bald strips in the middle?
Fail tire not, it's usually usually user error.
I check my tire pressure every time I fill gas. What's the point of goofing around while waiting for that 'click'? I do it on set of Kumhos, Bridgestones, Yokohamas, Pirellis, etc etc etc and sometimes even on a rental car. I find that average tire mounting shops and quick service shops usually ignore the manufacturer's suggested tire pressure. It feels like they either put the same pressure front/rear or they pump it until it 'looks' inflated.
I stopped going there, obviously.
Come to think of it, when my Exige was at a shop once to get some work done(including a cracked wheel replacement), I had found that the A048s were filled to 40PSI!! Something bad could've happened(me getting killed) if I hadn't checked the pressure as I was about to take the car home.
