I have had 3 sets of Hankooks on two different cars. The GTO had RS-02's (purchased at TireRack closeout) when I first upgraded to 18" wheels and Ventus R-12's. My wife's MS6 got Ventus R-12's when we wore out the original Bridgestones 02's. No problems at all but my club racing experience has taught me to check tire pressures frequently since ambient temps have such an effect on pressures.

Check air pressure constantly?

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.

It is an interesting point that all tire manufacturers would equally stress the importance of tire pressure and especially under-inflation. So, I checked.

Hankook dedicates an entire "page" to the importance of tire inflation; Goodyear dedicates a short paragraph; Bridgestone either doesn't mention it or made it too difficult for me to find which is the same result as no mention(Bridgestone does provide extensive information to their belief that they have excellent warranty coverage); Michelin dedicates one sentence to under-inflation.

Both Michelin and Goodyear recommend checking pressure once a month. Hankook recommends checking "at least once a week". "At least"!! That appears to be an admission that their tires are poorly made and can not maintain tire pressure.

Additionally, Hankook has been forced to recall one tire for failure and blowout problems. I suspect that - as a brand - they have more tire failures than any of the major brands.

As an aside, another reason to not buy this brand is my discovery that Hankook's warranty is limited to providing a new tire but specifically does not include mounting, balancing, etc. All other brands previously mentioned claim to cover all costs associated with replacing a defective tire.

For anyone considering new tires, I urge against this brand (despite the assertion by some that the tire failure must somehow be my "fault"). The lack of warranty support - and the hostile attitude I have encountered thus far from Hankook customer service - should be sufficient to recommend a different, better-known/proven brand.

The wheel was ruined and the tire pressure sensor was also ruined.

Unfortunately, we replaced all 4 tires at the same time. I now have 3 remaining Hankook tires and am going to replace the blown one with the same tire for all the normal reasons. The problem is that I will never feel safe driving the f-150 with those tires.

I have had preliminary communications with the customer support and anticipate that they too are going to try to pass this off as some sort of low tire pressure - as a previous poster suggested -and, therefore, not their responsibility.

I will be notifying the traffic safety board, our consumer protection division, etc if for no other reason than to try to educate people about the danger of these tires. It never occurred to me that Ford would put bad tires on their vehicles. And, we didn't have any problems with the original tires. But, apparently we were just lucky as weak sidewalls appears to be standard for this brand.
I've gone through several sets of Hankook mud tires on my F150 with no incidents and I rarely check the tire pressures on my truck. Maybe I'll check them when I change the oil.

That's great - and apparently very lucky. I had the same experience with the OEM Hankook tires but they would have been built to Ford specs. (Also, be aware that Hankook also recommends on their website that the valve stems be checked regularly. Apparently that is a "known problem" with their tires which I assume is what leads to the pressure loss and with weak sidewalls to the subsequent sudden failures.)

I don't know what I'm going to do with this set. I hate to sell them "used" to somebody without divulging the known problems. But, I can't leave them on the truck and ever feel safe driving with them. So I'll be limited to slow speeds, close to home if I don't take them off.

Maybe not much an issue with their R-comps. I have used Z211 (discontinued) and Z214. Both were great. I am also running Z212 for streets. No issues thus far.

Your first mistake was driving with RS2's. These are not designed for the weight of your truck.

Did you check the tire pressure after the installer put the tires on your truck?

How long did you drive with the tire pressure sensor warning light on?

How are valve stems failing a know issue with the tire?

+1

Valve stems are not provided by the tire manufacturer, nor are they installed in the tire itself.

Tire Failure BS

I am surprised at the amount of BS on this thread.

1. The way the tire looks is horrible. The whole sidewall came off! OMG!!! It does not matter what the tire is, once you get a flat and drive on it for a while (as in slowing down from highway speed), the rim will cut the tire like a knife. So what you saw was the final result of the rim cutting a flat. Happens with every tire I ever had. Get a flat drive on it more the 30 feet, cut tire.

2. Valve stems have nothing to do with tires. They sit in the middle of the rim. Cheap rubber valve stems used in most tire shops are questionable. Good screw in type are too complicated for an everage tire shop grunt to install properly.

3. Maintaining proper tire pressure is paramaount to tire safety. If the pressure is too low or too high, tire temperature will rise beyond tire spec and destry the tire.

The real question is why did the tier fail? Was there a puncture? Valve failure? Belt failure? Low tire pressure?

For the tire to deflate so fast, there would be a puncture or catastrophic valve failure.

i used to have Pirelli winter tires (very $$$). I would hit a pothole. The tire would puncture and deflate. By the time I would have a chance to slow down, the tire would be cut. Have to buy a new tire. Happened to me twice. Great winter low profile tire. This is bad tire construction, since it would not withstand physical impact on Canadian roads.

I had written a salient and respectful response and it was lost... I am taking that as a sign that none of you really wanted to read it anyway(!)

So just a couple of facts - which are possibly "b.s." to some or most readers as the previous poster charged. However, I am unable to know the value to each of the possible readers so will post these few facts. My life experience is that most of us rarely know as much about anything as we originally think. So, I have learned caution before declaring certainty - especially when the certainty regards the experience, knowledge, wisdom and research of others.

1. I have been driving for about 40 years. I have had several flat tires. Some have occurred on highways. I have never had a "flat" that acted like; sounded like or looked like this one.
2. I have been a passenger in a few vehicles that have had flat tires. None acted like; sounded like or looked like this one.
3. Hankook is recalling 18,000 tires for sidewall failure. Despite the assertions by some posters; Hankook and the National Highway Safety Administration seem to think that tires can fail all by themselves; operator error is not a requirement. ("The sidewall of the tires can wear prematurely and/or experience a blow-out..."). I'm certain they would be interested in the opinions of those who believe that is simply "b.s." however.
4. I have no idea why Hankook thinks tire pressure needs to be checked weekly at a minimum or why regular checking of valve integrity is necessary. I'm willing to assume their engineers know something about Hankook tire construction that the lay person does not know. Or, at least, know - or believe - that valves installed with Hankook tires fail more often than other brands. Sometimes, relational outcomes are not easily explained or understood.
5. My experience and the experience of the original poster appears to have no or little value to the readers of this thread. Therefore, I will limit my comments to those conversations occurring elsewhere who choose to believe the "b.s." that Hankook tires have a sidewall problem and, therefore, end this thread as to my experience.

I appreciate the indulgence and interest of many of you.

Except that I failed to respond to the specific question of whether I checked the tire pressure as soon as the new tires were installed. No, I didn't and never have in 40 years. As I am not a tire installation expert, I have never checked the "installation" of new tires.

I also gave an incorrect impression that I had the exact same tire as the original poster. I had the same experience with a Hankook tire as the original poster but not with the same type of tire. The replacement tires on my vehicle - of which one has failed - were identical in type to the OEM tires.
The low pressure sensor did not come on until the tire failed and immediately ruined the sensor.

Sorry for the inadequate detail.

^This has nothing to do with Hankook, but you should ALWAYS check the pressures of newly installed tires. I cannot tell you how many times I pick up my vehicle with over inflated tires especially the car unless they ask me what pressure to set them to. Hell, once I was waiting for my tires and overheard one of the employees telling a customer to keep the pressure to the max tire pressure printed on the tire. o_O

Wow, thread resurrected after four years - imagine that? Same as Sam..., I have not experienced such a tire blow-out up to that point, or since then with any other tire brands. Maybe it was just a fluke or bad batch? I don't really know. As I recalled, all four tires were bought brand new and were in still great shape. Just glad, I didn't hit the center divider!
