What causes a random flat tire?
 
The other night I had a dinner meeting, and was the last to leave the restaurant. I loaded up my equipment into the Wrangler, started to back out of the parking space, and noticed something felt odd.

I got out, walked around the back (no problems), then saw my right front tire was as flat as a pancake. Being 9:15 p.m., in a suit, and no gas station in sight, I did what everyone would do.

I called a buddy to help me. :)

He was there withing ten minutes, with an air compressor. I aired up the tire, headed home "the long way" with gas stations all near, and even stopped mid-way to check the pressure. Everything was fine.

The next morning, I got up... tire was fine. Drove all day, all week... no problems.

So, what the heck causes this?? The valve cap was on, there was no sound of air hissing out, no signs of vandalism. I have no idea what caused it.

The temperature was mid-50s, if that matters at all.

Thanks for any insight!

It is possible that some kid came along and just let the air out of the tire. When I was but a wee lad I recall having done the same thing on an occasion or two. 'Tis but a possibility.

Spray it with soapy water and look/listen for a leak. If you find nothing, and it continues to hold air, then I would suspect as Mr Mac said that it was a random act of a prankster.

Another vote for an a-hole with no respect for other's property.

When I bought a new set of BFG MTs after I bought my jeep, some a-hole went through our neighborhood slashing tires. They got one of mine. Fortunately for me, the tires had a No questions asked replacement policy.

I've seen tires that had a small nail in them that only leaked when parked a certain way.

Could be a bad down stim. I've had that issue before

you mean valve stem? to be on the safe side have it checked out,like previously posted could be a nail or a bead leak that only leaks when its parked on that spot,better safe than sorry if you have it looked at

I've had that 2x on my back drivers tire. It was low and I filled it. It was fine for 2-3 weeks, then it was totally flat. I filled it up again, then spent 30 min trying to find a leak with soap +water, but got nothing. Its been holding air for about 2 months now. My thought is it was slipping a bead during hard cornering with the low pressure I run (25 psi). I bumped it to 35 psi the last time.

IslandTJ 11-14-2011 11:29 AM

Did you recently go wheeling? I had an instance where I brushed my wheel hard against a tree root on a trail and soon afterward, someone was signaling to me that I had something sticking out of my tire. I stopped and got down and lo and behold, there was a nice piece of root that lodged itself in between my wheel and tire bead. Before I pull out the debris, I did manage to hear air coming out of the tire. Once I removed the offending root, the air stopped leaking and I continued to wheel.

When I aired up after wheeling, everything appeared to be fine. A week later, my tire was flat, apparently there were pieces of the root still lodged in between the bead and wheel and worked its way to creating a gap where air could escape. I guess the momentum and forces created during tire spin on the road was sufficient to work the wood back out on the bead for air to escape :(.

UnlimitedLJ04 11-14-2011 11:39 AM

random flat tires are usually caused by random crap thats in the road...nails, screws, bolts, spark plugs, metal debris, wood debris, etc.

look the tire over carefully, i'll be you find the culprit. today's tires are pretty good at sealing themselves off to let you get to a shop. I drove around for months & a few thousand miles with a 3" roofing nail in a tire, held air fine :rofl:.

jiminmanjr 11-14-2011 12:12 PM

Hmmm... appreciate all the input.

My Jeep was parked on the courthouse square, downtown. I guess someone could have monkeyed with it, but in daylight, with all the shoppers walking past, I'm not sure that is the answer.

I will try the soap-and-water. I need to have breaks put on in the next week or so, so I will have my tire guys check things then.

I've been over the tire more than once since the flat, and once took a magnet over it to try and find a "pull" some place. Nothing there either.

Thanks for the input!

MikeMTJ 11-14-2011 12:34 PM

I've had issues with my rim being a tad corroded around the bead. Had it cleaned, ad it's held air ever since.

Just a thought if you live in a salty winter state.

Another Guy In A Jeep 11-14-2011 12:38 PM

Not sure, probably a kid.

czkarl 11-14-2011 12:49 PM

Like everyone else has said its probably a prankster but who knows... I once blew out a full size tractor tire with a push pin thumb tack.... :facepalm:

I have also seen this many times get a bottle of soapy water and spray it down good

hambubba 11-14-2011 06:31 PM

I had a flattie that the tire shop tried to fix twice... they never found a leak. One of the mechanics happened to look in the valve stem plastic cap, and it had a plastic nub sticking down from the middle. It let its own air out!

village idiot 11-14-2011 06:50 PM

I've had a tiny pebble lodged inside a valve stem cap that did exactly the same thing. Drove me nuts for a little while.

TJWenatchee 11-14-2011 11:22 PM

My dad once had a tire that kept going slowly flat but at varying rates. 3rd time to the tire shop they found rust where the valve stem passes through the wheel. They removed all four tires, sanded down the valve stem holes in all four wheels and put in new valve stems. Never a problem after that.

Rayko 11-15-2011 08:12 AM

I keep a can of that flat tire stuff in the back. I haven't used it yet, hope I don't have to. I did need it on my Explorer once, worked great.

happened to me too on a cross country trip, after one stop it was just completely flat, it was a bad valve stem, they were brand new tires and couldnt find a hole, i filled the tire and it felt fine, then i wiggled the valve stem and air started comming out pretty good, went to a discount tire and the replaced it for free in about 2 minutes

I would only use that as an absolute last resort. I've heard horror stories of trying to get those tires to balance right after using similar products.

Dr_Strangelove 11-16-2011 12:12 AM

Take it to a tire shop and have them look at it. I buy mine at Sams and get the lifetime warranty, it's well worth the $15.00 or whatever a tire.

jiminmanjr 11-17-2011 02:15 PM

Thanks for all the input. Man, I love this place!

jiminmanjr 11-20-2011 04:07 PM

Just got home about an hour ago. Jeep had been parked in the garage since early morning.... And same right front tire was flat. So, I know it is something non-random.

New brakes go on Tuesday. I will have them check it then
