Flat tire crash?

Post by Bigfranksr » Sun May 07, 2017 8:29 am



Hey folks, this is my second season with my GL1800. 4 weeks ago I set out for the first ride of the season, approx 3 miles from home, at 70 mph, I experienced a quick, hard shake. My wife on back asked what that was, I'm slowing, the slower I got?, the more violent the wobble , the bike was biting and pitching, At25ish, I lost it. It threw me over the right front, my wife was pinned under the right side. We were both hospitalized, wife, 9 ribs broken, Me?, Bruised black , and damn it hurt. Last year we enjoyed 6500 miles together flawless. Wife in recovery, says she will get back on the horse, she's been riding 3 years, me ? 46 years
Tpms system is a must, thinking about run flat, if only to buy a little more time before the "rodeo. I hope this helps someone to prevent this awful experience. Questions? Feel free, 35 years ago?, rear flat on my norton, 90 mph. Rear swing out, I calmly pulled over. The diff? I was 170lbs. This round?,450 lbs of passengers. Ouch, ouch.

Yes a runflat has stiff sidewalls to help in this type situation. I just finished my 4th. Won't leave home without one. Back on a spare trike take off until I get the next rf.
What were you running on?

I'll be getting the FoBo tpms to app to my phone. $99 amazon

Bigfranksr, hope you both recover quickly and completely. Mechanical malfunctions like this are nightmarish for me. Many places are having sales on new gear, so you got that going for you. :roll:

I guess I do have a question or two.
Catastrophe tire failure... What caused it?
What was the age,tire pressure,tread,front or rear.?
Did it separate the tread or just go flat?
I am glad you both survived.

I also hope that you and your wife recover and heal quickly! I will be praying for a speedy recovery and complete recovery for both of you.

Virgilmobile has asked some very valid questions that you will hopefully address, so we can all learn. And if the tire did have a catastrophic failure, what was the cause? And is the tire manufacturer responsible? Hard to prove unless the tire is examined by a tire forensic specialist but they are out there! I don't ask this to put a lawsuit on the tire manufacturer but why did it fail. I had a Dunlop Elite II develop a bubble once when I was riding in Texas. I had it replaced and then notified Dunlop. They admitted that it was a fault in manufacture and they supplied a new tire. (front tire)

It never hurts to talk with them!

Another possibility of failure, a common operator error, is not replacing an old rubber, stock style valve stem, at tire replacement or just old age from lack of use and the tread still looks good on the tire. They get old, crack and the rotation going down the road opens the cracks and immediately deflates the tire.
Tires should be changed out after 5 years old. There is a date code on the tire when it was manufactured, at the end of the tire vin, a raised box of 4 numbers, 1st 2 are the week of the year, 2nd 2 are the year.
I'm working on a 99A that the tires are from 2005. 4705 is the code so 47th week of 05. The owner blee out his knee at work in 2013. He had only owned it a short time bbefore parking it. It only has 17,000 miles on the bike.

Yes sir, Dunlop tire, replaced last season and clocked 6500. Did not replace valve stem,
Ouch again, I'll be coming out with new tire, new stems, and tpms. Thanks guys

Not a catastropic failure, I had warnings , and for all of your benefit?, the tire went flat, I pulled over, pumped it back up and inspected it on the center stand, couldn't find an issue?, so I rode on, and crashed in the next mile. Pay attention to what your bike tells you. Good, safe riding boys.

Your bike was telling you something - the wobble got more violent as you slowed. Believe it or not, the rider's first instinct after a blowout, to slow down, is the wrong one. Actually gently accelerating will normally stabilize the bike, after which it can be SLOWLY decelerated. If the wobble becomes worse, a gentle acceleration can usually arrest it, and allow you to start a gradual deceleration once again.

This and MANY other topics are covered in depth in David Hough's excellent Proficient Motorcycling: The Ultimate Guide to Riding Well, which I highly recommend.

Thanks brother!, my dads answer for everything was ," give it more gas!", I get where you are coming from, it felt like when you are hauling ass in the sand on a dirt bike. Thinking back?, I have to realize that if I'd have lost it at 70-80, I would not have survived,

I'm not afraid of gassing it?, I dig what you are saying though man. My new mirrors arrived , happy riding, be safe.

I have had two instances of flat front tires on the freeway. years ago when I was very young and very poor, I only purchased the cheapest tires I could find. I think at the time they were Cheng shin. One day I had the front go flat on the freeway. the first thing I noticed was a strange vibration so I decided to pull over and check it out. when I was down to about 35 mph the tire collapsed, I lost control and went down. it was winter and I had several layers of clothing and the bike (Kawasaki 650) had a crash bar. no major damage to the bike and not even a scratch on me. very lucky guy I must say. Now go forward about 25 years and I was riding home on my 1100 wing in the number 1 lane when the front valve stem came off. I notice a change in handling and realized the front tire was flat! flashback time and I was in the middle of rush hour traffic so if I went down it would have meant getting run over. fortunately I had stopped using cheap tires after the first crash and only use Dunlops with stiff sidewalls. the outcome was dramatically different. I was able to move over to the right shoulder and get out of the traffic. then was able to come to a stop and the tire never came unseated from the rim. That front tire literally saved my life. I NEVER buy anything but a quality stiff walled tire. sure it costs more but there are some things that cannot be skimped on.

Well folks,
This subject is very familiar to me this year. My wife and I had a rear tire failure happen to us July 28. We were fully kitted up with leather equipment. My wife more so. She had a full face helmet, chaps gloves etc. I had a half helmet and a vest, (it was a warm day). We were doing proper highway speed when all of a sudden we heard the tire sound like it ruptured. Then the bike began to fishtail on us. I did not want to hit the brakes, so I was trying to ride it out. Instead the fishtailing got more pronounced and we were quickly getting perpendicular with the highway still clipping along at about 70km/hr (roughly 45 m/hr). All of a sudden we highsided. When we came to a stop we were still together lying on the highway. Help came pretty soon after. Long story short, My wife got the following injuries. Fractured scapula, fractured clavicle, Fractured collarbone (surgery was required to stabilize) , 3 Fractured ribs. Because I wore a vest, My arms shedded their skin on the highway, 3 Fractured ribs. We had the same trajectory coming of the bike but my wife received the worst of it. We are still recouping from that ordeal. I am very anal when it comes to maintenance on all my vehicles. I will never wear out a tire before replacing it. There was still alot of tread left on the tire. Because of the injuries, I didn't get to see the tire properly after the fact. So I can't give a lot of info. I think it was a Bridgestone, it came with bike a couple of years ago when I bought the bike. So I can't say how old it was. Long story short, We were very fortunate to survive this one. I have all winter to fix the bike up properly and for us to "get back on the horse".

We just had the rear tire go on us July 30th. We were going about 60 on a country 2 lane when I noticed the wobble were able to ride it out till about 10-15 then we got thrown to the right onto the side of the road. The bike then high sided without us and landed perpendicular to the highway, broken left mirror and some more battle scars. She dug a long groove in the pavement with the right footpeg at some point in all that as well. I ended up with bruised ribs and a little road rash, my wife had two broken ribs and a little more rash than me.

It was a Kenda Kruz tire that the dealer I bought it from put on there. I had just inspected the tire earlier that week and everything "looked good". In hind sight that morning, there were some audible clues that it was loosing air somehow and we bottomed out on a dip in the road which we shouldn't have if all was well.

So, like someone else said listen to your bike!!!!! pay attention to the clues it gives you and it's never a bad idea to stop and check things over CAREFULLY.
#1 Replaced it with a Dunlop Elite 4
#2 Bought a Tiregard TPMS

#1, glad you made it and healing/healed.
In any sudden emergency (here a flat tire) it's counter intuitive to normal thinking, MORE GAS!
But ya, it unloads some weight on the front tire.

After going Double-DarkSide a few years back (almost a decade now?) I had a flat front tire and didn't know it. :shock:
We were on a major highway and running straight 99% of the time and felt nothing out of the norm other than the front felt a little stiff, no shaking or vibrating at all. Coming to a turn-off for fuel I then noticed the front felt REALLY heavy in a turn. So while she went inside I checked it, didn't look flat, just a little low. Pencil pressure gauged it 3 times, ZERO 3 times.
Finished fueling then rode it around looking for an air pump, none, and I didn't have one on the bike (DO NOW!). After riding slow on an empty side road the bike rode fine as long as I went straight, but in turns I needed more handlebar muscle. Stopped check the tire for heat, nothing unusual. Road 45 mph for couple minutes, stopped again and tire temperature seemed near normal. I carefully continued on home.
Got home without incident and immediately checked that tire-temp and again, near normal. Tire pressure, still ZERO. Later I found a finishing nail in it, patched it up both plug and a patch on the inside. Tire finished out its life without incident.

SO... how was this possible?
The tire was a Battlax rear tire up front. Rear tires sidewalls are stiffer, they carry more weight and have both braking and engine torque to tend with. IT'S NOT MEANT TO BE A RUN-FLAT... but it held up for 80 miles.
So as far as I'm concerned, using a rear tire up front is a little safer, I'll continue to do so. I like that little extra margin of safety.

While riding my 1995 wing on the interstate at about 70 mph the tire blew. Rear end started dancing left and then right, not violently but enough to change lanes. As I slowed down it kept up the dancing. Thankfully the cars behind me had the presence of mind to slow down and keep the traffic well behind me. It allowed me to more focus on the handling. I was able to stay upright and bring the bike to a stop. I just let off on the throttle gradually. I hope to never have that happen again. This happened on my Norton back in the seventies but nothing can top a 900lbs wing blowout unless its the front wheel going flat.
