Pics of Tire from blow out

[mini-muffin]

I finally got the pics on the computer. We're waiting for Dunlop to tell us what they think happened to the tire. Our dealer hadn't seen a tire go this way before.

Any further questions should be asked of Muffinman.

Holy crap!! That's an E2 as well! When did this hapen??? Musta been living under a rock...

Happened about 2 wks ago. He was on his way to work and luckily had the sidecar attached which saved his butt. They had construction in the area but he didn't think he hit anything. Guess we'll find out. Now stay out from under them rocks Bob. :rotf: That could be dangerous.

Not a big fan of side cars but in this case I'm very glad you have one. That could have been much nastier on two wheels. Glad he's okay.

Man, that is scary!!! glad he could ride that one out. Craig

mini!

IT ALMOST looks as if something was RUBBING all the way around the tire.

i KNOW that isn't the case, here, but looks/pictures can be deceiving.did jeff save the tire?

oh! i too , am glad he had the side car. i wish he would hurry up and BUILD his trike, so i could get some blueprints!

My feeling also by looking at the pic, sorta like it went low and the rim rode down into the sidewall and weakened it.......I also see a dent in one of the pics on the rim............Thanks goodness for the sidecar......or would have been a real mess.

It went from riding fine to flat in less than an intersection I was slowing down for a light.I did ride on it flat about a mile to get it off the road.That is not a dent or scratch that is rubber residue from where the tire sat on the rim getting off the trailer.Nothing was rubbing the tire and it was a real eye opener when the bike started shaking side to side like a dogs toy.I even looked for flat spots on the front tire because of the shaking.The tire had 6302 miles on it when this happened.

I am still waiting on the Dunlop response and told the dealer I want the tire if Dunlop does not take it. Maybe I will find out this weekend and bring it home.

As with metzler, They will not admit to any defect or responsibility, but might give you a new tire. That's what I got.......Ken

[Yammer Dan]

I think I would try to hang on to that tire. Be interesting to see what they try to blame on you.

Yeah Dan, I'd be willing to bet they will try the "you were riding on it way underinflated" load of hogwash, like they do so many others. You would think that once in a while they would just admit it was a defective tire and take their lumps.

[Tartan Terror]

Just looking at the pictures and not reading the account what I suspect is a leak in the tire. As the tire builds heat it weakens the side wall and expands the air remaining to almost reinflate the tire. Side wall fails and there you go. Did you see any small cuts or punctures other than those on the side wall? With the side car it would be tougher to feel a low tire as you are supported by three and dont lean. Generally if a tire is a blowout and was defective it would blow in one space not all the way around. That suggests the leak weakened it.

[saddlebum]

That type of side wall failure is typical of a tire that has either been running under inflated or carried to heavy a load the side wall flex's too much over heats and lets go.

[waterbug]

Glad to see you guys were not hurt in all of this!! Its not a pretty picture to see thats for sure.

[autopilot]

That sure looks like a manufacturing defect to me. The casing and the layered tread rubber totally separated! Good gosh...I sure am glad you had the sidecar on. The only tires I've ever seen fail like that are car & truck re-treads that heat up from under-inflation. Never seen it in a "new", first run tire. What's the date code on that puppy?

Sounds logical.

Glad to hear you're OK Geff, you mention you ran about a mile on it flat, that could have caused alot of what looks like separation. If they can't come up with a satisfactory answer as to why it let go, I'd maybe look to a different brand.

That is the worst tread separation that I've seen on a motorcycle tire. Almost looks like a semi-tire where the tread comes off of the casing.

Ive seen it happen maney times on first run tires one being my own. It had a slow leak and I didnt stay on top of it Finally it just split all the way around. In any case the main thing here is that no one got hurt.

[Black Owl]

Don't know much about tires, but I seriously doubt if the failure is the result of tread seperation.

Jeff so sorry i haven't gotten back to you abou tthe tire i know you called me on my birthday . I sent a email but didn't hear from you. I'm not sure what happened but kniowing sidecars as i do I can give an educated guess. It could have been a series of things. I'lltry to list them in order.

 

1.) The tire could have been underinflated based on the added weight of the sidecar. The car and its weight are like having a passenger on the bike all the time.

 

2.) As you excellerate the bike pulls sidways or crab walks.( you've heard me mention this before.) this puts sidways pressure on the sidwall if thhe tire is underinflated . under hard excelleration this would bend the tire to the side as its fighting against the tread holding The road.

 

3.) the tire may have had a minor defect that under those pressures may have just given out.

 

In the future its important to keep the tires inflated at a little over pressure to compensate for the weight and the stresses of the pull the car subjects the rear tire to.

If the tire is at pressure but looks flatter than usual pump it up to where it looks right . The down side is that it eats through the thread within a season . Thats just the nature of the beast. Again sorry i didn't get back to you before. the pictures are amazing I've never seen that happen before which makes me think the tire migh have been bad. Maybe it was old? Some tire warehouse keep tires pver their expiration date . Was it bought locally or from a catalog?
