    Default De-laminated KM2's

    Howzit all,

    Just checking if any of you have had this.
    A while ago my wife mas driving along the highway and all of a sudden the car started shaking violently and there was a huge noise.
    She pulled over only to find that the tire had de-laminated and caused the attached damage.
    I got to her and replaced the tire with the spare, luckily I have 2, and put the other spare on the back.
    Not 200km later the other one on the back started doing the same thing. Luckily I was driving and pulled over in time.
    My questions are if anyone has had this problem and even though the tires are 5 years old, they shouldn't de-laminate like this.

    Cheers

    Gareth

    hot vulcanising can only deteriorate when exposed to extreme temperatures and very low pressures as far as I know

    Pic's of the tyres please. A friend has recently experienced something similar and although Michelin eventually replaced, they advised him that they will not do it again. Their argument was that tyres were under inflated (he was running at 2.4 bar) on his Hilux d/cab. They advised minimum pressure of 2.7 - tyres BFG KO2

    Howzit G

    I had 4 tyres almost do it to me, funny it was KM2ís aswell.

    These had been well looked after KM2ís, wear was even and hardly any damage from Offroad. Yet you could see it start happening in the different color of rubber.
    Iíll try look for a pic of them.
    Zach on the site had his spare de laminate on his disco, it looks let a retread tyre.

    Seems like the BFís donít like living around the 5 year mark. I have a WestLake mud on the isuzu itís 6 years old and still looks good, the Fortuner has a 5 year old Dunlop and I used it to help a mate and he ended yip doing 1600km on it no problem.

    I think itís got to do with the rubber used for those long kilometers the BF rubber are know for.

    I have switched over to all terrains now since I am using the bakkie for work and doing a lot more tar.
    I will see how they perform nut as far as I am concerned the BF's are still one of the best tires on the market.

    I've seen tyres do wonderful things after the five year mark. From de-lamination up to one that looked like it was getting acupuncture the way the steel belt protruded from the tread...

    Not good! Usually retread tyres does that. Obviously too low pressure will cause overheating and most likely the tyre disintegrates eventually when the side wall goes.

    BFG isn't what it used to be anymore.

    I had chipping on my AT tyres and the michelin reps gave me the run around as well.

    If you say 2.4 bar is under inflated when it's supposed to be 2.7, then you have to stop every 500m decent to sea level to readjust.

    What a stupid response. And if a tyre is that sensitive to pressures it should be sold as garden pots for your flowers because it's a crap tyre. What an absolutely pathetic response from the michelin guy.

    Guys. Being in the tyre game, I'd be hesitant to fit any imported tyres. I've tried to get claims from the Pirelli and Michelin crowds and they are not eager to please. Their idea is: we make a superior product so it doesn't do that.

    Local guys, Firestone, Dunlop, Continental, and Goodyear. Their backup service is excellent. I've dealt with most of them on claims before and always been a pleasure, in fact, some of the cheap chinese imports, I have found to have better back up service.

    Sorry guys I have aired my BFG views on the forum before but I think they are good tyres but you get a bum batch now and then (remember ContiCracks). Problem is local "agents" won't support claims. I also had every sort of bs when my set popped up a few tread blocks and punctured at modest pressure and use. Then one delaminated properly; a bit like your pic but water had got in at a plugged puncture, rusted the wires in the bead / carcass which then popped off, mostly making one hell of a racket but the tyre itself did not deflate so no real issue.

    Bottom line; I'd only buy at a slight premium (say 10%) to other brands and only because, particularly noticeable in sand, they have a demonstrably stiffer sidewall, which is borne out in tests. Otherwise not worth it (IMHO of course).

    I cant but think that this is an abnormal case.

    Three tyres like that. Major abuse, totally wrong application, old and abused, you name it. How many kilo's on them.

    Apart from the obvious damage, those things look wacked in a general sense.

    Thanks for the responses!
    If the tire life if worked out by time, what if, like me your vehicle stands in a garage most of the time as I only used it for trips.
    Do you have to replace the tires every 5 years, even though they arent worn? Seems like a bit of a racket to me

    Racket or not, that's what they suggest for safety reasons.

    Please post what date of manufacture was.

    Indeed....doesn't matter. If the vehicle was standing for 5 years the tires are considered to be a hazard

    Im not saying it was standing for 5 years!!
    Im saying that it is not my everyday driver, so maybe stand for a month or maybe take it out over a weekend. It never stood for long periods
