    Default Cracks on the tyre sidewall

    Is the tyre still driveable when you clearly see cracks on the sidewall? Should I get it replaced asap?

    You can see the crack quite "openly" where the tyre is bulged/squash when in contact with the ground.

    ...hmmm...an interesting conundrum...
    here is an idea/test....Get her (the car) on a hwy and hit...lets say...160 or 180 kays...keep it up (the speed) for 2 or 3 minutes....if she (the car) doesnt blow her tyres...then they are fine...but if she (the car) blows them...rolls your car and possibly destroys several other cars and kills their occupants...then I d say i d change them (the tyres)....


    ...actually..now that I ve thought about it a little bit longer...thats a pretty shittty idea/test...

    So...I suggest you just change them (the tyres)...seriously...when was the last time "cracks" on anything was a good thing...

    OASN... cracked tyres are not roadworthy...

    get them changed ASAP...trust me...blowouts at high speed are not pleasant things... (citroens excepted-cracked tyres on citroens are fine)

    As much as I like destructive tests, your suggestion carries a high risk that my life (and other ppl lives) can end rather quickly and abruptly. But they do say that just before you do everything goes in slow motion.

    "cracks" on things (usually a she) can be quite aesthetically pleasing......but that discussion should really be discussed in a different forum ...hehehe

    I did wondered how the heck my car got through road worthy with those tyres .....I don't think it happened overnite.

    Only Citroens with Diravi steering can still drive with cracked tyres

    I always thought it was "divari" not "diravi" you learn something everyday.

    There was cracks in the sidewalls on the 505s front tires, I replaced them, there's other ways I'd rather die...

    Thanks

    And they don't corner well because the sidewalls have lost their integrity.

    OMG!

    I am in a Peugeot forum. (I am a dyed in the wool Citroen guy but I have been around plenty of 505's as we used to do the warranty work on the cars back in the late 1980's when they were still being sold in the states.
    And yes, I have met Shane and some other Aussies here on the web, and even met a few in person for sit down dinner.
    So some of those previous comments were funny.

    This happened when I let a friend drive my car:



    OK, not really their fault! Old tyre with cracked sidewalls, let go on a country road at 100km/h. Barely felt it, luckily the tyre was to the rear.

    Thats not bad....

    I once had blowout on an old merc...doing about 100 down dandy road...she delaminated completely (although there wasnt much to begin with-uni student back then)...Good thing was...there wasnt much to take off for the tyre guy...just shreds and bits of melted rubber...
    Taxi driver behind me pulled up and swore that if I had been in Falconski or a commonwhore i d have rolled...my girl was impressed the way i managed to control the car...but in an IRS merc its pi## easy...

    After some revealing experiences with tyres on older cars I consider it is vital that they are replaced.

    Had an older tyre disintegrate travelling on the freeway. Also had several others, on older cars, that started to de-laminate and had the effect of making the tyre an oval shape as tread lifted in one spot and on one side of the surface in contact with the road. Unless you take the tyre off the car they can be very hard to spot. Didn't notice any heat in the tyre when checking just a funny wobble when driving.

    On Saturday I put new tyres on one of my recent acquisitions. Front tyres appeared sound, good tread and may have been OK - BUT they were 2003 manufacture. The rubber compounds deteriorate with age and looks are deceiving. For $400 you can at least be safe and ensure no drama for yourself or others. If you have the cash then you could put something better on.

    If you can't replace the tyres DON'T take it on the road - PLEASE!

    I recently got rid of the Michelin XZX from my low mileage '79 504 that were in storage.
    They had perished sidewalls although the treads were still 80%.
    They were, after all the original fitment.
    The spare was near 100%, no cracks, hidden away from the sun I suppose.

    Thanks guys, thanks for all the advice! Totally understand not to skimp on tyres, they are afterall the only thing keeping you in contact with the ground once you are in the car!

    Will call some tyres ppl today and suss out some prices.

    I'm undecided on 2 tyres..... Potenza S001 or RE-11. Wanna go with Michies but PS3s seems a bit lacklustre in performance and not made in France.

    BW205,

    After checking my tyres as per your comments I find my last two sets of Michelins were made in China.

    After 50 years of buying Michelin I will now be looking at anything made in Australia or Europe.

    Suggestions for BX 1600 Slugomatics, please.

    Sadly,

    Fento

    By the looks of your avatar, they're not. They're keeping you OFF the road.

    Are there any tyre manufacturing places exists in Australia?

    I am not too sure where Continental Tyres are now made, I remember the high/super/ultra (take your pick) performance tyres were made in Europe.

    I have ordered a pair of Potenza S001 for the rear wheels. Apparently they are "newer" than RE-11 (S001 came out early this year). Will know how they are after a week I suppose.

    I wish I can drive like that (in a controlled environment )

    Does the Diravi steering still work when the tyres are off the road?

    I ended going with a pair of Potenza S001 on the rear wheels.

    No impression of them yet cos it was put on last nite and wet roads in HK the last couple of days can't really tell the difference between these and the cracked Contis. They do feel a bit firmer though.....but that just could be me paying attention hahah

    These S001 are Made in Japan in 20th week of 2010.

    Painful but correct!!! I've chucked a few Michelins away for the same reason. I find that after 20 years or so they do crack a bit..... I had a tube die after nearly 30 years, checked my stock of old s/h spares and threw all but two of them away.

    What NO-ONE has mentioned here is insurance. If your tyres are judged unsafe, and cracks would be enough, you probably are not insured for anything at all as you have breached your obligation to have your car roadworthy. This is megabucks territory if you have an accident and someone is hurt and damaged chronically. Or if you hit a Countach or something.

    Take no chances with tyres.

    Johnno,
    As the tyres in this thread appear to be of a certain brand I wonder if other brands have this problem?

    Those of us who do minimal k's in our cars may find it to be false economy to be opting for certain 'elite' brands.
    Time would run out long before the expected high k's of these tyres.
    I must add that the high k's would have been definately expected in the past but maybe not on the current issue ?

    interesting..but at the end of the day its still best to buy tyres to match car and driving style...
    I ll be getting a new set (or near new) for my 604...primary concern will be ride comfort...so will be chasing a tyre with high walls...nothing low profile. The boat isnt designed for the sort of stuff one would do in an s16 or 205gti...
    This is why i d still prefer to buy good performance tyres for the 05 and s16...I m not particularly concerned about lifespan...i just want them to do the right thing when the car is being pushed...None of my "sportier" cars would ever see their tyres age so much as to experience cracking..
    As for brands...I think its a common trait..they all do it eventually...Rubber treatments and protectants would more than likely make some difference...but I m from the school of thought that doesnt care much about tyre "presentation"...FWIW only the bottom part of dunlop lettering is legible on my s16s sidewalls... not a crack friendly environment...
