    I just noticed this today. I purchased the tires last august (2012) and they're falling apart. I checked the tire pressure and it was at 37psi which should be fine for street riding. I guess I'll call Continental on Monday. Ugh.

    Looks a lot older than a 2 1/2 year old tire.

    Looking at the last pic, if that's the date stamp, it was made in the 26th week of 1976. :eek1

    HI,
    I think sidewall cracking may be covered by the mfg. , I also think distributor is/was around Valley Forge area. Call 800-847-3349 ,ask for motorcycle tire customer relations, remember honey > vinegar . I think they will help.
    Regards,Ed

    Have those tires been stored or operated in freezing temperatures?

    Was the bike parked near any Ozone generating machinery/electrical stuff?
    That will crack rubber pretty fast.
    Michelin car tyres do the same thing as well.
    Also Mitas crack around the knobs but don't seem to suffer any ill effects.

    No Ozone generators, It sits in the garage with my 91 DR650 Supermoto with old Metzlers, R6 with some old Diablo's that spent a year outside in the sun and snow, scooter, and my riding mower.
    None of them have shown any signs of cracking...
    My garage does get cold in the winter, but not below freezing.
    I do ride it in cold & hot/humid weather.

    I don't know. It's not covered under warranty, The cycle place I bought them won't do anything about it because "Dry Rot happens, it could be less than a year it could never happen"
    They ordered it from Parts Unlimited who only covers the tires from defects for a year, but they gave the guy at the cycle shop Continental tires phone number.
    Continental is going to send me a new tire, that's not covered under warrant, but it's going to take awhile. "Stock on the Trail Attacks are low"

    There's very limited information on proper motorcycle tire care...

    Someone who is in the industry told me how it happened...

    "That is cold cracking probably from shipping Container bottom of the stack tires shipped in colder months always seem to get that not usually noticeable. Till aired up"

    Makes sense since they were made in Germany in October and shipped to the US, probably a month or so later.

    I have a TKC70 on the rear of my 09 F800GS that this happened to, <3000 miles, only on one side. Very sad..

    Here, but lost. Am I lost if i know i'm here?
    The tire is old. This is not a problem/ defect, its simply age. Most tire manufacturers will have a 5 year warranty. That tire is from 2011.

    I have brand new, (mounted on the wheels but never installed on the car) tires for my BMW 2002. They're probably 15 years old right now. I don't expect any warranty from Michelin for them.
