    6000 miles is pretty good going. I think the rocky terrain in these parts is (partly) to blame for the wear I get, this one only managed 3500km, typical for me. You can see the rubber is cut up by the rocks, it's not nice and smooth like most pictured in this thread.

    Ran them in Russia, Gobi desert, the Baikal, then across a few time zones heading west. Mostly gravel.

    Wear really well. Think mine were made in Brazil.

    The 140/80/18 is the correct size for the KTM 640a.

    MT 21's and Metzler Karros are both the correct 140 size and go to tires.

    Big tires.
    Pricey so the Kenda 270'shave to do for every day.
    5.10X18.

    6,000 miles :rofl

    This was mine at just over 600 miles.

    I replaced it at 800 miles because at this point it offered so little traction offroad that was pointless to ride on it anymore. I used to run MT21's on my 200 and 350 for all woods riding until the center knobs were almost gone. But I found that is suicidal on the LC4E in the mountains.

    800 miles??? What are doing with your bike?

    With that live span I would need between 15 to 17 back tyres - in ONE year! Sweden is big! I would spend more money on tyres than on fuel!

    I guess I will go again for the incredible resistant Heidenau K60 again. Not the same league of grip, but at least 10 times the livespan.

    High speeds on gravel roads and ugly rocky trails. Flat tracking a powerful motorcycle on gravel is pure hell on tires. So is playing enduro rider in rocks with a 300+ pound, 50+ horsepower bike. MT21's held up well on my smaller bikes. But my 640 eats them like candy.

    i noticed especially on knobbies they wear fast when new because the center tread is mostly being used but when worn down more they start to ride on the side knobs next to the center knobs too so giving more tread to the ground for longer lasting wear. so when they get really far down its riding on more than half the tread not just the high center area. if you use your tire up like me you get more miles since i use them till they are riding on the carcas lol!

    That's right, they start to work on gravel when they flatten out.
    Otherwise the KENDA 270 is a better gravel road tire.
