Thread: KR133 Tire Pressure

    KR133 Tire Pressure

    Howdy folks,

    Burning up some of the older rubber sitting in the garage, and just came across my KR133 rear old ASC control tire. I remember they ran a higher pressure unlike KR108 pressure but google is letting me down on the recommended pressure? Anyone happen to know a rough number off the top of their head? Hot cold warmers anything would be useful

    Cheers

    Soft or medium? Some guys were running them down at 18-19 hot, others at 25-26 hot. Either way, they are shit. The softs are a five-lap wonder tyre, and the Mediums are an endurance tyre.... no grip but last forever.

    25-26 hot but on a 600... but yes, the KR108s or even the D212s are a lot better

    I prefer a KR108 2 anyday but thought they were pretty good over 35 track temp but finicky. 19-21 hot off the warmer from memory (soft). When they work they are not far off a 2 but the window is a lot smaller .

    Thanks all ended up getting okay wear out of them. Felt a bit spinny but got through a day on them and didnt have to use a new tire for track days . Fairly sure it was a medium.

    That's what I find with them as well... they spin a lot easier than the other Dunlop rears. Especially when the track is hot.

    Guys, I was thinking running for the first time KR108 med-soft or KR108 med-hard with a KR106 front at PI on my 1299 . Ive only ever run Pirellis. Any tips for pressures , expectation etc.

    Are these rotating on the rim due to low pressures ? Mounted without lube ?

    20psi (cold track) to 24psi (hot track) hot off the warmer. You won't spin a KR108 on the rim.

    35 on a litrebike in hot temps

    At PI in the cold, as Nelso says, I'm at 30 on the fronts. 35 in the heat at the Creek. 34 most places in more average weather.

    Treat the fronts like an SC Pirelli then.

    Yes. They feel very very similar. It's only on the absolute maximum lean, mid-turn in slow corners, that I can tell the difference between the Dunlop front and the Pirelli. If it wasn't for that bit, I wouldn't know.
