    Hey guys, Thought this thread may be handy for reference!  :D

    What tyres and pressures are you running your across'? Obviously the original type that went on it aren't available anymore and the pressures stated in the manual are irrelevant with changing tyre technology.

    As for me i grabbed a set of pirelli sport demons to replace the gt501 dunlops (that i thought were shocking, albeit they were really old) and love them thus far, haven't had any scary moments unlike the dunlops.

    The pirelli site didn't state any pressures aside from 42psi as the max on the wall of the tyre but with some experimentation found that anything under 33psi on the front and rear makes it steer horridly slow and  weave and such, as well as returning pretty dismal economy. 40 and over on each tyre makes it horridly twitchy and the ride is pretty hard. 33 front and 38 rear, cold, for me seems to be the goods! (only weigh 60kg~)

    interested to hear what other combos people are using these days, most of the places i talked to here indicated they didn't want to carry the bridgestone BT45 tyre anymore so arrowmaxes (yuck) and sports demons were really the only option about.

    Cheers  ;D

    i learnt years ago about tire pressures, no matter what bike i ride nowdays, i set the front the 38 psi and read to 42 psi and its all good, be it cruiser, sports bike, sport tourer, if its a road bike, thats what i set them to.

    anything lower and the bike will follow the contour of the road and be frightening to go round corners with.

    You must be reading my mail, mine are set at those settings also.
    I check my pressures often specially with the Honda Blackbird as it is a heavy bike.
    Correct pressures make the ride so enjoyable.

    I'm running the Pirelli Sport demons aswell, the bike had on the rear a battleax (cant remember which model exactly) but was right on the wear indicators so it was on for only a couple of rides before it was changed.
    Front is a reasonably worn sport demon (getting replaced soon, for another one).


    I can't say I've had any problems with them, although my pressures are a bit low, 36 front and 32 rear, next time I'm at the servo they will be going to 38 front and rear, see how I like that.


    I went for it after reading other people use them and saying how great they were.


    The other ones I was considering was
    Dunlop Roadsmart (I believe they are made in the correct size).
    Continental Road Attack 2 (sizes go around the Across's needs I think).
    Metzeler Sportec M5 Interact (I think they come in the right sizes).

    I always bought Michelins for my Across's, but my local bike shop was doing them cheaply...

    I put my tyres up to 38 front and rear and it felt much better, will lean and corner easier now.

    funny about that.the bike will be easier to ride in a straight line as well cos it will no longer follow the contour of the road :Thumbs_up:

    wow. ive been running the 29 front and 33 rear as stated in the manual. im a very new rider and thought that the problems ive been having are either newbie problems or bike fault. ill try increasing the pressures like you guys have done and see the difference.
    thanks guys

    I now run 33 front and 35 rear, find it's a bit better under breaks and they warm up easier.


    Pressures are dependent on rider and tyres themselves though.

    Didn't know you'd run pressures that high.
    I stick 32 in the front and 36 in the rear on the CBR250 as per the 25 year old manual...am I doing it wrong?

    I was running 36 - 36 with some bridgestones but my front tyre at slow speeds still follows contour of road.
    Ozbikers post looks very convincing lol.
