    G'day
    Anybody tried running a 180 on a CBR600 rear wheel? (Stock size 160)
    Any problems?

  2. People have in the past, but now that they make 200-section rear tyres to
    fit the ZX12, they all fit those instead; they look much siccer than mere
    180s.

    It'll cost more and slow your steering down. It may not fit properly.
    Your bike doesn't have the power output that requires a tyre of that width.

    Otherwise, it should be fine ;-)

    G'day
    The whole purpose of the query is because I can get one for LESS money.

    As long as it doesn't hit the mudgaurd, swingarm or anything else, Ican live
    with it.

    Thanks

    Errr ... why ??? Not only will you have the added slower steering due to the
    width of the tyre, but you'll also end up pinching the 180 tyre down to some
    unatural triangular profile. Tyres are made specifically for certain width
    rims. The profile that they are intended for depends on the width of the rim
    etc. For sure, go for it, but your bike will handle like a brick.

    if you want it for wanker value go for it, but if you actually ride
    your bike and give 1% of a **** if it handles at all, then go with the
    160.

    I recently went the other way and downsized from 190 to 180 - my speed
    triple now handles a little sharper. I dont think I'd ever go the other way.

    BTW: manufacturers allow you to go up or down 10mm, so jumping 20mm may be a
    bit dodgy.

    All the previous replies relating to slower steering are correct. I own a
    ZX-12R and am running a 180 on the rear. It definatly tips in quicker. I'll
    never go back to a 200. One of the reasons Kawasaki put a 200 on the rear of
    the 12 was that at 300kmh they were loosng 5% of obtainable speed through
    lack of traction, bigger footprint more traction.

    Insurance Co's would loooovveee to see that on the bike when they inspect it
    for your claim. Lot cheaper for them if you put it on.

    And you'll be wasting the money you spent - it will handle like shit
    unless you make other suspension mods. OTOH if you never tip it over
    more than 15 degrees you may not notice the difference

    Or possibly a rollerskate. Quite possibly a brick-laden rollerskate,
    Maybe at different speeds. Also, it'll look silly.

    It's not really worth trying to save money on tyres.

    bigger footprint more traction.
    also more drag on the road though...

    Cant see the reason for a 200 size tire was they are losing traction
    above 3000kph.... ROTFLMAO!!!!!!!!!

    If most engineers had their way we'de be using the 180 section tyre for many
    more bikes. The litre class bikes didn't really need to go that far until
    perhaps this years models, and the GSXR1000 of 03 etc with it's steep
    increase in power. 180 is still the go even for 954's apparently if you like
    it. It does however kinda flatten out the 180 profile anyway 'cause you end
    up stretching a 180 tyre (made for 5.5 inch rim) to a 6 inch rim.

    Bike manufacturers spend alot of time and money before selecting which tyre
    would suit each bike including things such as safety, handling and best
    performance. Remember you still will only have about 2 - 3 inches of ruber
    on the road at speed? That is if your bike can cope with the change?

    If you want a Massey Fergusson why not buy it??

    Or even better if you want a bigger tyre buy a bigger bike!

    I'd much rather be spending my time riding than laid up in hospital from a
    stupid mod just so I could get the "wank factor."

    Hope that answers your question.

  16. Anybody tried running a 180 on a CBR600 rear wheel? (Stock size 160)
    With all due respect to the opinions of my fellow posters.. :) I've
    been doing a bit of silly tyre swapping lately on my bikes which may
    be relevant:

    - The 190-section rear tyre that came on my GSXR1000 is now on my R6
    (180-section wheel) with no ill effects in terms of handling
    whatsoever - folks who followed me down kangaroo valley road on Sunday
    are welcome to dispute this. :)

    - I've been running 180-profile slicks on my GSXR1000 (190-section
    wheel) track bike with no ill effects either. I did find, though,
    that when I moved to a 180-section wheel (off a GSXR600) as well as
    the tyre, the rear of the bike felt "lighter" and seemed to turn and
    spin up a little easier, but when I moved back to the 190 wheel the
    next trackday I found myself doing consistently quicker times than
    I've done before, in line with my continued gradual improvement, as
    well as feeling oddly more comfortable in tricky corners like T7 (at
    EC). So I suspect it was all in my head anyway.

    In conclusion.. going 10mm in either direction seemed to do nothing
    at all in terms of changing handling that I could notice, against the
    background of normal rider-based improvement. 20mm may be pushing it
    a bit, in that the tyre may be deformed inwards too much and possibly
    burst over the rim in extreme circumstances. If you're getting the
    tyre cheap off a mate or something and only running it on the road,
    it's got to be worth putting it on and seeing if it looks worrying.

    (If it explodes and you die, we never had this conversation and you
    were a fool to listen to the advice of an Internet random.)

    Cheers

    Thanks mate

    This is the most intelligent reply I got.


    The rest waffled on about "wanker factors" and "truck tyres"

    The queue of people with stupid ideas posted to aus.moto who heap praise on
    people who agree with their silly ideas and poopoo the people who posted good
    advice to the contrary is over there... IK will be along presently with the
