    have no sufficient information to support my hunch, but I somehow sense a burnout having something related to this image. Also on the first image you see the tyre with plenty of thread in the middle, and the second, the tyre is down past the wear markers. something funny about that.

    I've seen the same on PR2s on a ST1300 and FJ1300 on a recent ride in oz. Both bikes fronts wore quicker than the rears.

    So a total guess on my behalf, is that it is how the PRs are made????

    Oh piss - I've got a set of PR3s waiting to be fitted & now I'm having doubts. Michelin claim better braking performance over the PR2s. Maybe the compounds are softer on the 3s than the 2s?

    That tyre doesn't show signs of having been worked hard so why did it fall apart?
    Here for the ride.

    I'm onto my second set of PR3 on the 900 and they've been fantastic.

    Just a thought, RT would be qualified to comment. It could just be a suspension issue. If that's not right, the tyre always suffers.
    Do us all a favour, by bringing yourself up to speed, before pulling onto the motorway.

    I've got PR3's on my Striple but have only done about 600 km on them so it's too early to comment on wear. However, is your PR3 A or B Spec? I understand that the B spec has a heavier carcass construction for litre-plus bikes.

    So Apart from the cupping...those here that use the PR3's are happy with them right?

    I fitted a PR3 to the rear of the MTS, when I puntured the Scorpion...and I have a front PR3 being fitted now to match although the front scorpion is still fine.

    I beleive they are great in the wet and last years Grand Challenge was dry so the odds are....

    Very happy so far. I seem to remember rather a lot of rain on the GC last year round Stratford, but admittedly not so bad as some past ones

    I have a set of PR3's on my predator and honestly I can't fault them, no slips, no slides, never missed a beat for me in the 3000 kilometres since putting them on.

    Still look almost brand new as well, if my PR2's were anything to go by I am expecting to get around 15k out of them.

    Previous tyres, have always tended to wear more on the right side and I believe mentioned above seems to be the way NZ roads are cambered? but I am no expert.

    I am concerned this cupping will lead to premature demise of an otherwsie, good tyre.

    Is any one else having this issue with their PR3's or more importantly, what could be causing this ?

    I eagerly await your words of wisdom
    This particular brand / model of tyre may be more sensitive than others to the cupping you describe. In the absence of more complete information the loading on the tyre and the front suspension ( also causing that loading ) is a major cause of that cupping. Spring rates / preload and damping calibration has a major affect on tyre wear.
    This should be looked at and to not put too fine a point on it tyre manufacturers often get unfairly blamed for what turns out to be suspension deficiencies

    Just spent 4 days Nelson Marlborough in mainly wet conditions...couple of very wet.

    PR3's felt good, I felt my confidence building to where I was riding nearly steady dry style in pouring rain....I have always been a nanna in the wet after a few scarys on Tar snakes.

    I was getting the traction control to light up on occasions.

    Good write up on the PR3 in the latest Rapid Mag from Aus

    Just clocked up 3k's on my set and haven't missed a heartbeat, still awesome tread pattern on them as well, heading to Hampton Downs for 3 days of riding (superbike school and ride day) early October so will report back how they hold up for the track and total k's I have completed by that time.

    seems to be the latest PR3 thread...

    A magic carpet (aka courier) has just delivered a set of PR3 in GSA sizes for Devil and I, this morning, from the USA (they may not be available here in our sizes until next year).

    Devil will probably fit his shortly, mine will have to wait, as a, I don't have the bike back yet, and b, the bloody Conti Trail Attacks look like they may last a fair while, even though I don't like their low speed characteristics.
