    Privius set of tyres on my crosstourer was Michelin PR5 and i was very happy with them so after 10000km i decide to put PR6 and now bike is pulling or falling left if i take hands from steering! I complain to the shop and today thay did put a same new tyres with no chanage!
    Before the bike was going strait if i did a same? Had no issue with this?
    What could this be, profil of tyres or something else!!  Sugestions are welcome!!

    It seems difficult to blame the tyres because once they're rotating at speed, it takes a significant amount of input to cause a motorcycle to lean. Even when tyres are badly worn, you don't normally get what you describe. Have you checked your head bearings? and it sounds obvious but are you testing on a cambered road? Are you keeping the speed constant as you take pressure off the bars?

    I had exactly the same issue when a pair of PR 6 tyres were fitted to my CT a month or so ago just before a European tour.   My bike pulled to left and cornering didn't feel quiet right with the new tyres.

    I thought it was new tyres, camber, weight of luggage etc but handling didn't improve after a 2,000 mile tour.  Rear wheel can't be out of alignment with front so issue must be at the front.

    After some investigation back home the right folk was a millimetre or so out of alignment at the axle.  On the top yoke the alignment was fine but off slightly at the axle.  After a slight adjustment the bike rides much better.

    Its worth checking.

    If you're experiencing the same thing after a second set of new tyres have been fitted, I would imagine the problem is somewhere else. It could be that the new profiles are exaggerating the problem, but not the cause.
    The cause of handling problems are often difficult to find, especially if suspension component have been removed and or you don't know the full history of the machine.

    History is not a problem becouse the bike is with me from 0km! Maybe this tyres just as you said bringing a problem up!! I going to try look in to suspensions, steering to see what is not right!

    Dangerous,  in my humble opinion there is an issue with the tyre bead / or wheel rim(s). Something is out of whack, the wheels need to be checked for true.. Spoked rims can be tricky when stresse to remove / fit tyres. Most places dont even check spokes / true.
