    hope someone can help

    ride in the centre of the road maybe? the camber of the road is what causes it

    I've seen this problem with bikes having air assisted front shocks. Different pressures in each shock causes the tyre to wear more on one side.

    Guess that would be the same with oil only shocks.

    Maybe there's different amounts of oil in each of the front shocks or different viscosity of oil in each.

    Change the oil using the same oil and same type might help.

    my sporty was the same....just the camber on the road as mentioned by Daggs.

    Bump up the tyre pressure to about 40 psi that should help fix it

    I think your doing well having a tyre which lasted for 2yrs

    Front tyre wear on one side has got nothing to do with road camber

    Swingarm is mounted to engine-transmission.which is rubber mounted

    On top of the engine is an adjustable link, moves top of engine left or right

    Stand bike upright with front wheel straight ahead.

    I use a magnetic vertical spirit level. Stick spirit level on front disc. Move bike left or right to set to vertical. hold in place.

    Put spirit level on rear disc and check for verticle .You will find bubble will be different

    Adjust to verticle by turning link on top of engine

    When set correctly, No abnormal tyre wear and handles HEAPS better

    Not one harley that i have set the geometry on has been set correctly in the factory.

    PS Make sure fork legs are same hight too.....First

    too true, have yet to come across a rubber mounted bike that is set correctly. there are some variables in regards to road camber, depending on which state you ride. NT has bigger cambers than most other states, Nth Qld has higher cambers as well. but the most common cause of uneven tyre wear is incorrect tyre pressures.

    That's interesting and a good set up procedure to check out but most bikes I see (mainly non harleys) have more tyre wear on the right side thats why always gathered it was due to road camber

    Jeez Dyna, if you must Drift, try and even it out to both left and right turns !

    Interesting stewy. seems an easy enough check/fix. if it is out of balance and a good place to start. I have checked my fork lengths and both are even, a mate with an FXR had the same issue and it was his forks, I have also changed the fork oil over the weekend, just eliminating... Thanks for the info guys, i will keep you informed on the leveling checks.

    I know I'm ressurecting an old thread here but is the 2008 softail set up the same engine allignment....? I have some crazy uneven front tyre wear and would like to sought it before I fit the new tyre.

    Check your rear wheel is set properly. Measure the distance between swingarm pivot and axle centres. Should be the same each side.

    Tyre pressure would be my first check

    Yep, all of the above re a softy.

     

    9 times outta 10 it's rear wheel alignment on a softy, try and get a lazer aligner to set the alignment. Bunnings, $ 25.00.

     

    place aligner on rear pully and adjust so that drive belt is straight from rear to front pully, that way wheel alignment and belt alignment are good to go,

     

    no more uneven front tyre wear.

    Hi all...My softails and every road bike[jap] I owned worn the front tire on the right side.We turn right more than we turn left due to roundabouts.

    My brother in law is a cab owner/driver and told me this.They renew tires more than once a year so they see it on cars as well.

    I thought is was due to road camber.
    Every bike I have owned has done it
