    i have a 48'' exmark lazer z. one of the smaller front tires goes flat or off the rim if too much pressure is put on it, or if it hits the slightest bump while turning. i know these tires are tubeless, but why does it happen so often and only to one tire. there is nothing visibly wrong with it.

    tire pressure can play a big part in the tire coming of the rim. the pressure gets low and you make a turn the tire comes of the rim.

    check it often and set to what the mfg recommends.

    a slow leak cab be a pain. If all else fails try tubing it.

    Check your air pressure while the tire is cold (at night). Check it again in the morning while still cold if the pressure is low you have a leak. I have had great results with Slime, the green stuff.

    Also make sure your rim is not bent at all.

    Pull it off the mower, put the wheel in a vice, break the bead, clean the rim edge and the tire bead edge, lube it up with dishsoap rather well, re-inflte to a high enough pressure that both beads set, (you'll hear them pop), then deflate to recommended pressure. ;)

    I run front tubes in my 60" Dixon and ran tubes in my Promaster 100. Just less hassle to me, Had tons of problems with this on the promaster. My wife always struggled getting them to seat back up in the field as well, nothing like losing a day with a mower over something like that.

    Have never had one come off of my Lazer Z and they are still tubeless.

    Don't forget to slime them . That will save a lot of time.

    try cleaning the seal, there may be a small bur on the rim.
    if that doesnt work try slime have had good results with it
    if you still have a problem replace the rim and tire
    good luck

    If the bead is leaking, clean it real good (of coarse), then use a bead sealer. Most auto stores stock it. It's all most like a liquid rubber.

    J Thomas has a zero-flat tire, but they run about $80.
