Thread: Tube tire help 2011 R12R

    Tube tire help 2011 R12R

    While at the rally, we had the tires and tubes changed at No-Mar on Wednesday. We used the bike sparingly around LEBANON for the rest of the week and then returned home to Alabama 315 miles from rally site. The bike ride wonderfully and the new tires were awesome. The bike has sat for one week. This morning we were going to take a ride and low and behold the front tire was flat. There is nothing punctured and the tire looks perfect. What could be the cause of the tire going flat. I would think it has to be with the tube?? Am I right in that assumption? This is the only bike we have ever had with tubes and the only time we have changed the tires since owning it.

    Yeah, the tube holds the air. If the tube was ďpinchedĒ during the tire change you would have known right away.
    Itís soapy water time. I would check the valve core first- air up the tire and put soapy water on the fill core. If nothing, a slow tube leak will frequently show at the hole in the rim where the valve comes through.
    Other than that, itís spin the tire and inspect for the cause.

    Thank you OM, will check it out...I was thinking that it might be at the stem or valve core. The tire looks perfect....and when we pulled up Sunday after the rally...it felt good ...granted I didnít check air pressure....but we did go from those nice temps in Tennessee back to the mid 90ís once home and itís been pushing 97į almost every day since..donít know if that has a part to play in the process, but I will check it out

    Brian was it a loose valve core or tube puncture?

    I have, over the years, had a couple of cases where a pinched tube stayed pinched enough to hold air for a few days and miles. Then tire squirm allowed the tube to shift a little and open the defect and allow all the air out ASAP.

    I would have bet good money it was not a pinched tube because it took so long to deflate.

    The Classic model, black with white accent tank stripe, has spoked wheels.

    Bro in law has one and keep trying to get him to have Woody's do the rim wrap conversion
    to convert to tubeless. There is a thread on ADV about another vendors process with silicone tape and dots over the nipple heads.
    Having a flat headed to Iowa last year on day one was aggravating to say the least on a modern bike.

    The Nine-T has two variations or more with non GS style radial spoked rims that also run tubes. Not a fan

    Thanks, Steve. I had assumed the spoked wheel variants came with the same sort of tubeless spoked wheels as the GS/GSA.
