    Installing new 100/90-19
    Avon Roadriders on my Mk3 and have purchased Michelin 4mm thick Ultra Heavy Duty Moto cross inner tubes.

    Anyone done anything similar?

    Also, do inner tubes have an age expiry date?

    Cheers.

    I believe thick MX/Enduro tubes are not generally recommended for road use as they can overheat when run at high speed or when heavily loaded.

    The normal Michelin inner tubes are good and not thin. The MX ones sound like overkill.

    On a road bike no, at tarmac pressures and smooth surfaces the chances of a pinch flat are very low and that is one of the main reasons to use them.
    If you use them don't spare the talcum powder and make sure to check the inner side of the tyre/tire for any form of decal etc.
    About all they will do on a Commando is make a already heavy wheel heavier.

    I prefer natural rubber inner tubes. I believe they will not deflate as fast as buytal rubber tubes in the event of a puncture. I feel the advice that the 4mm tubes are overkill and will overheat when used on road bikes. Not aware of a expiry date.

    I wouldn’t put those in a road bike, for reasons stated, overheating! I would check with Michelin just to be sure. Off road bikes run 15psi and down. (I used to run 4 in desert sand). They are thick because of potential for pinch punctures.

    The brand new wheels and tyres built for me by Central Wheels went flat within a week and need the tubes replacing. So it definitely pays to buy good tubes.

    I went with bead balanced inner tubes on my Roadster. Only had the bike running well for a few days now and only run it up to 50-60 mph a few times, but no out of balance vibration detected. Might use these again on my modern Bonneville at next rubber change.

    As far as expiration, I don't know. But I have both OEM innertubes (Dunlop) from my 75, hanging on the wall inflated. I took them out when they were over 35 years old. Still good but I'm not putting them on the road. I find that I can get good heavy road tubes at the Harley shop, for their 19" front wheels.

    I think so!

    They changed them though FOC, they had to have the wheels back anyway to correct the alignment :rolleyes:

    Several of us in the local club tried Michelin MX tires on someone's advice.
    It seemed like a good idea at the time.
    We all had trouble keeping air in them, never figured out why. They would leak down to 15 psi from 32 in a couple of weeks.
    They are also nasty to fit and deal with if you have a flat while out on the road.
    I've gone back to standard Mc tubes made by Michelin. They are heavier than some cheap tubes but lighter than the MX tubes.

    Got that beat...I had two rear flats on the Bonne with two hours. Second was after tube replaced by a nearby Honda MC dealer...he did say he only had a one size up tube but assured me it would be fine.
    Ride bike to ferry, boards and 90 min later as I prepared to ride off, rear was flat.

    Stay away from Bikemaster tubes which don't seem to hold air over the winter. Usually much less. These are sold in multi-brand dealers and online. I've used the Michelin tubes... the normal ones, and they do hold air. So I got that going for me.
