UST Tyre And Wheel

    Hello.

    Cutting a long story short I have ended up with a Mavic Cosmic Elite UST rear wheel complete with a Yksion Pro UST tyre. The Mavic tyre lasted two outings before it was U/S due to a piece of flint and the only tyre I could get quickly was a Hutchinson Sector 28 at 28mm wide. My front wheel is a non UST Mavic Cosmic Elite with a 25mm tyre and inner tube. This leads me onto the following questions/queries.

    1) Can I fit any UST tyre to my Mavic UST rear wheel or do I always have to use Mavic tyres?

    2) Is it advisable to change the front wheel to UST to ensure predictable handling front to back?

    Thank you.

    Roger.

    Does anyone know if I can run these wheels with regular tyres (e.g. Continental GP 4 Season) and tubes?

     

    If they’re Mavic Yksion Elites they should be regular clinchers, the Mavic WTS wheelsets fitted with tubeless would be using the Mavic Yksion Pro UST IIRC.

    I’m using Mavic USTs with Hutchinson Sector 32s – done over 4000 miles so far and still seems to be a fair bit of tread left. Had a few punctures in that time (all off-road, gravel or hitting big stones on road), most have sealed, a couple needed ‘worms’ which are cheap and easy to carry around.

    The 30mm Mavic tyres that came with the wheels got cut up very easily and only last 1200 miles on the rear before going through to the casing.

    Quote from linked article:

    “Keen-eyed readers will note that Mavic’s stated rim diameters are fully compliant with existing European Tyre and Rim Technical Organisation (ETRTO) standards, unlike some tubeless-compatible rim and wheel manufacturers that intentionally go slightly oversized for a tighter fit.”

    In other words, if you buy a tubeless tire from another manufacturer, setting aside their manufacturing tolerences, if it’s designed for a 622mm (i.e. 700c) wheel it should fit – but we all know some tires are easier to fit and/or remove than others, and this applies to tubeless set ups too.

    Hi 456andy.

    Hi 456andy.

    Since my post in April I did some research and found out that the French compnay Hutchinson make Mavics tyres for them, I assume to Mavics specification.

    So I purchased a pair of Hutchinson FUSION 5 PERFORMANCE 11STORM and have used these without an issue, so far.

    Regards.

    The whole point  of UST is that it’s a universal standard. So yes, you can.

    Hi Roger. I have had a

    Hi Roger. I have had a similar experience with Mavic UST. I have a lovely new pair of Cosmic Pro Carbon SL UST wheels and the Yksion UST tyres they came with feel great and roll very nicely. However, I suffered a side wall burst on the rear tyre after 80km of use. I was running them at 81/82PSI, which is below the max recommended pressure so I can rule out over inflation as the cause and, on close inspection,  what looks like a nick from a sharp appears to be the culprit. That’s the way the cookie crumbles I guess, but I can’t help but speculate that the Mavics are a bit flimsy compared to some other tyres (e.g. my go-to shoe – the much admired and super relaible Conti GP 4000S II).

    I’m considering giving Schwalbe Pro One’s a go as they seem to get good cred but I’m a bit nervy about Mavic’s claimed ‘exacting tolerances’ and potential fitting issues (although I note bechdan’s first comment regarding tyre compatibility). I’m also in a bit of a quandry about any warranty issue I might breach by using a non-Mavic tyre and subsequently damaging the wheel – am I flapping over nothing?

    If anyone has run non-Mavic tyres on their UST wheels and would like to share their experience, I’d like to hear from you.

    1 – it makes no difference

    1 – it makes no difference what brand they are so long as they are tubeless compatible

    2 – all depends why you are using ust on the rear anyway. Ive used a variety of tyres on road bike sometimes as a matching pair sometimes different and cant say that I notice any difference in handling so long as they are of equal quality and pressure. The main advantages of tubeless as you are likely aware is self sealing punctures (to a limit) and ability to run lower pressures, some will say better road feel due to lack of inner tube but who knows. So if your main priority is puncture proofing then yes I guess it would make sense to have tubeless at front too, but for me Id want to balance the cost of a new wheel and new tyre vs maybe having to repair a puncture. Regarding running lower pressures – not everyone wants to do this or needs to, but if thats part of the reason for going tubeless on the rear then yes do so at the front too. Theres no right and wrong answer here.

    My own 2p – I havent gone tubeless on road bike yet as im not convinced that there is enough benefit and the tyres seem to have poor durability compared to tubed versions which usually cost less too.
    Off road however tubeless all the way……..
