[Closed] Is this a warranty case?

25psi is pretty low, you could easily have done those in town. User error IMO, not that it can be proved either way.

This is on a new bike/wheel yes?

No chance. That's damaged by something sharp/jagged/pinty stabbing into it. Could have been damaged in the shop you bought it from, but surely you'd have seen the holes when putting it on? Warranty is for defective manufaturing, not other damage. The only way you might have a case is if other tyres on other bikes are like that, indicating a issue with the factory tyre fitting machine, if they use one. And if a bike shop let a new bike with a tyre in that condition go out of theirshop, they desrve to go bust. But I'm going for damage caused on ride, personaly.

Oh 100% percent. Clearly a manufacturing defect.
In fact i would demand they replace the whole bike with the next model up.
Bugger. Too slow

Tat type of tyre should be able to take low pressures though - it is a crossroc.

Its either been poorly fitted, or you scuffed something sharp and punctured it, depends on the shop but I imagine many would say punctures are not covered under warranty...

These marks occur all along the tyre at regular intervals, on both sides, so I don't believe they were caused by something sharp as the damage is too repetitive. I didn't buy the tyre separately, it came with the wheel/bike. 25 psi may be low, but not for a tubeless which I we're let to believe they were.

i imagine they damaged it putting it on or removing it but I have no idea how you will prove it so ask and then move on.

Is the wheel set up tubeless - tape and valve? I presume not, given there is a tube in it!

It could be that a bit of latex will sort the holes in the tyre, and TBH, if it was sold as TL ready, then it should be set up tubeless for you ready to ride.

The bike is this http://www.stantonbikes.com/content/slackline-631-available-now

The wheels are advertised as tubeless and it transpires they are not! I think that's the biggest gripe I have now come to think of it.

Do you mean you expected to receive them setup as tubeless?

The wheels and tyres shown there are potentially tubeless - ie they are suitable for tubeless applications. Doesn't say they will be supplied already set up with a tyre mounted tubeless (unless you were told differently by someone).

Still worth setting them up with a rim strip and valve and seeing if a bit of Stan's fluid will seal those holes and get them going.

Martin the advert says

Mavic Crosroc tubeless wheel and tyre combo

the advert it wrong.

Not really, as it is a tubeless wheel and tyre combo.

Just hasn't been set up.

IIRC, the Crossroc is delivered with tubeless strips and valves

Damage there doesn't look much like factory to me, but the moulding does look a bit rough, so wouldn't rule it out 100% if they had seen other similar problems (?)

you could email gbcustomer.services@mavic.com with pics and ask for an MSC opinion

It would possibly have been better to call it a 'tubeless-ready wheel and tyre combo', to remove all chance of misinterpretation. You clearly thought it was going to arrive with latex fluid sloshing around in the wheels.

My reading of that was slightly different.

Going back to the original tyre damage, can't see exactly from the picture, but have those scrapes damaged the bead in each location?

Mavic Crosroc tubeless wheel and tyre combo

Ditto if i read 20 gears I would expect 20 gears not the potential to be 20 gears if I made it so.

TBF I'd expect it to be set up tubeless.

However tubeless tyres can't just be run at any pressure you like without damage - if these had been set up tubeless you'd have similar or possibly worse damage.

25psi in tubeless mtb tyres is fine and shouldn't cause damage. The wheels should have been provided tubeless. Some of the replies above are typical stw!

I'd definitely try Mavic, it's not damage from something sharp on the road if it's both sides at regular intervals, unless you rode hard over a set of closely spaced sharp things! (are you 20 stone and smashed into a set of steps?). Perhaps your pump guage is wrong and they were sitting at 15psi or something?

The wheels should have been provided tubeless. Some of the replies above are typical stw!

Not sure what that means, but I honestly thought the description would mean they were ready to be setup as tubeless. As in, if I got them and they had a tube in, then fair enough. General consensus suggests I am wrong in this assumption, so I gladly accepted my wrongness....in both this matter and life 8)

How else was the damage caused? I'm only 80kg and I've had flats running tubeless under 30psi. PLease don't tell me it's my lack of skills.

He's ridden 6 miles. Perhaps the damage was caused by a number of impacts over those 6 miles rather than in one incident (why on earth do you assume the latter in any case?)

Weight definitely a potential factor.

Can I share your wrongness, Jamie? 🙂

Perhaps my expectations of what mail-order bike suppliers will do is waaay too low...I'd have been happy with just a rim strip fixed and valve supplied.

Wait a minute, so some people think that if a wheelset was described as tubeless, they would expect it come with a tube? Seriously? How would you describe a wheelset which doesn't come with a tube?

If I told my friend my wheels were tubeless, I would think they would be utterly moronic if they then followed up my statement by asking me if there was a tube inside my tyre!

Probably best to go and have a rant at Stanton at this point rather than using your energy on forum randoms. Let us know how it goes, I'm genuinely interested.

Well, even Mavic describe it thus:

[/url]

...but, as per Martin. Better to raise your concerns with Stanton, or whoever you got the bike from.

Your sincerely, Moron.

The marks around the tyrewall have been caused by low tyre pressure.

I've seen it before on non tubeless tyres that have been run at very low pressures, it's easy to reproduce and is caused by the tyrewalls "creasing" as the wheel rotates.

Is there a minimum pressure printed on the sidewall, if not take them back?

Jamie your post is so misleading. You haven't read my posts throughtly obviously. The link which I supplied earlier, the advert which I read, describes the tyres as

Mavic Crosroc tubeless wheel and tyre combo

I think you owe me an apology.

In fairness to Stanton, they supplied tubeless wheels/tyres as specced, they just gave you tubes as a bonus.

. NOT what the Mavic wheel website says.

Get over it and move on...

It makes no difference what the website says, that damage was caused by low pressures and the tyrewalls "creasing" up. Speak to Retailer/Mavic.

Minus the values, tape and sealant.

Those sidewall marks are the same as I got running tubed tyres at too low a pressure.

Edward 2000 - you don't get sealant, people have already commented that the wheels are shipped with a sealed pack with valves and tape, along with the tubes fitted as you've received - you're kicking off because the sealed pack is missing, which is unfortunate but obviously a minor mistake that could have happened at stanton or the retailer, and does not deserve the fuss you're making without having spoken to them about it first, in fact I think the way you have handled this is very unfair on stanton.

in fact your whole approach to it, and others here who have tried to advise you perfectly reasonably, makes me suspect that the 'smashed into a set of steps' or kerb is an accurate scenario.

apologies for saying it like I see it.

Depends - if I had bought tubeless/tubeless ready/whatever wheels, and received tubes instead of tubeless valves - meaning I had to go and buy valves for them - I'd be annoyed.

Is there a minimum pressure printed on the sidewall, if not take them back?

This. I don't think I've had a set of tyres that quote the pressure range to go as low as 25 psi. Pretty sure my current Specialized ones say 35-50 psi. If they do quote a pressure range and you are outside it then it's your own fault imo.

25psi in tubeless mtb tyres is fine and shouldn't cause damage

Tubeless tyres aren't magic. You run low pressures in them and hit something hard it will damage your tyre and rim as per the pictures above. The advantage you have is that you might not get a pinch flat.

Well.. I reckon those regular marks are caused by it being damaged/scraped when it was stored folded.

on the folded ends, scraped along a floor or a wall, when the bead was flattened and exposed. Probably ziptied flat in packaging.

Conti's come in a box, don't think Mavic do..

Absolutely nothing to say that they will be delivered tubeless. Implications are nothing.
That aside those tyres have been damaged. They won't have come from the shop like that, the purchaser would have seen that. You did have a quick look around the bike didn't you? Mail order? Cannot imagine that anyone would check a bike for transit damage so on this issue I reckon that's the owners problem. Thre may have been pre or in transit damage but there is no proof. Write that one off as failure to accept the bike properly.
You may get some come back but on both issues I reckon to be fair it will be excessive good will not obligation.

AFAIK most bikes come with tubes, even though they may be tubeless ready - this is because tubes will stay up will in the box/shop/warehouse etc; whereas tubeless often won't.

Does look like damage caused by low pressure in the tyres!

I think you owe me an apology.

I think Beyonce should go out with me.

Sadly, in the case of the latter, neither are of these things are going to happen.

I wouldn't expect any new bike to come with tubeless as standard- not everyone likes tubeless. Saying that a wheel is tubeless and a tyre is tubeless doesn't imply that they're set up tubeless- means 2 different things.

Back to the OP, usually I'd just say that's tyres that have been mangled against rocks. But in such a short span, you'd have to work pretty hard to do so much damage so I think you can't rule out defects. But I do think it'll be impossible to prove anything.

Jamie I think you owe Beyonce an apology

Surely it is Beyonce who should be apologising?

I think you're on to something there, Tracker1972.

ALL THE SINGLE PLY TYRES.. All the single ply tyressss. Uh uh oh.

Pinch flat ...

I ran 20psi in Hans D's at Coulags and nipped my bead/sidewall exactly like this. I hardly felt it and it was my own fault for leaving the house with such a low pressure. I normally run about 23 24psi-ish on the climbs over there but I thought I'd go a bit lower to prevent pinging off everything in sight.

It could happen on the first off-road corner on the first ride. It could also happen a few months down the road. It's tough luck. Order a new tyre and bin that one.

Or you could sew it with fishing line and smear Aquasure on both sides before running it tubeless with no leaks. Mine sealed fine with Stans after carefully trimming it at the rim side of the bead. If you're a skinflint,that is :O)
