Constant front tyre punctures

slc123 · October 2017

Hi all,

I seem to be suffering with constant punctures in my front tyre. I upgraded the front wheel following a crash and the other one buckled. I went for a fairly cheap option of the Mavic Crossride. Slightly wider than the standard ones but recommended tyres sizes were 1.4 - 2.7. I am currently running Maxxis Ardent 2.25.

I don't see any major problem with this setup, but since the change I manage to get a puncture every week. I've checked the inside of the tyre and can't see anything that could cause repeat punctures.

Anything else to look for?

Thanks

Have you checked the inside of the rim for spokes poking through the rim tape or any abrasive edges on the rim,

Also clean out the tyre carcass and maybe consider freeride tubes.

I’ve checked the inside of the tyre a couple of times and not seen any issues and the wheel is about 6 months old and can’t see any signs of spokes or rough edges.

I’m running tyres at 30-35 depending on conditions. Maybe I just need some better quality tubes that can handle it a bit better!

Go tubeless, no punctures.

It helps to identify the nature of the punctures, is the carcass being pierced by thorns, is it pinching on the rim?
I weigh 95kg and get pinch punctures under about 30psi if I'm riding hard.

I have also changed to branded tubes, usually continental or specialized, they seem more reliable than the generic cheaper ones., and i run quite lightweight fragile tyres, ron /ralph evo.

I run the same tyre, and dont suffer i am around 90 kgs and run about 35 in the front, the original inner tubes my bike came with were awful, i have since bought conti inner tubes that as of yet have not punctured.

It's worth scouring EbAY for decent inner tubes as i got 4 for £20 whereas the shop i got them from originally charged me £8 for one.

have you checked you're not pinching the tube when installing?

So where on the tube is it puncturing? by the valve, same place, pinch flats, through the tyre or on the wheel rim side?

That will narrow it down quite a bit!

As a few have said, go tubeless, its honestly the best thing. no more irritating thorns or road debris causing sore thumbs. I did loads of conversions for people when I managed a workshop.

why I am still able to sell MTB inner tubes is beyond me.

I think it is because people buy them.

Thanks for the info guys. So managed a couple of good rides with no issues. Of the two latest punctures one was in the centre and one was on the edge of the tube so didn’t feel conclusive. Will see how I get on and hope the last 5 were just a bad coincidence!

It's worth carrying a tube even when running tubeless. I've had punctures in tubeless tyres which failed to seal with the latex solution.
I never buy tubes though. I've found some many abandoned by the side of trails which just needed a patch.

So, as I am building a new bike I've picked up a set of Easton tubeless ready wheels. Any advice on the best valves/sealant or are they pretty much all the same...

Also, is a charge pump really necessary or standard floor pump going to do the job?

Thanks

Gorilla tape works and is the cheapest option, I used Stans tape which also worked well. Try specific valves for your rims if they make them then you’ll know they will fit, otherwise any universal valve should be fine. Hard to say if a track pump will be ok as all wheels and tyres will be different. I’ve always used a standard track pump, can be a pain in the ass sometimes but always managed to pump my tyres up, worst case stick a tube in, pump it up then remove it.

larkim · December 2017

I've never managed to make the inner tube trick work as I seem to end up dislodging so much of the bead from the rim when I'm pulling out the tube that I end up back to square one!

I've only ever used Gorilla tape and Stans fluid / Stans valves. I did need to make up a coke bottle inflator though as my single barrel Blackburn track pump failed miserably to get anywhere. Since then I've had a couple of successes with the track pump, but mostly needed a rapid inflator, so I made a fire extinguisher one.
