[Closed] Sick of pinch flats - Dual Ply, Tubeless or alternatives?

I didnt fancy tubeless until I used it. Just saying.

Why put super heavy draggy dual ply tyres and still risk pinch flats when you can go tubeless use normal tyres save weight and have no pinch flats.

Tubeless really is easy. I was sceptical too, but over a year without a puncture has convinced me.

more pressure in your tyres? I run 35-40psi and weigh 60kg, I only ever pinch flat if a make a bad driving mistake.

I am not a subtle rider and used to get pinch-flats EVERYWHERE, even when running 40+ psi (it's not weight - I'm 62kg - I'm just shit).

Changed to tubeless and Specialized The Captains and now bounce happily from rock to rock at about 25 psi.

Could I ask why not? It will, pretty much, solve your issues

I think it's because I've seen lots of people having issues with burping on tubeless. Is it just different valves and some gunk I need to go tubeless? I've got tubeless ready rims and pretty sure the tyres are too.

I was very sceptical of tubeless. Didn't like the idea of filling my tyres with sealant, the associated mess etc, faff of fitment. In the end I bit the bullet and went for it and am extremely happy with the outcome. Just pick rims and tyres that are renowned for their tubeless ease. I'm on Stans Arch Ex and Maxxis High Roller 2's, tubeless'd a cinch. Previously used the STW approved purgatory/butcher combination and they were dead simple too. A side benefit is that I don't chop and change tyres all the time now, just ride what I've got - this has genuinely improved my riding as I no longer try and make up for poor skills with different tyres.

I say let the op put some dual ply tyres on and see what difference it makes. If adding an extra 800 grams to each wheel doesn't convince him tubeless is the way to go, nothing will 😉

Tubeless is definitely the way forward, or as I've done tubeless with Schwalbe supergravity tyres for extra protection.

Burping can be a couple of things, some rim/tyre combos aren't great, but it's mostly just running pressure too low.

What rims/tyres have you got at the minute?

I used to get loads of pinch flats. Changed to 819 mavic tubeless and still got loads of pinch flats. Mostly from going too fast, bashing rocks and the rim putting holes in the tyres.

I now put more pressure in my tyres and check it each time I ride and do not get so many flats. I have never, touch wood, got a pinch flat on my stans flows either on my hardtail or full-sus though.

I too was plagued with pinch flats on mtbs and CX. I realised the errors of my ways and coverted to tubeless and feel born again! Hallelujah!

I certainly wouldn't ever ride offroad with tubes again. Yes, you do usually have to faff about a bit in the garage to set them up and yes, once in a blue moon, you'll have a problem on the trail (about once a year for me) that'll require a tube to fix but compared to the endless faff of pinch flats and normal punctures I endured, it's so much better.

Currently running Bonty XR4 on Mavic XM319

You can still pinchflat with tubeless mind! Success rates depend a bit on your existing wheels, there are some that just don't work well and some that work superbly. I was never happy with ghetto tubeless on my 717s frinstance but other folks have been

TBH firing in more air is the quick fix

You can but it's much less likely - I haven't done it yet (I know, I've jinxed myself now..)

I thought I was a late adopter of tubeless and I swapped over five years ago!

I've seen lots of people having issues with burping on tubeless

I think this was mainly in the early days when people were trying to convert their normal rims on the cheap. With rims designed to be tubeless ready its very easy and faff free.

I've been tubeless for some time now so after spending a fortune on MAXXIS EXO tyres I set off for the Alps, where I went thro 3 rear tyres in 2 days.

I then bobbed my Minions on which are dual and then stuck a MAXXIS DH tube in the back for good measure. they were fine.
Heavy but fine as I was descending.

A mate ran some Magic Mary's tubeless and had no issues, had I put the right tyres on in the first place I'd have been sorted I just went thinking that because the tyres were ok here they would be there but they weren't.

As for not going tubeless, your obviously not getting enough punctures,

I found I was just a likely to pinch using tubeless. Personally I think the best thing for me to avoid pinch flats is to put more pressure in my tyres and check the pressure before I go out. Tubes do not burp so avoid losing pressure during a ride.

Not sure if tall thin 819 rims are more prone to pinching the tyre than Flows or if flows are less prone to burping.

Tubeless was a pita at times for me, living in flinty Kent until I bit the bullet and invested in tougher rear tyres - specifically Specialized's Grid carcass.

Since then I've been more than happy with the results.

Right with 319 rims you'll need to run a fabric rim tape around the first to bulk out the profile, and then some Stans tape to make them airtight. Get some valves from superstar (the have a round bung which makes them easier to seal) and some goop.

You'll probably have to run them with a bit of pressure, start at 25psi and see what happens, as it's a big fat tyre for a pretty narrow rim

ahh avoid pinch flats bend the rim instead you know it makes sense 💡

I've not bent or even dented a rim since going tubeless around 5 years ago (actually probably more than that)

You don't need DH casings, I'm running tubes still with either Maxxis Exo sidewall protection or Schwalbe's Snakeskin version.

Hardtail, rear runs at 30psi, front at 25psi....I ride all the usual South East single track and Welsh stuff, book on the odd uplift day and haven't punctured in any form for years.

I have an attic full of thin walled 'normal' tyres that I used for years and did get flats with...once I decided to spend a bit more on quality casings the flats stopped.

Exo or Snakeskin is the answer!

I wouldn't run too low pressures if you're pinching routinely, particularly with XR4s, as they're pretty lightweight. start with 30 or 40, and prove whichever tubeless system you run first. experiment with low pressures later if you feel the need.
buy the weldtite or genuine innovations tubeless repair kit too.

i used to pinch a lot too. hardtail. ended up using the maxxis freeride tubes in the rear for this reason at 40psi. pricey and heavy. ghetto tubeless now and happy with the grip ( despite sticking with higher pressures there is still an improvement ) and in particular weight and therefore acceleration/braking/cornering.

I went Tubeless earlier this year and have have one big problem and that is all the waiting around on the group ride when your non-tubeless mates are faffing around fixing pinch flats. Anyone got an idea how to sort that one?

Take a gun and shoot them. It's natural selection.

Yeah. Be the tubed guy sitting waiting for tubeless mate who's burped tyre off rim, and is now using that archaic flawed tube to get him home. Or sit behind the non sealing tubeless that's spraying latex all over its owner, his bike and kit as he rides along in ignorance.
. I've seen more tubeless failures than I've had tubed punctures in the same time.

Or sit behind the non sealing tubeless that's spraying latex all over its owner, his bike and kit as he rides along in ignorance.

It's so much funnier when your sealant is spraying over your mate/his bike... 😉

(that sounds quite wrong... 😆 )

Never fancied tubeless looked dodgy to me , 3 pinch flats on Cutgate and friends cursing me , Stans kit bought tubeless done , never looked back ,22 minutes quicker this time around on Strava 😉

Double post fail !

For the last three years, my go-to configuration on all my bikes has been dual-ply Maxxis running tubeless. It is the only thing that withstood the rocky impacts on the rear.

One particular set of rims don't seem to like DP Maxxis tubeless though, as I've blown the tyre clean off the rim on landing small jumps twice now.
Once - I'd have been put down to random failure.
Twice - means I need to find another option. Currently waiting for delivery of a Supergravity Mary.

I've tried Schwalbe snakeskin and Maxxis Exo. Neither have been up to it IME as I've been pinchflatting straight through the tread at 30-35 psi (cuts beyond the healing capacity of the Stans).

I will be installing Procore on the rear end of my FS bikes at the first opportunity.
Tried an early twin-valve prototype Procore last year in Finale and was the only one in our party not to pinchflat all week. Despite putting some big dings in the rims, they held up perfectly.

How heavy are you guys that can run such low pressures?
I'm bobbing on 16st fully loaded 🙄
Have managed to get through 8 months with only one puncture due to a Lakes water bar.....
If I were to go tubeless what would you suggest? I like my Maxxis tyres btw....
I have over the years witnessed the faff associated with tubeless and cannot be arised with the idea 🙄
I cannot afford to experiment like some ^^^^^^^^^^ I need something that works hence sticking to tubes and enough air for the terrain to be ridden 😉

I noticed that places with spiky pointy rocks need much higher pressure than more dirt based trails. With stronger than basic single-ply tyres I'd recommend riding dirt/roots at about twice your weight in stone in psi. With spiky rocks I'd be going a good 25% higher at the back and a bit higher at the front too. And that's assuming rims of a decent width to stop burping.

So in the Lakes on Maxxis Exo tubeless at 16 stone I'd recommend about 32psi at the front and high 30s at the back.

Saying that if my local trails were rocky I'd be getting ProCore as soon as its available!
