Tubeless is a good idea but.......

On my gravel bike I will be swapping the tyres regularly. Smooth for road use and treaded for off road use. It would be a right pain having to wash out and refill sealant every time. As I will take the gravel bike away on the MH with us this could be 5 or 6 times a year.

This is my first flat in over a year with the Gatorskins on my road bike. Think I can cope with an innertube swap that often. It's not as if I have to go cycling....
:unsure: Don't you need two sets of wheels? Or are you swapping more tread types than that?

On our gravel bikes we rode a tyre that would cope with all road and off road riding, this was the advantage of such bikes, a mix it up type of ride, going tubeless on these bike with this combo is a great concept....then some B*****d pinched our bikes.

I've used tubeless for about ten years on my MTB's. It can be a swine to initially seat the tyre but then I bought this bad boy pump ....

Great piece of kit.

No punctures since I went tubeless - in fact last year on a ride I pulled huge thorn out one the tyres, heard a bit of air escape and then watched it self seal and rode home.

Hi everyone, some great advice on this thread ref going tubeless. It really is the way forward for MTBs, hybrids & eBikes, perhaps less so for a pure road bike (racer).oo
I've been tubeless for almost 20 years on the MTB, since the early days of the Mavic UST system. Could count the number of flats I’ve had on less than the fingers on one hand in that time.
As recommended earlier in the thread I only use Stans Sealant, and use about 100ml in the front and 130ml in the back. I’ve tried different brands but none work as we’ll as Stans. It does dry over time and you’ll end up with the latex golf ball, so will need topped up every 6 months or so.
The biggest issue I’ve found with seating the new tyre onto the rim is getting enough air in to ‘pop’ the tyre onto the rim so it can lock into place. The best way to get over this is to use compressor or a device like the Bontrager pump mentioned above. Key to this is to remove the valve core which allows much more air flow into the tyre, much more quickly.
I’d be very careful not to inflate the tyre too high as you can blow the tyre off the rim. If this happens it can stretch the tyre bead which means it won’t seat properly. Don’t ask me how I know this!
Another tip is to unpack your new tyre, unfold it into shape and rest it against a radiator overnight so that the heat help any creases come out. This can help it seat & seal first time.
Finally, if you’re still having troubles you can pop a tube in and then fit the new tyre. This will lock it on to the rim and help it take its shape. Then just pop one bead off and take the tube out before adding your sealant.
I use a Stans injector to add the sealant into the wheel through the valve once you've removed the valve core. They cost about £10. Rinse with water after each use to stop it clogging up.
Finally pop the wheels back in the bike and spin them round to displace the sealant around the wheel.

Happy riding!

Finally (I promise!), if you do stick to traditional tubes and get a puncture, make a note of where the hole is in the tube and check the area of the tyre where the hole would have been.
Also, run your finger gently around the inside of the tyre to make sure whatever caused the puncture is not still stuck in the tyre! If you don’t it.l just cause more punctures.

I did....didn't feel or see anything. Second puncture occurred so had a better look. The small piece of glass was stuck in the outside of the tyre and only poked through when I rode the bike. So check both sides of the tyre....

Problem is the tyre often rotates as you take the innertube out so you need to check the whole tyre for whatever caused the puncture.

You can use the valve as a reference point.

I’m now full of goo, and tyres are still round, so it must have worked.

Next question. What pressures are people running on their MTB tyres?
Mine are 29” 2.6.

Never put a pressure guage on any of our tyres, prefer to use hand pressure to press into tyre...we live in a dry but rocky area rarely see mud.....so pressure can be adequate to provide comfort with the need to protect the rims...I would increase pressure if doing a hard surface ride....Maxxis 29" × 2.6" front and 27.5"+ 2.8" rear...

Almost a N00B !
Recommended range of tyre pressures should be marked on the tyre wall. Softer surfaces you want to be close to minimum perhaps a couple of psi higher rear than front as the rear takes more weight. Too soft and the tyre could disengage the rim when cornering or on a rutted surface but too hard there won’t be enough surface contact so you slip

Or see which contractor is flailing the hedges take a picture and then one of the road and when you get a puncture e mail the contractor with the picture and the bill. They will pay up 99% of the time as they are supposed to employ a sweeper and collector as well as the blower to get the thorns off the road but most times never bother but will charge for and take a chance on punctures

I use a digital pressure gauge as the thumb squish is incredibly inaccurate.
Anything from 15 to 20 psi in the front, and about 3 to 5 psi more in the rear. I’m using Maxxis 29x2.5 WT tyres.

My thumb squish is about as accurate as any tyre pressure guage.....35 years of squishing both nationally and internationally....want to put it to a test? Anytime....:LOL::LOL::LOL::LOL::LOL::LOL:

I think you must be lighter than me, so I’m running 24psi front and 30psi rear and that’s softer than I'm used to. Does give good grip though. I like 👌🏻👌🏻

6’1” and 75kg, maybe 80kg with all my kit on. Not been riding anywhere toorocky but would maybe add a bit more if we were.

Thanks. As I thought. I’m 6’4” and 92kg naked. Would think 100kg in riding spec.

Every day since going “tubless“ I’ve been out to the garage to check, and they are still inflated. Still feels odd, but I’m looking forward to this weekends outing on it.

Remember to ensure that your valves are not at the bottom of your wheels when storing your bike for more than a few hours.... They will start gunging up and make topping up with air difficult.

Also, many tyre sealants need topping up every 6 months or so....
