Tyre valve replacement

[Gixxer 4 ever]

Let's get into a rageing debate - I say use WD40,it's much better..beleive me,I've tried everything and they don't seat,ever.

So you ride with them like that? Never I hope.They do go on but you have to be patient and deflate use more soapy water. Apply with a 25 mm clean paint brush. I apply the soapy water to the tyre before I put it on the rim because it is hard to lub the inside wall of the tyre once you have it on the rim. If this does not work pop the beads on the side you are having trouble with relub and try again. They will go on but you got to spend time. Only inflate to 40 psi when trying to install.

Yes,I ride with them like that - on my trials bikes.No,they don't seat,but you are welcome to come up and prove me wrong.When I got the TLR200 ready for it's first season I got a new tyre fitted and tyres swapped from KT250 to TLR at Cycletreads - oh,you won't get the front tyre to seat said I....no worries mate,we know what we're doing.After destroying a rim lock and bursting a tube he said I might have to ride for a bit to get it to seat.18mths later it's still not seated - do you think I should take it back?...

Please don't respond with more how too's,I have my own tyre machine with motorcycle adapters,done a few tyres in my time I have....

Aww c’mon I thought you wanted a rageing debate.

Ok well changing the tack (if not the tire ) my Beta had a tubeless Rear rim & they had just inversed the spokes & had a rim with a shoulder for the spoke ends. On My GasGas they use a normal rim with straight pull spokes & just fill the centre with Goo to seal the rim to make it tubeless.

So my question is why not the front as well?

CRC is absolute crap,WD40 is the reals mans lube,CRC is just perfumed kerosine - WD40 is...um...perfumed kerosine,but smells waaaay better! I like Vegemite too,Marmite is for CRC lovers.

I don't know if it's only trials tyres,but the tubless ones just won't seat with a tube.A lot of the modern bike riders will move a part worn tyre onto their twin shock,or sell them to a twinshock rider,some will seat,but they all have problems. I normaly buy a tubed tyre for a tubed bike on the road.

What about that Wynns stuff Viscolene? I was given some & it makes a good cable lube.

Pepsi vs Coke, Stella vs Becks

Though if you saw that telly program on marketing apparently all beers taste the same it's just an image you buy.


(the test was a bit flawed though)

That was not my intention. You have done all that can be done so I have to accept your comments. I started this thread to find out how often people pull and replace the valve steams on their road bike tubeless tyre rims. Can you comment on that? I have never changed one and have no problems but some people replace them with ever tyre. How hard are they to put in? Cheers

They should be replaced every time the tyre is changed,they flex as the wheel rotates and they start leaking around the base once they get old,this may not ever happen but it's only got to happen once to ruin your day (and tyre)

Any good tyre fitter will replace them each time without being told,I also recomend using metal valve caps instead of plastic,they have a better seal and will contain the air if the valve does crap out.

Thank you. That's what I was after. I felt this was the case but if no one has ever had a problem I would just leave it the way it was. Your right about the flat being a pain. One of the bikes I rode with to Paeroa this year had one. Big job to selvage. I now have a repair kit. Think I will change the steam when I do this tyre next month. Thanks

Yep,I had long stems on my 'Coon,with 6 on board and fully loaded for an Easter trip away when the stem broke on Good Friday,no way to get it fixed and just had to return home.

Relacing them every tyre change is a bit anal,but I wash my hands at least 20 times a day so have no right to comment.

On a slightly related note, I know you can put tubes into tubeless tyres on the BM - 4.00/18 style tyre, I guess that means 100 profile... is it possible to do the same to lower profile tyres?

Anecdotaly, from what I have heard around the traps over the years a tube can go inside a tubeless. Most tyre typews advise against this as it can cause balance problems at speed.

Once when I could not afford a new tyre after running over a screw so the pro's put in an inner tube on a tubless tyre on the Falcon. All good till about 90kms then it got a little funky in corners, And at 120 it was real funky on the straights.

I am no expert here but I remember putting tubes in tubeless tyres when I was hard up as well but the radial tyres moved around so much they soon leaked and went flat. Could have had something to do with the shingle roads and being young.

A tube is able to be used in a tubless tyre and If the tyre is rebalanced after the tube is fitted it will not cause any problem, a good tyre fitter will also use tyre talc in the tyre before the tube is fitted to stop the tube chafing on the inside of the tyre,some tyre companys used to recomend a downgrade in the tyres speed rating due to extra heat buildup though.

And if they put a tube in your tyre after running over a screw they certainly weren't pro's,amateurs is the word I would use.

Make sure the tube is the correct one, mate of mine had heaps of punctures caused by low profile tyre with regular profile tube, it was on a cage so maybe it is an unlikely event on a scoot.

[Motu]

Tubed and tubeless tyres can have different internal construction - the tubeless is less finished and often had ribs inside,a tubed tyre will be smooth inside - as Kickaha says use talc on the tube to stop chaffing,down grade in speed rating for sure.Fit a tube only if there is rim or bead damage causing leaks.
