Tyre removal with TPS?

[Bryn]

Got the new bike, and a set of new Tourances to put on it.... now usually I just drop the loose wheels in at work and our bike mechanic changes them in his lunch hour

He's not done bike tyres with Tyre Pressure Monitors before, although plenty of car tyres fitted with the same....

Is there anything he needs to look out for? I've read the valves are made of cheese or something similar

Just tell him to make sure he avoids the valve area when breaking the bead or inserting a tyre lever as the sensor unit can be damaged.

Other than that treat as normal but you might want to hang around to "remind" himand have a look at the unit for future reference.

"Because they are very expensive"

As above just make sure the first bit of the tyre to come off is by the sensor and that the last bit to go on is by the sensor as the tyre sits in the well in the rim and may exert pressure on the sensor.

I changed my own tyres a few weeks ago and as long as you are careful and remain aware of the need to keep everything away from them

Simples.....

Recently buggered mine! they are indeed made of cheese. I snapped the top three or four mm of the top of my valve so the little press down pin bit in the middle was standing proud. Its booked in for a new one (which won't be covered by warranty even though it just snapped off on the air line attachment) and will cost about £70.

When watling tyres removed it I noticed that the Nut that clamps it to the rim is just as soft and the spanner took a few chunks out of it.

Handle with care on any airline! I guess we get into the habit of bending our traditional rubber valves to fit the gauges / air hoses, etc. So don't be tempted to force these little buggers into submission, cos they'll just snap.



*on a seperate note ... ordered THIS the other day. Looks a good bit of kit to keep in yer topbox along with a puncture repair kit. Seems very robust and has a 90 degree valve attachment so none of the above problems when attaching to inflate. Only £30 and a good buy I reckon..*

Just proves what a waste of money these things are

Ask Mad Moose about changing tyres with a TPS. The look on his face when he thought he buggered it up was priceless only matched by Allycam when Moose said, "no worries mate, I just stick an ordinary valve in"

 

[Giles]

yes ... if it wasn't for the fact that my dashboard is constantly flashing me a warning, I'd leave the rubber valve in.

 

[Bryn]

Think I need to stand over him while he does it with a big stick then

He did manage to put a tyre on one of the 'work' bikes backwards not so long ago

Good advice - the gravel on the Dalton and Ruta 40, in places, is the size of railway ballast and one of the Globe Busters guides I met was telling tales of trips over the years where several riders with spoked rims got a piece of ballast flicked up into the gap between the spokes...

The ballast spun round inside the wheel rim - a bit like a hamster on a wheel - until it had struck the tps valve. Being so fragile they'd broken very easily...

The advice I got was remove them if you are going off road as the "conventional" valves are not only shorter but more robust...

True, the warning light does stay on - but it really isn't that much of a nuisance...

I have to say, this is the reason I never spec'd it in the first place. I've had calipers fall off the bike after tyre changes, never mind trying to explain about taking the tyre off carefully!!

Good luck Bryn!!

Suppose I could bite the bullet and let Pidcocks put the new tyres on when it goes in for a pre-trip 6k service

Bryn, How far are you from Oakham ?

BATS Tyres are fully compliant with tyre pressure sensors / tyre changing. You can even stand right next to him when he does it if you like !

Just put a pair of BW;s on mine for £225.

About 20 miles ....suppose I could strap the new ones on the back and have a ride over... as long as they don't mind fitting tyres not bought from them

Do you know what the fitting charge is ?

Only charged me a £10 all in for fitting but I would ring first to be on the safe side. Its only a 2 man and a tea lady operation but I have used them for a few years and will always recommend them.
