Brompton tyre choice for easy removal- advice please
ni...@albion-manufacturing.com
I'm having a nightmare repairing a rear puncture on my Brompton.
The rear tyre (Schwalbe) removal is hellish and once the tube is
fixed, trying to refit the tyre without pinching the tube is
purgatorial.
I've had to use steel tyre levers which isn't good on aluminium rims.
What is the best choice of tyre for easy removal?
I am quite experienced in bike repair but this is proving extremely
challenging.
Any advice gratefully received.
Thanks.
Nick

I've had that in the past with Marathons on the Brom. But the most
recent ones (with the new tread pattern) seem to be a lot less, errr,
/gladitorial/ and I can get them back on with just thumbs.
That's on the same rim as I'd previously used during turn-air-blue sessions.
Pete.

If you haven't got one already, invest a few of the BRITONS' pounds in a VAR
tyre lever:

Effective against even the most stubborn tyre (406 Marathon Slicks, in my
case).

Aren't you approaching this from the wrong angle, if your head hurts
because of repeatedly banging it on the wall the solution is not a
stronger painkiller.
Surely you want a less puncture-prone tyre rather than an easier one
to fix?
The answer to the latter problem is Schwalbe Marathon Plus, which are
often a sod to fit but you don't need to do it very often.
Of course, if you've already got M+ then please ignore me.

can't answer your tyre choice problem but can point you in the right
direction about dealing with tyres. With one wire of the tyre over
the wall of the rim you should be able to rotate the tyre wrt the
rim. If you can't, examine the rim tape to see if it is overlapping
or otherwise proud. Examine the edge of the tyre for excessive
rubber. If there is still a problem then dust the rim tape and the
tyre with talc/french chalk. Without puttinng in the tube, practice
getting the other wire over the rim wall. Massaging the tyre from
both sides towards the wire to be lifted. Start the massage from
180deg away. Use a bit more powder if it helps. Once you've done
this a few times, dealing with the inner tube is easier.

Regular tyres maybe, but you don't seem to have tried some of the
super-tight tyre/rim combinations out there these days. Standard
practice just doesn't work, pro mechanics break levers, bruise thumbs
and sweat blood trying to get them on.

Have you put the part of the tyre which is over the rim deeply into
the well of the rim. This makes it a lot easier to get the rest of
the tyre over the rim. It is particularly important to do this with
small wheels, where there is much less to spare due to the far
smaller circumference.
I used to struggle with tyres on Bromptons, but once someone pointed
this out to me they became much easier, to the extent that tyre
levers are not really necessary to refit many tyres.

The worst rim I've used for wired on tyres was a Super Champion Mixte,
it had high walls and was able to also take a tubular tyre. Every
tyre was a pain to get on and off and each tyre change seemed to
present a new problem to sort out.
Solutions;
Use fabric rim tape, cut short so ends do not overlap.
Get tyre and rim spotless with washing-up detergent and nailbrush.
Use plenty of french chalk. Rim, tape, tyre, tube.
Scrape/rub off protruding rubber on tyre wall edge around wire.
Use punch to seat tall ferrules.
Ensure tyre can rotate on rim before inserting tube.
Before attempting to get the last of the wire over the wall, massage
the tyre from opposite to the opening, pulling on each side as you are
dragging the tyre around, at the same time pulling at the gap (with a
lever if liked). this will hold the wires in the middle of the rim
giving more play at the final fitting arc.
Forgot about the tensioning of the wire when centralising them by
massage. Specifically dusting the rim and tape is something which
appears to be ignored.

That makes sense. I had a p*ture last week - fixed it and needed an iron to
re-fit the tyre, which pinched the inner so I had to take it off again.

Fixed it and this time the tyre went back on with no trouble, no need for
irons and no pinching.

Dont use tubs. Two holes with every stitch. tttt

I'll try the talc/chalk method and seeing as there's not much life in
the tyre left will look for new style Brommie ones.
I stopped using talc in tyres a while back as I didn't see much
benefit but in this case it will be beneficial.
My method for removing tyres seems to work on 99% of the other bikes
I've worked on but as you say, perhaps it needs some refinement in
this case!
I don't know about the headaches but I really was ready to set to the
bike with a large hammer!!
I may ask for some new levers for Christmas as I have snapped far too
many plastic ones just recently....!
Best wishes,
Nick
