GSWC - DIY tyre change fail

Oh yes, and the expression on the face of our friendly Alaskan fitter when he realised he'd got it on the rim the wrong way around and would have to remove/refit was priceless. Even a big guy with pro-fitting kit was struggling and they were spoked wheels.:D

Pah, that's nothing, he should try changing a tyre on a Tomos!

diy tyre change,

While you have the scratched wheel, using the fancy wheel holder , have a go at re fitting the old tyre a few times, ideally using small tyre levers and the rim protectors pushed over an old t shirt strip, single layer,
I use mountain bike tyre levers and take very small sections from tight to the rim, the alloy or spoked wheels are not any more difficult on the gs, as has been mentioned get as much bead in the well,
and keep it pushed in as you pull the bead over with a lever, you shouldn't need a lot of force,,
its all a matter of practice, i fit and balance all my tyres including motorhome reinforced sidewall camping tyres with levers , it just gets easier with practice, not everyones idea of fun but rewarding in a way,,
good luck,, Roamer
 
The video shows him scratching the rim to bits,, but the basic idea after breaking the bead needs 2 or 3 bites on the rim protector to work the tyre past it on to the next one using smaller irons, i actually use plastic coated ones for the last bit if the protector is too tight to get in,,
 
I have used both the zip tie method and the method with tyre irons etc. Both work fine but the zip tie method is very time consuming. Using tyre irons properly ( a little bite at a time ) with a bit of experience is pretty easy and surprisingly enjoyable. A good tip- for rim protectors use cut up plastic oil cans- the rim protectors you buy online are truly crap.
 
when I used to change tyres at home, the biggest problem was keeping the bulk of the tyre in the well of the wheel,

even using a professional tyre changer on some tyres it can be difficult, only yesterday I removed an old and fitted a new BT021, and the removal was somewhat hard, because the tyre would not sit in the well, using the arms and an assistant worked well,

at home without an assistant or machine, I would use 4 quick clamps, and clamp the tyre together by the widest point, which made it much easier to keep the tyre beads in the well, then it was easy using levers and old shampoo bottles cut up as rim protectors, if it needs gorilla effort, then some things wrong,

another tip using levers is that you lever the tyre over the rim it was seated, not both over the one rim!
 
Don't totally understand this bit?

You lever the tyre out from both sides, so the rim is loose in the centre, then pull the rim through the tyre, rather than levering the bead over the rim, then trying to lever the second bead over the same rim, with the tyre in the way, which is easy on a machine but difficult with levers!
 
tyre levers

you spend all that money on the bike , then buy a bit of pig iron to use . buy a better lever and some soap its that simple, you have to practice to do it well without damage to the rim . you can push the first bead on by hand, take the second bead off with a rubber mallet and one lever. just practice on an old wheel and tyre

I have fitted many sets of car and bike tyres with the cheap thin 300mm tyre levers, and rim protectors, i did succumb to the better finished park tool mountain bike levers in both steel and a plastic coated version TL 5 and TL6, they do feel nicer,
as you rightly say its about practice,,
