changing tyres

I always carry two spares (on rims) on long or remote trips but thought I'd try taking a tyre off a rim in case I ever needed to do it in anger (maybe to stick a big patch inside). Used the tyre pliers to break the bead, easy enough. Got one side off using a couple of tyre levers (although it did damage the inside of the bead a bit - although it pumped back up OK).
BUT - I tried to get the second side off the rim and jeez it put up a fight (I'm talking about one piece rims BTW). Tyre levers weren't much help as I couldn't seem to get in behind the bead to get a grip.
Anyone done this successfully? I assume it is possible? Or are one-piece rims only for the tyre-shop with the machine? Luke2

I have to agree with you mate. If you don't know what you are doing it's to easy to loose a few teeth or worse if you get it wrong.

one lever and a big rubber mallet. Brake the bead first and position the tyre in the middle of the rim. scoop in behind the tyre and pull down on the lever,then useing the rubber mallet belt either side of the tyre, around the tyre lever.This way you ending saveing the tyre but the rim bounces out.takes about 3 hits.

Yes it can be a pr**k of a job. The problem is you get pretty good at it when you are on the road and have 4-7 punctures, and then if you don't have tyre problems for 2-3 years you find that when next you have to take the tyre off the rim that you have forgotten how you did it last time!!
The 16 inch rims and large tyres are not the easiest to change-especially for beginners.
The bead breaker can be very cruel to alloy rims too.
Older tyres sometimes have brittle beads that don't seem to be as plyable as they should.
Best thing to do is to practise on your spare before leaving on the big trip.
Don't forget to use the dish washing liquid on the bead and rim so the tyre slides easily. When it is 40 plus the liquid evaporates too fast so I found the sun block or moisturizer to work more effectively!
A good quality rubber mallett is really essential to encourage the bead to go where it should over the rim!

Yep, and you need a rubber mallet with an extra long handle, cause you hit your hand on the tyre with the normal ones.

A good spray with Lanox as the lubricant makes things a little easier.

iff you had a mallet it would have made the job easier but iff you get a tyrepliers bull bar mounted tyre changer it makes it easier again & no need to lug spare rims all over the country just the spare tyre case 3-4 mins to swap a tyre & no sweat

I am assuming the real issue is breaking the bead on the last remaining side?

For if you can do that, it should then be easy to do as others say with the tyre lever & mallet.

Position the tyre & rim under under the towbar (or similar rigid part of vehicle) Place jack on tyre hard up against rim, sitting on bead/wall. Operate jack so that the top of the jack is pushing against the towbar sleeve. Eventually, after distorting the wall seriously, the bead will pop. I would also liberally apply a lubricant (I have used water + dishwashing liquid).

Once set free, you still may need to use the rubber mallett, because, if you have steel rims,the tyre maybe still stuck in other sections (probably rusted) to the rim.

Hope this helps. It was the solution provided to me about a year ago, off this forum, so I am returning the favour.

Another clue may be to get the tyre joint to break all the bead seals on all your tyres prior to your trip. Then, if you need to demount a carcass, it will be easier thatn if the tyre carcass had been there in situ for 2 years.

Cheers

Get yourself and R&R Beadbreaker tyre repair kit. Comes complete with a video. Do some practice before leaving on a trip. It works a treat, and forget about the rubber mallets and spitting chips etc. We took one to the Kimberley, compliments of a mate, and was glad of it.
Happy camping,
Mike and Jan.

thanks everyone. breaking the bead wasn't a problem (the tyre pliers worked a treat). and getting one side off was ok. but the second side - phew. I'll get the rubber mallet onto it for another practice. cheers.
