6" G clamp is all you need to break the bead on a divvy, Old plastic milk container for rim protectors, 2 or 3 good quality tyre levers. And a wooden frame to keep the discs off the ground.. Make a balancing rig if you want - I use a paddock stand - incidentally, the Avon Viper Sports that arrived yesterday don't have markings for the light spot on the tyre....

So that's what Jane was practising for? ..... Tell her it's not strictly necessary to lay the bike down to change the tyres! Honestly the lengths Yorkies will go to trev

Some good advice there GM. This is something I am going to have to do next time I need a tyre replaced.
Done loads of lightweight tubed tyres in the past, will have a go at tubeless next time.

I have used a couple of "g" clamps, the rachet types work well, you need to move them round the rim for them to work, I have also used a large vice, but now I have an air operated bead breaker, your better off with 3 tyre levers and as said cut up milk containers, though shampoo bottles are better, to get the tyre off, a couple of 2 feet 3 inch by 2 inch blocks of wood keeps the disc off the ground, this is essentail to stop it warping, I use something similar to this cgi.ebay.co.uk/tyre-bar-alloy-wheel-manual-changer-remover_W0QQitemZ170208004314QQihZ007QQcategoryZ30928QQssPageNameZWDVWQQrdZ1QQcmdZViewItemto remove the tyre, with this, it takes about a miniute, you put a bar in the wheel center, where the spindle fits ( I use a 3/4 drive extension bar), then hold the tyre and use the 3/4 bar to lever the tyre around and off, putting on, I just use 3 tyre levers and a couple of blocks of wood to keep the tyre in the center well, as i lever it on, I then use a www.marcparnes.com/ balancer, I can change a tyre in about an hour, including balancing and removal and fitting, though the first time it took 3 hours

Thanks for all that....had plenty of practice doing the tyres - eventually did about 10 last year having done first. Fiasco and Gpam and myself were blind leading the blind as we made hard work of it.
But, the technique is getting better.
Was after any comments rgds bead breakers, if anybody knew of any other suitable models. The G-clamps I currently have are either too small, or plastic so are not fit for the job. By the time I've got some the right size, I may as well get a proper tool for the job......especially if I can get one for £27......
Thanks for the comments........

I tried one i got for about £25 of ebay and it worked well this type cgi.ebay.co.uk/Motorcycle-Tyre-Bead-Breaker-TRIALS-MOTOCROSS-ENDURO_W0QQitemZ110238569973QQihZ001QQcategoryZ21669QQrdZ1QQssPageNameZWD1VQQ_trksidZp1638.m118.l1247QQcmdZViewItemyou have to move it around the rim, tbh, you can make one easly enough, if I was buying a cheap one, it would be one of these cgi.ebay.co.uk/SEALEY-TC960-Tyre-Changer-Manual-BRAND-NEW-BOXED_W0QQitemZ160225445431QQihZ006QQcategoryZ11704QQssPageNameZWDVWQQrdZ1QQcmdZViewItemor these cgi.ebay.co.uk/Bead-Breaker_W0QQitemZ230213674739QQihZ013QQcategoryZ25644QQrdZ1QQssPageNameZWD1VQQ_trksidZp1638.m118.l1247QQcmdZViewItembut I have a compresser, so I bought an air operated one, which works instantly, cost £160, but I have saved more than that, buying tyres when available cheaply, If you do a decent amount of tyre changes, then buy good kit, you can allways get your money back, when you no longer use it

The eBay one is the same as I was looking at........
The Sealey looks like a medieval torture implement......
The 3rd one listed is very similar to the abba bead breaker we used previously.
Thanks.

Clever idea. The Divvie side stand would do it but only with a helper. :-o
The lever types look good. My trigger type G clamps were not up to the job so last time, I used a garden spade wrapped in many layers of rags and rim protectors to protect everything. Lay the wheel on lengths of 3 x 2 to protect the disc. Put the well wrapped spade edge up against the rim and put your weight on it. The bead pops in.
Its easier with a helper to hold the wheel down but it works. The tyre is undamaged because the blade is protected with layers of rags.
Rim protectors are well worth having at £2 apiece, but string them together because the middle one will drop into the tyre just as you are about to pop the last bit over the rim. I also use three 18" levers so much easier than shorter ones. I got a jamjar of tyre soap from a car tyre fitters (who dont do bike tyres). They didnt charge and it will last me years.

I have just changed my R1100Rt rear to a Metzler, the stiffness of the tyre meant that it would not stay in the center well, which makes it impossible to get the tyre over the rim, I overcame it using clamps on the tyre to squash the beads together, but if I did'nt have the clamps, then it would have been a real struggle

I also find that to be the main problem when changing tyres.......getting part of the tyre to stay in the well so that you have enough play to lever another part over the rim. The use of g-clamps for that is a good tip. It is still depressing to find that the pro's (and other hams here ) can get by without resorting to such methods.....

I use my knee to keep the bead in the well - seems to work. Side note - Avon Vipers do not have a mrk for the light spot in the tyre - I fitted the front and it's taken almost 70g of weights to balance the thing.Gonna whip the tyre off and rotate it a bit methinks.....

After faffing around with a bench vice and g-clamps in the past, I finally decided to get the proper tool for the job and bought an Abba bead breaker. It's a sort of mini screw press, and is very effective - I've even managed to do a car tyre with it.
Not the cheapest though, at nearly £70 with carriage.

After much praise from Clive I brought one of those Sealey motorcycle tyre changers. £120 new from fleabay. Just done the tyres on the Tiger and took just over the hour start to finish. Great piece of kit.

HRHPenfold gave me one (ohh-err missis ) that he had made
