Just changed the rear tyre - first time I've done that in 40 years!!  Just to share some tips really. The bead can be broken with a heavy boot or, as I found, G clamps.  These also help to keep the tyre in a position to insert tyre levers before removing the clamps and proceeding. As with refitting, a strong solution of washing up liquid and water around the bead helps removal. After doing all the usual stuff for removal and refitting, I found that the last bit is the worst. Again, I used G clamps to stop the bead popping out when getting the last bit to slot in. When I'm at a point where the tightest bit is, I used my 2 foot lever right in the middle and popped it in. Don't know if anyone else has used G clamps like this but it certainly worked for me. One other thing, when starting to remove the first bit of the bead, I found a piece of wood across the rim is a great way of achieving extra leverage.

and also helps the tyre slip round the rim next time it rains  pulling out the valve in the process, very difficult to get it all washed off.

beg or borrow some of the right stuff or french chalk

Tyre slipping round the rim..... really???  Have you had experience of this?  When I spoke to my local tyre place they recommended this method as an alternative??

Eek! A 2 foot lever can damage or even stretch the bead. Also, most detergents, especially washing up liquid, have a high concentration of salt. Not what you want lurking inside your nice chrome rim. I remove and replace tyres using a pair of 6" levers and a tin of baby talc (smells better than new rubber). As long as you make full use of the well of the rim there should be no need for brute force. For getting the very last bit of the tyre over the rim, a rubber mallet can be used to carefully knock it on.
As a struggling 18 year old I was taught how to change tyres by a pensioner with a Red Hunter Ariel. A single 6" lever was used and he binned my 2 ft tyre wrecker. It took the old guy 5 mins to fit the TT100 that I had been struggling with for the best part of an hour.
Worried about tyre slippage? Try security bolts.

Always remember to start and finish at the valve.

I use a proper tyre lube to assist fitting - cheap and a tub lasts for years.

Cheers guys.  My 2ft levers, used judiciously, are perfect for the job.  The only difference with these and smaller ones is it takes less effort to do the same job.  The salt content in the detergents aren't a problem as I have stainless rims and spokes, but I am considering getting a small tub of the 'proper stuff' anyway. Following on from Greybeard, when you're ready to inflate, just make sure the valve slides up and down easily.  As I was checking for pinches, I noticed a bit of tube under the bead of the tyre on the valve.  Making sure the valve slides up and down means that the tube is free of the bead at this point.

Good point, back in the day when tubes where common every where our tyre fitter had a threaded gizmo that screwed into the valve and had a length of fine chain attached, it allowed the valve to be pushed well out of harms way but could be retrieved safely. I have a similar tool but minus the chain

UPDATE - The Mitas HO2 I fitted to the back is superb.  Went for an 80m test ride and it went round corners like it was on rails.  No weaving over white lines or poor road surfaces and no 'squirm' under heavy braking.  Test ride was supposed to be 10m but it rode so well I couldn't get off.  Of course, this improvement might be because by previous Cheng Shin was knackered *eek*

Or because it was a Cheng Shin.  ;)

I have no experience of them. It was just a smart-idiot response from me!

Mitas are made in CZ by a company owned by Continental and started making rubber soles for a shoe company, Cheng Shin made by company owned by Maxxis in Taiwan and started out making push bike tyres . You should sleep better tonight knowing that useless piece of info ! *smiley4*
