I admit it, I can't change a tyre

[isuzutoo-eh]

:o Well, I can't get the damn tyre off the rim!

I have removed the valve stem (and lost it)
Soapy water has been liberally sprayed on the bead.
I have broken the bead on both sides using high lift and Land Rover mass.
I have two decent tyre levers, hooked at one end, flat the other.
I remember my Dad changing tyres years ago and he used a sledgehammer or mallet at some stage, so I have them to hand too :D

Is there a trick to actually getting the carcass off the rim?

I have been watching youtube videos and they all make it seem easy :mad:

YouTube - Land Rover Tyre Removal: By Hand
YouTube - How to change a landrover tyre

If it makes any difference, its a 5"x16" steel series LR rim, 205 size A/T retread with a tube flopping around limp inside it. The rim has a bit of corrosion where the bead sits and it was hell hard breaking the bead even with half a landy on a high lift bearing down on it.

I am up to the 1 minute point of the second video.

I don't want to pay a pro to remove my rubber, just want it off so I can clean and paint the rim :(

Thanks in advance for any advice

You have to remove from the correct side. It depends on to which side the well in the rim is located. They are off centre.

If I remember correctly, break the bead on both sides then bring the bead over the rim from the side to which the well is the closest.

Aha. See Repairing a tubeless tyre using a Bead Breaker (http://www.beadbreaker.co.uk/tubeless_tyre_repair_with_bead_breaker.html)

Go down to step 4.

Thanks Ron,
Having read the website you linked to, it seems my ample 60kg frame wasn't enough to keep the thoroughly age-hardened bead unseated so I was trying to stretch the bead. With high lift and rover again, I've managed to get the bead over the rim for about 15cm and now can't get any further :(
But now I can get a saw in to cut the b@$%^# up if all else fails :p

As you are levering the bead over the rim, you must push the bead into the well on the opposite side. Standing on the tyre whilst levering usually achieves this, even if you are lacking a little in the weight department:D.
You will only be able to take small bites at a time until about a third of the bead is removed. Once the front bead is removed, a slightly different approach is required for the back and this is where the hammer may come in handy.

I did 7 in one morning recently and some can be difficult.

Also... use 2 levers. One to hold the tyre from popping back into the rim, and the other to continue bringing the tyre out of the rim as you go around.

Another trick that I used to use back in the day, is dishwashing liquid spread on the bead or the flange on the rim works as a really good lubricant to help slip the tyre off the rim, and its water soluble to get rid of it afterwards.

Thanks Numpty and Slunnie,
When jumping on the tyre with it flat on concrete, there was zero deflection in the sidewall. The carcass has rigamortis :p
I used a fair bit of soapy water around the bead, I guess it helped a little but don't know.
As it currently stands, the tyre is still on the rim with one bead inside the rim. I give up for now. My folks come home tomorrow so I'll find out if i've been doing it all wrong, if not i'll cut through the bead and sidewall:twisted:

or.....if you want to come past pagewood......i can pop it off for you.......

I've always taken the tyre off a rim with the outside (when its on the landy) of the rim facing up. It goes back on in the reverse (outside facing up). The first vid does it the opposite by taking the tyre out of the rim.

As numpty said push the bead into the well of the rim. I push it in by standing on it. Then work at the opposite radius of the same bead to lever it over the rim.

When you get one side of the tyre over the rim the other side is easy. You just lever the rim off from the inside of the tyre. Difficult to explain.

Refitting a tyre I do it similar to the second. I throw the rim into the tyre rather than throw the tyre onto the rim. Also, I lever the bead onto the rim rather than use a mallet.

The soapy water is probably good for showing up leaks in the bead, but try just straight dishwashing liquid.
