guys, I checked the tire (pumped it up and used some soapy water to find the leak) and turns out that it is basically porous (is that an English word?), anyway, lots of small leaks through cracks. Therefore the fix-a-flat may not work.
So I want to use an inner tube but I cannot get the tire of the rim.....anyone suggestions how to? the local tire guy was hesitant to try to get it off since he thinks his machine will damage the plastic rim.
Thanks, Doekie
Break the bead on one side using a bottle jack and a bit of wood and the weight of a vehicle. Position the edge of the jack next to the rim. Then repeat on the other side. Then with one bead in the well of the rim, use a tire iron to lift the other bead over the edge of the rim - then work it around the rim progressively. The final bead can normally be worked off the rim by hand.
I'm sure youtube will have a video on how to do this. I've changed 12 ply landrover tires in the bush with this technique and a little sweat equity. It's all technique - not brute force. If you brute force it - you will break a plastic rim.
