What have done towards your prep?

[Prepper1]

Changed the cracked valves on my bug out trailer wheels, with a spade ( to push the tyre off the rim, dont use a sharp one or you may slice the tyre.) and a pair of pliers to remove the old valves.

I have incidentaly removed tyres with an old worn smooth crow bar... hard work as its not the right equipment obviously but do able.

You have to deflate the tyre first, lay it plat on the ground, insert the spade under the rim onto the metal beading that runs around the tyre inside as thats the strongest part, stand on the spade whilst leaning on the wall and jump up and down firmly but not enough to bounce the spade off the tyre, and then squirt washing up liquid and water into the recess in between the tyre and rim as this helps lubricate matters which helps the tyre slide off.... takes about 5 minutes per tyre.

I suppose it helps, having years of not being able to afford to take cars to the garage etc... you learn how to do things yourself.

I do ALL my own repairs.
