I've just rotated the tyres, without the spare.
I don't have a hydraulic jack or stands so it involves, taking one wheel off, temporarily replacing it with the spare, taking off the next wheel, replacing it with the new one, then going back and replacing the temporary spare with the new wheel.
So, it involves 6 uses of the std jack to rotate the 4 wheels.
These jacks are really built for emergency use.
Does anyone think this is going to cause a problem? I'd hate the jack to fail on a dark night on the side of a country road.
I suppose this is going to happen every 20k too . . .
