Pic. pinched from another site as mine didn't come out too well.

I have two sets on rims at whatever pressure they were last used at and sat outside in the cold weather.

First thing is to drop the presures after checking them over. There's no way I have room to store a dozen wheels inside, not and still have someone else do the cooking, washing, ironing, cleaning, shopping and other womanly duties
Another point is the 20oC for 24 hours before fitting. Unless we have a particularly warm summer, again, there's no-way.
Anyone else aware of this and if so, how do you deal with it?
