User Manual, Page 169: "Tyres which are not fixed to a wheel trim should be stored upright."

Is that so? I placed my tyres the opposite way, the first one with one side on the ground, and the rest of the tyres on top of it, shaping a stack...

I would think leaving them in standing position would somehow make them lose a little their circular shape, without a wheel inside...

What do people think about this?

I have read before to let out a little pressure and stack them in seperated layers

I stack them verticaly....standing upright ...IIII........BUT I inflate them to the max figure as stated for the max load of the car as per the fuel filler cap.......I also clean/polish them and put wheel/tyre dressing on the rubber.....and they go in a big cardboard box that I made for them.

EDIT...........oooopppppppssssss........you're talking about tyres removed from the rims.......I would store them so that they are not taking the other ones weight!

Store mine on the side, inner edge down. Do not stack one on top of the other.

Lots of debates on this but considering a lot of pre- registered or even year old second hand ones have probably sat static in a field for six months I cant see how it makes a difference. Not attached to the car they must have hardly any force on them.

I am pretty sure rubber molecules dont re-align if orientated the wrong way!

Sorry but re-aligning rubber molecules in a tyre ha ha nice joke.

The main thing to worry out would be mice or other rodenty things and sunlight.

Realisticly your more likely to stab something like a screw driver through them than do any serious damage to them just because of how you've stacked them as long as you apply some common sence and care when storing them.

The car tyre is designed to take a load of anything up to half a tonne in a vertical orientation. You will not adage them storing them vertically, but they are not designed to take weight on the sidewall, so stacking 75-100kg on top of the bottom tyre can damage the sidewall of leave it for any length of time.

But the manual specifically talks about a tyre off the rim, which can't be inflated etc.

Pop down to Kwik-fit and you'll see they are all stored vertically on the racks.

I just lobbed mine upright in an old outhouse type thing (cold but not damp or frosty) in work, the tyre fitter said just don't let them sit in direct sunlight
