Checking tire pressure every three months is enough. |
|
False ! A tire can lose pressure, both because its components are porous and because of shocks caused by hitting potholes or sidewalks. You are therefore advised to check tire pressure on a monthly basis, without forgetting the spare wheel. |

Tire pressure has nothing to do with pollution. |
|
False ! Under-inflation has a direct effect on pollution, because an under-inflated tire offers resistance to rolling. This causes additional gasoline consumption and thus more polluting emissions. As an example, a 1 bar shortage of pressure increases gasoline consumption by 6% (source : Michelin). |
