Tyre pres­sure not only af­fects the per­for­mance and safety of your ve­hi­cle, it can also have a marked af­fect on fuel con­sump­tion. For in­stance, if the tyres are un­der­in­flated, it re­sults in more rolling re­sis­tance with the road sur­face, and more fuel burnt. Of course, han­dling is also com­pro­mised, and driv­ing with un­der-in­flated tyres over pro­longed pe­ri­ods, es­pe­cially at higher speeds, will de­crease tyre life… and pose a se­ri­ous safety risk if a tyre bursts at speed. Over-in­flated tyres, on the other hand, of­fer less con­tact with the road sur­face, and less rolling re­sis­tance, and thus save fuel. But be­cause of the small con­tact patch and a side­wall that doesn’t flex, han­dling is com­pro­mised. So, best en­sure your ve­hi­cle’s tyres are al­ways in­flated to the man­u­fac­turer’s spec­i­fi­ca­tion, or a suit­able al­ter­na­tive (for the con­di­tions).
