Tyre pressures

Post by the2ems »

Just checking my tyre pressures for the first time. The plate inside the door frame says 2.1 bar all round, with light load. (2 people, no luggage?) That converts to 30.5 PSI, which seems very low to me 🤔

It's fine, and probably more notable because of your previous C3 which most likely had 16" steel wheels. Your new C4 will have 18" alloy wheels and therefore wider tyres have more contact with the road surface and can spread the load more than narrower tyres, therefore they need lower pressures.

Narrower tyres have to have higher pressure to withstand the loads with a smaller area of contact with the road surface.
