Tyres.co.uk offers Citroen C1s from 2014-2021 two options of wheels for Citroen C1s that fit 14-inch wheels: Bridgestone Turanza T005 and Continental EcoContact 6 165/65 R14 79T. C1 Wheel specifications differ, so make sure to double check the registration, placard, dimensions, load index and speed rating before purchasing.
You will find some information about Citroen C1 tyres and the indicated pressures on the placard in the area of the driver's door. On models from 2014 to 2021, it will be on the middle door pillar, while for earlier models it will be on the driver front pillar. The label provides the required tyre specifications, including dimensions, load and speed ratings, as well as the pressure to inflate the tyres.
All four tyres of a Citroen C1 do not need to be replaced simultaneously. Since Citroen C1s (and other front-wheel drive cars) do not require four identical tyres, it is permitted to have four different tyres on the front and different tyres on the rear. If two tyres need to be replaced, UK tyre safety advice states new tyres should go on the rear axle.
