The invention concerns a method for diagnosing the inflation condition of each tyre of a vehicle comprising a front pair of right and left tyres and a rear pair of right and left tyres. The main feature of a method according to the invention is that it comprises the following steps: - a first step of determining the actual radius R FL , R FR , R RL and R RR from a comparison of the angular speeds of the wheels, and from an arbitrary equation linking the four actual radii R FL , R FR , R RL , R RR together, in which R FL , R FR , R RL and R RR are respectively the radius of the front left wheel, the radius of the front right wheel, the radius of the rear left wheel and the radius of the rear right wheel; - a second step of determining the relative radius of each of the four wheels from the determination of the actual radii carried out in the previous step and from a maximum actual radius determined during the previous step; and - a step of diagnosing the inflation condition of each of the wheels from the values of the relative radii determined in the previous step.
