2. TYRE FITMENT
All tyres normally fitted to the vehicle, thus excluding any temporary-use spare unit, shall have the same structure. All of the tyres normally fitted to one axle shall be of the same type. The space in which the wheel revolves shall be such as to allow unrestricted movement when using the maximum permissible size of tyres and rim widths, taking into account the minimum and maximum wheel off-sets, within the minimum and maximum suspension and steering constraints as declared by the vehicle manufacturer. This shall be verified by performing the checks with the largest and the widest tyres, taking into account the applicable dimensional tolerances (i.e. maximum envelope) related to the tyre size designation as specified in the relevant UNECE Regulation. The technical service may agree to an alternative test procedure (e.g. virtual testing) to verify that the requirements of paragraph 2.3 of this Annex are met.
