Equivalence Tires

The "Manual de Reformes de Vehicles" published by the Ministerio de Industria,Turismo y Comercio considers that a tire is equivalent to another when:

  • Load capacity index is equal to or greater than
  • The speed category code is equal to or higher
  • The profile of the rim assembly corresponds to the tire
  • El diàmetre exterior és el mateix, amb una tolerància del ± 3%

Certio ITV ofereix aquest calculador de pneumàtics per determinar la difeèencia de diàmetre de dos pneumàtics i si es troben dins la tolerància esmentada del ± 3%.



  • This utility only provides the equivalence of the tires regarding their outer diameter. Other parameters can be checked with the marking of the tire and eventually the rim.

  • The utility is only applicable for road vehicles belonging to category M, N and O (passenger cars, trucks and their trailers). Mopeds, motorcycles, ATV, agricultural vehicles and special purpouse vehicles are not included.
