In Europe, the European Tyre and Rim Technical Organisation and the Tire and Rim Association (TRA) are two organisations which influence national tire standards and aim to align national tire and rim standards in Europe. An example would be "E2" - the "E" indicates that the tire conforms to ETRTO standard R75 and the "2" means Estimation of feasible ranges of functional tire characteristics based on tire dimension, inflation pressure, and wheel load Show all authors.

DANGER: Never mount a 17" diameter tire on a 17.5" rim. use the following guidelines based on those in the European Tyre and Rim Technical Organization Standards Manual. For speeds over 160km/h (100 mph), load and inflation must be adjusted according to the table In the absence of specific recommendations by the vehicle manufacturer, use the following guidelines based on those in the European Tyre and Rim Technical Organization Standards Manual For speeds over 160km/h (100 mph), load and inflation must be adjusted according to the table below.

In the absence of specific recommendations by the vehicle manufacturer, use the following guidelines based on those in the European Tyre and Rim Technical Organization Standards Manual. For speeds over 160km/h (100 mph), load and inflation must be adjusted according to the table below. H-Speed Rated Sizes: At each rim diameter, tire widths between 125 and 335 mm and aspect ratios between 30 and 75% are considered. In case of nonexistent tire dimensions a LI of - infty is assigned. Using these data tables the LI of any dimension can be calculated by linear interpolation between the integer dimensions of ETRTO.
