Complete reworked EUWA Standard ES 3.21 recently released
November 17, 2025
Dear EUWA Visitor,
for many years our ES 3.21 showed how to handle wheels for agricultural tractors from an engineering point of view.
It was historically released to address wheels for agricultural tractors with speed ≥ 50 km/h. Its application, and the high spot marking, has now been formally extended and recommended to all types of agricultural wheels mounted on vehicles with this speed range. The Standard subtitle of the previous version has been identified to name the updated release of ES 3.21, i.e.: “Geometrical uniformity and first harmonic point of agricultural wheels”.
You will find the updated version in our member area for download: EUWA ES-3.21 Geometrical uniformity and first harmonic point of agricultural wheels | EUWA
Best regards
