How to read this table
Rim and offset uses the European notation: 7Jx17 ET45 is a 7-inch wide, 17-inch diameter wheel with a 45 mm offset. "Versions" is how many approved versions list that size — a rough guide to how common it is. Load / speed is the most frequent service description (for example 91V) among them; your car may require a higher one.
Showing 1,456 of 1,544 approvals: rare special versions are left out to keep the page readable. Records were read from the German-language text and checked against the French text; 99 % matched exactly.
