Bonjour à tous,

J'aimerais passer en 18'' sur ma m3 e92 (actuellement en 19'') et j'ai trouvé un vendeur qui me propose les 260m que j'apprécie particulièrement, mais en monte Michelin PPS 4S 255/35 ZR18 94Y à l'arrière, et 225/40 ZR18 à l'avant (il a une 335i).

Comment puis-je savoir si les pneus conviennent ? Quelles sont les recommandations de pneus du constructeur pour ces jantes ? J'ai effectué des recherches mais je me perds dans le foisonnement d'informations !

Pourriez-vous m'aiguiller ?

Merci par avance

What are the factory wheel and tire sizes for the E90 M3 sedan, E92 M3 coupe and E93 M3 convertible?

The E90 M3 sedan, E92 M3 coupe and E93 M3 convertible are equipped as standard equipment with a cast M Radial Spoke alloy wheel that measures 8.5 x 18-inches in front (with 245/40ZR18 tires) and 9.5 x 18-nches in the rear (with 265/40ZR18 tires). There are two slightly différent versions of these wheels, identifiable only by a slight deviation in the shape of the spokes: Prior to September 2010, the Style 219M was utilized for the North American market, while the Style 260M was used elsewhere. However, the

Style 260M replaced the Style 219M in North America for the final 2013 model year. Both the Style 219M and Style 260M were painted Ferric Grey prior to September of 2010, at which point the finish changed to silver. 

As an option, the E90 M3 sedan, E92 M3 coupe and E93 M3 convertible could also be upgraded to polished 19-inch forged M Double Spoke alloy wheels (Style 220M) manufactured by Fuchs. The wheel widths are unchanged from the standard 18s and they carry 245/35ZR19 (front) and 265/35ZR19 (rear) tires.
Finally, E90 M3 sedans and E92 M3 coupes equipped with the Competition Package (ZCP) option include cast alloy wheels in a Y-Spoke design (Style 359M). These wheels are 0.5-inches wider (front and rear) but carry the same tire sizes as the forged M Double Spoke wheels (Style 220M).
