F30 - BMW Recommended Stock Tire Sizes - 328i

[MarcoMeswara]

Guys,Since i got my ride, i have been itching to change the rear tyres to something wider but just could not get any credible info on what are the recommended sizes? Even the BMW website did not have this info readily available. Googling too is vague.Well the door frame sticker came to the rescue. Look at the pics attached.It clearly shows what are the recommended rims and tire sizes.For the 18 inchers , its 225/45 in the front and 255/40 in the rear. Most shops will tell you its 255/35 in the rear..not true for 18s.The rims that come stock with the 328i Sportline are Double Spoke Style 397 - 18" 18x8, whic apparently DONT support 255/40s... So if some of you (gatal like me ) want to change the rear tires to something wider, looks like we need to change the rims as well..Note: This info for newbies. The sifus here may already know this.View attachment 26990View attachment 26991
