I need help, i've been doing some research on this but i'm getting mixed information. I want to install M5 wheels on my 545i but i read that there will be rubbing issues if i install the M5 size tires (Front: 255/40/19 & Rear: 285/35/19). So my question is what tires should i get if were to install these wheels.....by the way i have the Sport Package option. Thanks in advance!

 

the ideal tire sizes are what you'd find on the 2008-2010 550i with 19" 172 wheels.

245/35-19 (Front)

275/30-19 (Rear)

 

the fronts you have to change to 245 35 19, but i kept the same M5 Tires in the rear with 285 35 19 with no rub and Bilstein Coilovers installed. Once i need to replace the rear tires i might go with 275 35 19.

 

Thanks Tourboawd and delje08.....you guys are great!
