Upgrading 205/55r16 on e90 sedan
I have a 2010 328i sedan (non-sport pckg) with 205/55r16 tires all around.
I've had the car for about two years and I'm getting close to having to replace the tires. I asked the parts sales rep at BMW San Antonio if I could possibly replace my tires with 225/40 18s (front) and 255/35 18s (back), but he said that there was no way I could do that. He mentioned that that staggered size setup is only for the 335 models with sports suspension, and he told me that I should not attempt to install any other tire size on the car other than the 205/55r 16 because my car does not have the sport package and and tire wider or larger than the current one would rub and cause damage.
I wanted to know if the parts rep is in fact correct...? I was hoping to get a nicer tire/wheel setup to give the car a sportier, more aggressive look (maybe some Breytons). What wheel/tire size can I go up to (if any) without having to use any spacers or make any modifications to the car's suspension.
Thanks in advance guys.
