Mein Auto: 2016 328xi Touring
I currently have a 2016 328ix AWD with 225/40-19 Fr and 255/35-19 RR tires. I would like to go to a square 245/40-19 and am wondering if the difference in wheel diameter/circumference is allowable by the electronics and wheel well space. If I use 245/35-19 all around it looks like the sidewall will be even thinner than stock and I worry about this on rough paved and gravel roads. Also, the current setup gives me too much understeer. Would the change to 245 square get rid of this, or should I keep the original tires sizes and get front adjustable camber caps and use -2* camber?
Any ideas?
