255/40/18 or 255/45/18 ??
I just purchased a new to me 2012 F30 335i Sport with the 19" 401 wheels with Potenza R19 RFTs. I am going to change the wheels out to 18 " Apex EC-7 with either MPSS at 255/40/18 squared or another high performance, summer tire in 255/45/18.
My question is has or does anyone run a 45 series sidewall in 255/18? Will it fit without any trouble? How are the driving dynamics compared to a 40 series sidewall with 255/18? Thanks for your input.
