That is the standard fitment for 20s. You should be fine.

You are correct. I state the standard for 19s.

Decreasing the gap is to usually to give the car a more sporting look, fitting a bigger sidewall tyre does the opposite aesthetically, and it raises the entire car up higher, throws the speedo out and increases the rolling radius making the car slightly slower. |

if you add 15mm in the back and 10mm up front they take the wheel out a bit and aesthetically it will enhance the look of the car, including the gap. |

I fitted 20mm rear and the 15mm up front at first but didn't like the change in steering and the rear wheels were a touch too far out for me. 15mm on the rear brings the wheel out enough to decrease that massive gap without looking aftermarket. The fronts could support 10mm and also not look OTT, but I have never liked spacers on the front due to what it does to the steering, and this car was no exception. It does enhance the overall look to bring the wheels out a bit, but I wouldn't say it makes the gap look any less. on 20/15, it actually made the gap more noticeable IMHO, although maybe thats just because I was looking perhaps. I'm not lowering while the car is so new and the M Sport gap isn't overly 'offensive' on OEM wheels IMO. Usually changing wheels is what makes me think "it needs lowering". |

Thanks Guys! Im hoping to make a decision soon with all your feedback. Spacers sound almost like increasing the tire size since this changes steering or suspension no mater what I do

You can go for the one size up in width (255/35 and 285/30). It also better fills the wheel arches since there's a direct relation between width and sidewall height of your tires. Best is to remain in the 3% diameter variance: Cheers

I cant stand the way the stock tires look, they look like rubber bands to me as well. I need a little more rubber on there and i'm not sure what the best choice of tire sizing would be. Any additional info you have would be greatly appreciated. Thanks! |

People in this thread are so worried about rolling diameter etc..those days are over. I have to ask how old they are. You have people doing Liberty Walk kits and Air Ride.
My speedometer reads exactly the same as Waze because it's all digital. This isn't the 90s anymore. |

Aren't the speedos getting their info from the abs sensors so rolling radius must be key to it ( with a little margin for error to allow for tyre wear)
Does the tyre settings in idrive then influence the speedo in that case? |

Thanks for posting the pic and you have answered my question mate I am getting 669M allloys and wanted to fit tyres same size as yours because 20" OEM G30 tyres are 35/30 profile which look not much tyres and I need more types so not hard on the back . I know I could get 19" but bigger the better |
