Rubbing with 275/30 20" Tyres on a non-xDrive car?

I currently have 265/30 on the rears and have no issues at all. I want a bit more sidewall and contact on the road so am looking into 275/30.

Anybody used this size and can confirm there are no issues with rubbing, even when the boots loaded up or you're carrying a few people?

Obviously this is for an aftermarket set of wheels, so people with stock sizes, don't worry about it!

My car has 265 rears on 403M with 12mm spacers; Ohlins Road & Track all round (substantially lower than stock) - no rubbing.

Unless you are aggressive with the offsets for the aftermarket rims I think 275 will be OK.

What's the offset on your wheels?? From what you said I should be fine with 275 but as you mentioned offset couldn't be the difference.

Thanks for the response btw!

I don't know what the ET is for the 403M rears - Google can help Then you'd have to adjust by a further 12mm for my rear spacers.

Tyre selection is also a factor. I noticed that the MP4S has a more bulging sidewall than the MPSS that I was running previously (they had a more square section tread/sidewall).
