F30 - Tyre Sizes

Post by mubzy » 07 Oct 2016, 22:24

Not sure if anyones replaced tyres on the (F30) 320ED version

Current tyre size is 205-60-16.
Looking to purchase 18 inch sport wheels. Firstly the size is likely to be 255-40-18. is this okay to do ?
Secondly, does it look the part ...? or is it a no-match on the ED version ?

Rolling diameter is fine but you've not mentioned what width the new wheels are and what offset.

It's fine to go wider but they still need to fit under the arch and clear the suspension/brakes.

Thanks fr the link Ray but its out of my depth with the amount of technical detail. In terms of tyre sizes they're rear : 255-40-18, and front 225-40-18.
I wouldn't knw offset etc! - Apologies.
DId call the dealership tday, he couldnt find anyting specific on his systems, bt did say it 'should' be okay to do.

The offset is stamped on the wheels - if they're from a BMW dealer, they will tell you. If they don't/can't......find another dealer!!
