Pros and cons of fitting BMW 19 inch MV4 wheels over standard 18 inch rims

[Allanz4m]

Hi
I run an E92 and have a spare set of 19 inch MV4s Currently with run flats and was considering the MV4s with new tires on my Z4M roadster
Has anybody don this before ?
Also pros and cons of doing so is the wheel off set being different I understand it is only some 8 to 11 mm difference .

Thanks

I run both 18 and 19. All else equal (e.g. same tires and overall rolling diameter), no real downside imo. Potential cons: tires are more expensive, ride might be slightly harsher, brakes may look tad undersized. Yes 19s weigh more but so do 18” tires. So the weight difference isn’t all that bad, especially if you opt for lighter (e.g. forged) 19s.

Pros - 19s look wayyy better on our cars.

Hi
Thank you for your reply yes I agree the 19s look far better than the standard 18s

To add a slightly different perspective (road driving only, Australia).

I had the standard 224’s on the E86M with recommended tyre sizes (Michelin PS4) and for fun installed a set off 19 inch Style 67’s with Contisport Contact, standard width and roughly the same circumference and the car felt great.

I was then able to acquire a set of BBS RC303 NOS 18x8.5 Square with Michelin PS5 235 on the front and 255 on the rear. 15MM rear spacers.

The BBS weigh 8KG each without tyres and saved a total of 18KG unsprung for all 4 wheels with tyres and I can really feel the weight difference.

I love lightweight because my daily is a 1991 Peugeot 205GTi - 910KG and if I have a 60KG passenger, the drive is ruined.

Cheers,
Sal
