Yeah totally.
That's why the BMW F10 M Sport comes with either 19s or 20s, even though the brakes are the same as on the SE, which comes with 17".

I personally dont like enormous wheels and will be repacing the 19's on my next car with 18's

Do they do a staggered width setup on 18s?

NathanE · 22 May 2011 at 12:44

I have the best of both worlds. 16 on the front, 17 on the rear

It's over 1800kg, so the power:weight is not that great really

God, only 178bhp/ton? How does it cope?

Also the 20's are forged. I dont have to worry so much when hitting potholes (although I obviously avoid most of them).

Probably.
I've decided to do the garden myself, I have 2 weeks off soon so will do the garden and floor the attic in that time. If someone came and offered me £18k-£20k for it then I would most likely let it go. It would be nice to have the money for various things & buy a cheaper car. However, I say that now, but as soon as I sit in the car & turn the key I decide I could never get rid of it

If it's for ride reasons, it's much less noticable on cars fitted with Dynamic Drive.
But I don't think your next car will be an F10 just yet

If you're referring to BMWs, then yes.
It's possible on some 17s, like on my Z3. But it almost always is on 18"+

I reckon there would be less in it than you would like to think.

Purely for bling reasons then I guess as if you aren't using larger brakes then there is no need for wider wheels for softer rubber.

Great .... no practical reason why Vauxhall could not offer forged 19s (other than trying to create a market for bling 20s)

What is this about wider wheels for softer rubber? :confused:

You can run a softer rubber compound on a wider wheel and experience the same wear rate as a more narrow wheel with a harder compound

So if I buy 2x CS3 245/40 for the rear and 2x CS3 225/45 for the front of my BMW, the rear tyres will be of a softer compound?

Yes, 225/40 front and 255/35 rear.

Forged alloy is more about lightness than strength. Yes it's stronger, but that is usually counteracted by there being less of it. That's why it's often used on more adventurous alloy wheel designs. The strength rarely ends up being hugely ahead of normal cast alloys. So yeah, you'll still want to dodge those pot holes.
