Hope you don't mind me asking are the 19s an upgrade from 18s ?
I have 18" rims and not sure whether to go to 19" due to the extra weight (extra wear on suspension) and harder ride may be too much for my liking - roads in Spain generally are not smooth. I'd be interested in your opinion
I've been driving hard suspension cars for over 30 years and I'm fully used to it, I prefer it that way, my RCZ has 19" rims.
I don't think that the 19" wheels weigh more than the 18", the aluminium is bigger but there is less tire, since they have to be mounted with a 40 profile and not a 45.
Although using lower profile tires also has disadvantages:
- it is easier to scratch the rim against the curbs.
- there is more risk of breaking the tire in potholes and also deform the rim
