Ride Comfort - Going from 18's to 19's

hi guys - I know this question is not as linear as I've titled it but just generally wondering what your experiences are. I'm thinking about going from my stock 18- 40s to 19's -35s. Do you think this switch will make my ride much more harsh? I'm in a big city so i'm always trying to avoid potholes and I want it to be livable/comfortable. Any advice would be welcomed.

Thanks!

depends on the weather

every inch of diameter you go up or down expect a 10% -15% difference in ride firmness

Thanks Luke. As a practical guage, do you think that it will be real noticeable difference in harshness? Put in another way I guess what I'm really asking is, I know I likely will be able to feel the difference, but will my wife be able to tell?!

you will notice a difference but, 19's on an E63 are not bad at all

Hey luke - Just a follow up to this question/response. Does your 10-15% guideline still hold true if you maintain the aspect ratio of the tires. I have 35's on 18's right now and want to stick to 35's on 20's and I will be maintaining the same tire width. Will the firmness factor still increase by your factors or a bit less?

Thanks
