New to the group and searched the Forum and found similar but did not find this specific question answered so forgive me if you all have been over this.

I have 2003 MCS with 17 S-Lites w/ Dunlop SP Sport 9000 and find the ride extremely harsh for New York City and the BQE not to mention I've driven less than 600 miles before I had to replace a tire due to sidewall damage. I love the the car and the ride I would just like to ease off a bit and now it's stiffer than my sisters M3.

My question has a few parts.

1) Will switching to 16" wheels and tires make a significant difference?

2) Will switching to non run flat tires make a difference or will I be in greater danger of damaging a wheel?

3) Will switching to 16" wheels and non run flats make the biggest difference.

4) Will 205/55/16 rub? I have read both yes and no.

Any thoughts from people that have been through this specific drill?

Thanks in advance.

 

1 Yes - smoother ride

2 Same as above, and less likley to damage a wheel - more compliant sidewalls

3 yes

4 yes when the suspension travels.better on non lowered apps.

thanks Alex,

do you know the diameter size difference between 195/55/16 and 205/55/16?

Also I read somewhere that the RF sidewall helps protect the rim because it is thicker/stiffer and absorbs more of an impact. This is false?
