wheel question 19 or 20's
 

I currently have 19 in staggered wheels concave on my 07 550i from a 2004 7series. I was thinking about going to 20 inch staggered I found some down the street from my home. Rohana RC26 for $700 no rash with tires. My question is what are the pros and cons or should I just stay with 19's and do I need to do anything to the suspension.

In my opinion, consider staying with the 19's over 20"s. The 19's are susceptible to curb rash and bending the inner portion of the rims as it is. That is if your streets are as rough as they are in my area.
I sometimes wish that I would switch to 18's for ride comfort and lower damage potential.
At this time, I have the M series 19's on a MY 2010 Msport. I am forever preoccupied with defending the wheels
Just an opinion!

Well I live in Jacksonville Florida and the streets are pretty good. But I'm still just thing about it. However these rohana wheels are a steal at $700 plus tires

If your roads are good I'd go with 20's unless they are heavy wheels. That's where most people go wrong with 20's.

My 19's weigh more than the 20's. They are Rohana RC26 concave wheels they guy went down to $600. Needs blk Friday money

Well if you like how they look and they fit along with being lighter then go for it. Make sure they are the right CB, 5x120 and offsets.
