Yeah I'm trying to see if it's worth it to go 225/35 because of the extra rubber. The only thing is that with 225/35/19 my car will lose some of the gap that I have now because the diameter of the tire is 0.12" more than the 225/40/18.
With 215/35/19 my car will have less gap because the diameter of the tire is 0.16" less than the 225/40/18 but ride quality would be sacrificed.
