I have the 2013 sport limited with 17" wheels. I have a question regarding the suspension. Most roads in NY/NJ are horrible. After driving the new car for 12000 miles. I found the ride is very harsh, I can feel every single unevenness of the road. I know it's not the tires or wheel not balanced. because the car is smooth at newly paved road. But once I get into the regular roads. I feel can feel everything and a lot of body rolls when passes by a bumper or such. I also tried to have the tires at prefect pressure, that didn't help much. Does that have to do with the suspension? or have to do with the skinny tires. Should I bring it to the dealer for a check?
