Best advice is change to quality tires for minimal improvement, or trade it for a 2016 or later. If it's a FWD model you can get adjustable shocks and struts for it, but they don't make them for AWD models.
Not just tires, but also tire pressure makes a big difference. Keep pressure around 32 PSI for best combination of ride and performance. You start getting over 35 and every small crack become more and more jarring to the ride comfort.
