Oil changes every 3k miles is by far the best single thing you can do. Synthetic not necessary. Regular 5W-20 is fine. Rotate tires every other oil change if possible. Will get the best tire life. There is a maintenance schedule in your owners manual that will point out many other things to have done. The low profile tires are probably cause for bumpy ride. Check the air pressure. They come from the factory with around 50psi and if were not adjusted when delivered the ride will be very hard. 32 is recommended but can go a little lower if it feels like a better ride.
