The tires I am looking at are the following:

225/45HR17 Continental ContiProContact SSR Blackwall
245/45HR17 Continental ContiProContact SSR Blackwall

1) Do I need to purchase different tires for back and front since it has the "sports" package that comes with different tires in front and back?

2) Can I use the rims that are already on there? or do I need new rims?

Thanks
These are the wheels / original tires:

Double Spoke (Styling 161) light-alloy wheels, 17 x 8.0 front, 17 x 8.5 rear; 225/45R-17 front, 255/40R-17 rear2 run-flat1 performance tires3
So I checked the manual and these tires are ok to use with the car and the specifications seem to call for rims 7-8.5" and 7.5-9" respectively so I will go with the "225/45HR17". Thanks

You dont need new rims.

I dont know these tire models, you need to find out if they are appropraite for your car.

Have you consulted the owners manual?
