If you drive at higher speeds constantly, go for a V rated tire.
Why not try the Michelin PLC?Apart from Michelin there is Bridgestone.MY-02, Re88 and Potenza GIII
If you want to upsize the tire you need to decrease the sidewall height.For example go with a 16" rims and a 205/55 R16 tire.
The tires selection would greatly depend on the roads you drive on and the speeds your drive on.
