If your LIANA is LXI, SPORT or EMINENT, then make sure the height of your tire is not more than the height of the original tyre!!! With RXi, it is OK.
That means a lower profile on a bigger wheel if you are going over 14" on the rim.
Remember this because different tyre height will cause your ABS system to malfunction and you will experience a change in the braking characterisitic of the vehicle.
Cheers.
