How big rims without lowering car

Hi!
 
I got a Golf IV 1,6 -02 and I´m planning to buy some new rims/tires for the summer. Do you know how big rims I can have without lowering the car and still not looking like a jeep?
 
I thinking of buying these ( http://www.teletyre.se/index.php?page=shop.product_details&flypage=shop.flypage_falj&product_id=133&category_id=1&option=com_phpshop&Itemid=6 Swedish webPage). Do you think it will look Ok?
 
Thanks,
Emanuel
