30 inch tires with stock suspension?

Hey guys I have a bone stock 2.2 03 5 speed with 95k miles. I want to put bigger tires and new wheels on, and other people online have said you can go up to 30" with no cutting or a lift kit. So I'm not worried about rubbing but I was wondering if the extra weight would be too much for the 2.2. Have any of you guys put aftermarket wheels and bigger tires on the 2.2 with no big issues? Or is it not worth it? I tried searching the forum and couldn't find any good answers on this.
