</ion-tabs>

Answer 1

I am assuming you have 3 pages: tabsAll, tab1Root, tab2Root where tabsAll is the overall and whose code is shown.

You need to send parameters from the tabs to other page. I am assuming the other page is the other tabs? You can make use of rootParams to pass parameters from tabs to other tabs.

tabsAll html

<ion-tabs color="primary">
  <ion-tab [root]="tab1Root" [rootParams]="{rutValue: rut}"></ion-tab>
  <ion-tab [root]="tab2Root" [rootParams]="{rutValue: rut}" ></ion-tab>
</ion-tabs>

tab1Root js

constructor(..., private navParams : NavParams){
  var rut = navParams.get("rutValue");
}

More documentation about rootParams here: https://ionicframework.com/docs/api/components/tabs/Tab/

Let me know if this is what you wanted.
