What version of Ionic are you using?

In any case, you might need to put square brackets around checked. E.g.,

<ion-radio value="30" [checked]="true"></ion-radio>

Without the square brackets you are setting the value of checked to the string true, not the boolean value true.

HOpe this helps.

Your model value might be overriding the checked value.
