What version of Ionic are you using?

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

```auto
<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.
