Hi Abhishek 
Are yu using the sample code available in 

Basically in SLDS by deafult Tabs are not in working condition because they dont have any scripting done, it is just UI framework.
You have to utilize nested component architect and component level event framework to make Tabs working.

1. Create component TabComponent
<aura:component >
<aura:attribute name="index" default="" required="true" type="Integer" description="the tabIndex for Tabs created" />
<aura:attribute name="stateClass" type="String" default="" description="class derived from the state for the tab" />
<aura:attribute name="active" default="false" required="true" type="Boolean" description="one of active, blank(in active)" />
<aura:attribute name="label" default="" required="true" type="String" description="what the user sees as Tab name" />

<aura:handler name="change" value="{!}" action="{!c.doUpdate}"/>
<aura:registerEvent name="settingSelectedTab" type="c:SettingSelectedTab"/>

<li class="{!v.stateClass}" role="presentation" id="{!'innertab' + v.index}">
        <a class="slds-tabs--default__link" onclick="{!c.fireEvent}" href" role="tab"
           tabindex="{!v.tabindex}" aria-selected="{!v.ariaselected}" >{!v.label}</a>

    doInit : function(cmp, event, helper) {
        var current = cmp.get("");
        //setting the default tab as ACTIVe tab.
        cmp.set("", currentlink);
            cmp.set("v.stateClass", "slds-tabs--default__item  slds-text-heading--label slds-active"); 
            cmp.set("v.stateClass", "slds-tabs--default__item slds-text-heading--label");
    //Function used on onClick of tab links.
    fireEvent : function(cmp, event, helper) {
        helper.fireEventHelper(cmp,  cmp.get("v.index"));
    //Function used for updating the style of selected tab as ACTIVE.
    doUpdate : function(cmp, event, helper) {
    //Calculates the style of Tabs and sets the ACTIVE tab as highlighted in red color.
    calcStyle : function(cmp) {
        var active = cmp.get("");
        var styles = "slds-tabs--default__item slds-text-heading--label";
        if (active) {
            styles += " slds-active";
        cmp.set("v.stateClass", styles);
    //Fires the Component level event to set the Tab as Active.
    fireEventHelper : function(cmp, indexNum){
        var cmpEvent = cmp.getEvent("SettingSelectedTab");
            "activeTab": indexNum

2. Component level event - SettingSelectedTab:
<aura:event type="COMPONENT">
	<aura:attribute name="activeTab" type="Integer"/>

3. Finally create component which contains the Tabs: TabContainer.cmp
    <aura:handler name="tabevent" event="c:SettingSelectedTab" action="{!c.handleSettingSelectedTab}" />

    <div class="slds-grid slds-wrap slds-grid--pull-padded">
        <div class="slds-col--padded slds-size--1-of-1 slds-m-bottom--large">
            <div class="slds-tabs--default">
                <ul class="slds-tabs--default__nav" role="tablist" aura:id="list">
                    <aura:iteration items="{!v.accList}" var="acc" indexVar="index">
                        <c:TabComponent label="{!}" active="false" index='{!index}' />

handleSettingSelectedTab: function(component, event, helper) {
        var cmpnentChildList = component.find("list").find({
                instancesOf: "c:TabComponent"
            //finding the child components and setting the active status
        for (var i = 0; i < cmpnentChildList.length; i++) {
            var outputCmpArr = cmpnentChildList[i];
            outputCmpArr.set("", outputCmpArr.get("v.index") == event.getParam("activeTab"));

Let me know if any issues.
