Place the strawberries inside your blender. Pour the tequila over the strawberries. At this point, you can refrigerate the strawberry mixture for 1 hour or just continue.
Blend the strawberries and tequila until pureed.
Stir in the lemon lime soda, beer, limeade concentrate, and ice; pulse until thoroughly combined. Transfer the mixture to a large pitcher.
Rim margarita glasses with salt, pour in the drink and garnish with lime slices. Serve.
Notes
If your blender isn't big enough, you can blend the strawberries and tequila in it, transfer them to a pitcher, and stir in the rest of the ingredients.
