How do I take the back tire off of a merax finiss aluminum 21 speed 700c bike?

I tried using pliers however the screw is too tight. I keep getting a flat in the back tire and I don't want to keep wasting money taking it to the bike shop just for them to change the inner tube.

    What you need is a six point 15 mm deep well socket and at least a 3/8 drive ratchet wrench to remove the nuts from the axle.  I'm not trying to insult you. If you don't know the proper tools to use for the job then you probably lack the skills to do the job right.  Figure out why you keep getting flats. However until you obtain better mechanical skills I'd advise you to keep going to the bicycle shop.

    Although the color is different, the bike you pictured seems to be the same as this one on Amazon.com.  https://www.amazon.com/Merax-Finiss-Aluminum-Racin...  The rear wheel is held on with two nuts NOT a quick release skewer.  

    Pliers will NOT do the job.  If memory serves correct, you'll need a 15 mm wrench.  Preferably a boxed end wrench that won't round off the nuts.  1) Have the bike in the lowest gear up front & highest gear in the rear to achieve the most chain slack.  2) Release the brakes by moving that small tab UP.  If needed, also turn the barrel nut adjuster clockwise.  This will give you more slack in the brake cable.  3) If you don't have a bike stand, simply flip the bike over, unscrew those two nuts a little on both sides, gently lift up on the chain & pull out the wheel.  This video may help.

    Use proper Crescent Wrenches, Never Use Pliers (these will usually ruin the nuts).

      The bike shown uses NUTS, not a quick release skewer.
