I'm assuming (DUH!) that you're not only a newbie HERE, but with bikes themelves. So I'll go easy.

There's no such thing as "quick release tires". Tires are the rubber hoops that go on your WHEELS and get filled with air. You want quick-release-equipped wheels.

So you have what's called a "nutted axle" -- takes a wrench to loosen it up. Depending on the quality of the wheel (nutted usually comes on cheaper bikes), axles can be swapped out as long as the hollow axles come with their own cones. Cones are the 'inner nut' things that the bearings roll against. If the bearings in your wheel's hub are 'caged', which means they are pretty much out in the open when you take the axle out, and held in place with a spidery metal piece (the 'cage'), then you're good for the new axle. I've done this several times for my daughter's bikes. Anyone who knows how to repack wheel bearings can do this.
