no spokes are broken. i think it is a tire issue, but i can't see any imperfections.

save your time and money, just take it to the shop.

There are a couple of possibilities here that this could be...
1) Lift the wheel off the ground and try to move it from side to side. If it feels loose, it could be loose bearings, a loose skewer, or a loose axle nut. I suggest a trip to a shop for this.
2) If it LOOKS wobbly because the tire TREAD wanders around then it is either a tire tread molding issue (not dangerous) or the tire isn't seated correctly. Relieve the air pressure and pull up on the tire, working your way all around the rim, then reinflate.
3) If it is neither of the above, your wheel has to be trued and this also requires a trip to the shop. To do a quick check, lift the wheel off of the ground and spin it slowly. Observe the distance between the rim and a brake pad. If this distance remains about the same (within about 1/16") during the entire rotation then it is fine, but could probably be better. Typical factory specs for true is +/- 2mm.

Check to make sure that the tyre is bedded properly all the way around. Especially around the valve. If the tyre has been over inflated it may bulged. if it is a bit old some of the threads in the tyre may have broken.
If you think it is a tyre issue you should take the tyre off and spin the wheel. If the rim runs straight and true, then it is a tyre issue. If not then the rest of these guys have covered it well enough.
If everything is fine then refit your tyre taking special attention to getting it bedded evenly . If it still wobbles replace the tyre.
Just as an additional note. Wheel truing is difficult. It is a skill that can be learnt though. Don't use your best wheel to try and learn. Get a hold of an old wheel and experiment with that. Your best to start from scratch
There is some good tips here (and the appropriate warnings.)

The spokes may not be broken, but they can be slack - they are supposed to be under tension, which keeps the rim centered around the hub. Using your thumb and first finger, lightly pinch each pair of spokes together about 2/3 of the way out from the hub. All the spokes should have a slight give, all about same. If one (or more) set of spokes feels loose, take it to a shop to have them tightened. This will "true" (align) the rim to the hub.

Your spokes have loosened up and the uneven tension is causing the wobble. Truing a wheel is best left to those with experience as it can easily become worse if done incorrectly. Take the wheel to a bike shop for wheel truing.

does the wheel wobble when your not moving? if it does, then it just needs an axle adjustment. any bike shop should be able to do that for free or very cheap (it helps if you buy something from them first, they are more willing to help).
if the axle is tight and the wheel wobbles while riding, then its most likely an out of true rim. a small wobble is easy to fix (for a mechanic) but a larger wobble may demand a new rim. for cheap bikes, its easier and sometimes cheaper to just get a new wheel.

You need to get it "trued". The dudes at the bike shop can help you.

check the hub and/or skewer and make sure it is tight
check proper inflation in the tire and make sure it is "seated"
take it to your local bike shop to check "true"
