my tyres keep ripping where it comes into contact with the wheel. im making sure that the rim on the tyre(that forms a seal with the rim of the wheel) are touching each other.
do i need to replace the wheels as its pointless to keep changing the tyres as they rip.
what am i doing wrong??

check that you're running on the recommended pressures ( or if you're a bit on the weighty size add another 10% ) - too little air causes the tyre walls to flex beyond their design limits and will lead to splits, also the increased tread contact will slow you down and make you work harder. In addition, soft tyres will become brittle and degrade quicker.
secondly, check the wheel rims are smooth and free from burrs - if they aren't, carefully use some grinding paper to sort them out otherwise it may be time to send them to the recycle bin.
thirdly, are you using a cheap brand or the wrong type of tyre for the intended use ?
although I shudder to say it, speak to the assistants at your local halfords, or better yet, a specialised cycle-shop / builder
enjoy

How long does it take for the tires to rip? Are we talking about days? Weeks?? Months???
As a bike mechanic, my first inclination is that your brakes are misaligned and the pad is touching the tire instead of the rim. The best thing to do would be to look at the offending tire while it is spinning (have a buddy hold that side of the bike up, while you look at the tire straight on) and spin the wheel, look at where the brake pads are in relationship to the rim. Are they closer to the rim, or closer to the tire? Squeeze the brakes while the wheel is spinning as well, and look at where the pad goes. Again, does it run too close to the tire?
Next possibility would be a Pinch Flat, which is where the tire is underinflated and when you hit something hard enough (like a curb or a stone) and the tire pinches the tube between itself and the rim (there is a distinctive 2 hole pattern in the tube similar to the bite of a snake, hence the nickname "Snakebite Puncture"). This CAN actually ruin your tires, but it is more common to ruin the tube or the wheel instead, so I don't think this is your problem. Don't pay too much attention to the posters above, they are referring to mounting CAR tires, rather than BIKE tires.
A couple methods to ensure your tire and tube installation is as good as it can possibly be..
1) Put a couple shakes of baby powder into the tire and spread it around prior to placing the tube inside. This will prevent the tube and tire from sticking together, which can cause sidewall blowouts if the tube gets overinflated.
2) Run your hand around the inside of the rim (strip the tire completely off the rim) and feel for rough areas or burr's inside the rim which might poke through the tire.
3) Do the same as #2, but with the tire itself. Look closely at the bead (the area that seats into the rim) and see if you can see/feel any metal coming through it.
Have you been buying the same brand and model of tire every time you replace it? If so, and you have checked the rim, and it is alright, and the brakes are adjusted properly, then I would suspect your retailer has a faulty batch of tires.
Hope these help!

Whoever is mounting the tires on the rims is not using the proper procecure. The bead of the tire must be lubricated with a special soap before mounting. If the tire doesn't leak around the bead, then it really isn't a problem. It just looks ugly. The mounting should be done on a machine that uses a tool that doesn't rip the bead. If someone mounted the tire with a couple of larger screwdrivers, I would change my tire service company.

check also the wheel alignment

deanryandavis is a moron (see post above)
sounds like cheap tires, too much inflation, or bad rims
get thee to your local bike shop and ask for assistance

Echo other answers. Almost sure to be brake block interference.
You do have brake blocks??
