Your new tyre should fit by what you've said. Some tyres can be a very tight fit. Have you got some decent tyre leavers? A bit a washing up liquid on the tyre/rim can help the final part fit onto the rim. hope this helps

its as if when the inner tube isnt pumped up, the tyre wont sit in the rim, but then went i pump it up a bit, its to high to sit in the rim... i cant work it out

Its a 700c wheel and a 700c tyre so it should fit. By what you've said the tyre is too big. Some pics might help.

ive tried taking one with my laptop but its crap quality, its definitely a 700c tyre,

Ive put hew old tyre on top of the new tyre and i mean they are the same size 100 percent...

Altho i dont know if as the old tyre is 622, and new one is 700... if it makes a difference...

622 is ISO and 700 is the metric name, but they are the same size.

Fitting a tyre is something you MUST learn to do yourself other wise what are you going to do if you get a puncture when your out and about.

Inflate the tube just enough to hold its shape as you put it and the tyre on. make sure the tube is sat nicely in the tyre so it doesn't pinch on the rim. as you put the tyre on, press it all into the rim so it sits in there nicely as you put it on. It could be that teh tyre isn't properly on in one or two places so the tube forces it off as you inflate it.

I find skinny road tyres take a bit more attention to seat them in than MTB tyres that realy you just push onto the rims and inflate.

Wide 700c tyres can be a bit of a pain IME.

I do the following:

1. Make sure the rim tape is lying centrally in the rim; if it's off to one side or the other it can get between the bead and the rim
2. Liberally distribute some talcum powder around the inside of the tyre
3. Partially inflate the inner tube
4. Fit one side of the tyre onto the wheel. Align the manufacturer's logo with the valve hole
5. Fit the partially inflated tube into the tyre and wheel
6. Starting opposite the valve, push the other side of the tyre over the rim
7. Inflate the tyre a bit and check round the rim to make sure it's seated
8. Inflate to a high pressure to seat any low spots
9. Let a bit of air out to get to the right pressure
