Fitting Tyres on MTB

[huggybear0]

So I finally got the tyre on the rim although it was tight now I cannot get the tyre to fit on the edge of the rim and when I blow up the Inner tube that has presta valves It just looses air. Has anyone got any tips how to get the edge of the tyre out of the centre of the wheel onto the edge of the rim. The rims are ZTR crest 26 inch. The tyres I am trying to fit are Schwalbe rapid Rob.

The inner tube should push the tyre to the edge of the rim. When you say it loses air is it hissing out? If it is you may have ripped the inner tube with a tyre lever when you put the tyre on.

Hi thanks for your reply. Since I am only using a pump I don’t think it is putting enough pressure in and so it leaks back out of the valve.

Did you open the presta valve before connecting the pump?

You need a better pump, or check its connected properly

Hi yes all open and connected properly thanks.

Sounds like you may have pinched the inner tube when putting the tyre on. In future put it on just using your thumbs going up each side untill they meet at the top

What sort of connection does the track pump have? Does it have a dual connector or single? If a single, it might be for the wider schrader valve, in which case you can get a brass adapter for a few pennies.

Ok thanks. I will take a look. The tyre was extremely tight to go over the rim.

It’ll be tough if the tyre is tight like you say. Use a bit of washing up liqui to help it over.

Hi thanks for your advice it’s a dual so it fits ok. I have 2 hand pumps. I will look at the inner tube when get back home. Like someone said just to check I have not caught it.

Hi everybody

thanks so much for your advice. Guess what I had done?? There was a hole in the inner tube. I fixed the hole and hey presto it’s done.
Thanks so much for replying I really appreciate your help.

happy cycling.
