my bike tires wont pump up. do i have a different valve or something?
i have a folding universal bike, its probably about 15 years old. i tried to pump up the tyres with a normal bike pump, but no air went in. when i screwed the pump on, air came out so i guess the valve works, but i cant force any air in. i have tried different pumps but none work. any ideas?
yes there is a pin in the centre, so why isnt my pump working then if i have the right type?
what doyou valves look like?
are the presta – they will have a little bit of metal sticking out of teh valve which you need to unscrew a bit to allow the air to go in?
are the schraeder – there will be a little pin in teh centre of teh valve which lets air in when pushed down – same as a car tyre?
you do need a diferent adaprtor for each type
additional info……….
if the valve releases air when you push the little pin in then oyur valve is ok.
Check your adaptor on the pump – does it work ok when not on the valve?
Does your pump work ok?
Does your adaptor have the little bit in it that mates with the pin in your valve and pushes is down so that air can get it?
If all the above is ok then i havent a clue and its a problem ive not come accross in my 15 – 20 years of serious riding so good luck sorting it – get it too the shop
