New to Biking--Problem inflating tire
Hello all--
I acquired my first road bike in September last year, and enjoyed riding until the winter set in. Upon returning to school from winter vacation, I have encountered a frustrating problem. When I try to inflate my front tire, it's like there's something obstructing the pump--no air moves through the pump or into the tire (or anywhere else, for that matter). I tried the same pump on a different tube (the back tire), and it works fine. I then tried putting a different tube into the front tire, and it didn't work. I tried inflating both the new tube and the old (front) tube with my mini pump, and I was able to inflate them both, though not up to the pressure that I need. I am baffled (and frustrated). The tubes have presta valves, and the floor pump is one of the Specialized pumps with the head that works for both schrader and presta (supposedly). The weather is so (relatively) warm this weekend, and I wish I could be outside--please help! |
Make sure the valve is all the way open. Try unseating it by pushing it open incase it is stuck.

When you put a new tube in the front what happened that you state it didn't work.

but, The valve definitely seems to be opening--from clamping and unclamping the pump so many times what was a tire-in--need-of-a-little-bit-of-air is now a completely-flat-tire. I can inflate the tire with the mini-pump, which would seem to indicate that the problem is not in the tube itself. The problem seems to be in the way that the pump hose is interacting with the tube valve. |
jimbud--
When I put a new tube in the front tire, I encountered the same problem as before, namely, the pump seems to clamp on to the valve just fine, but when I go to inflate the tire, the pump feels like someone has stuck their finger into the pump hose--I push very hard on the pump, the air pressure indicator rockets to the top of its scale, and no air goes into the tire. |
I may be that the floor pump is not working well.

it may be that the head on the pump is not getting seated on the valve. Push it on firmly. Use your thumb to press the back of the valve through the tire so that the valve doesn't sink into the rim as you push the pump head on.

Thanks for the replies--I've just been worried that I had damaged something in the process of trying to inflate the tire (nothing is too difficult for a newcomer to mess up). |
Hmm. I'd suggest a basic troubleshooting routine.

Thanks to everyone for your responses to this mundane but frustrating problem. I tried it again this evening, and succeeded in inflating the tire. What was the difference? I don't really know. I did mash on the valve a little bit harder than I had been--maybe that made the difference.
Hopefully my next issue will be more interesting. In the meantime, I am excited to ride (once the rain stops). Thanks! |
I have this issue with my Topeak upright pump and Conti tube valve combo (incidental). Two solutions I've discovered,
1) Deflate the tyre a bit before connecting to the pump. 2) Work the pump to around the desired pressure, a gentle tap to the valve connector solves the problem. You'll hear this little "bling" as the valve opens. No idea what the issue is, but it's no big deal using the second method. Works every time but YMMV. |
