Pumping up tyres?

Joined: 28 Feb 2009 Posts: 8 Bike: | Hi I find it difficult to pump my tyres up sufficiently hard. They do seem to get a bit soft quite quickly too. I dont think it is a puncture because they only go a bit soft and then stay like that. I feel like I can't balance as well when the tyres are not really hard - is that my imagination or is that the way it works? Thanks JEX |

Hope that has been useful!! Live in Sunderland!!!??? Email us: stealthcycling@hotmail.co.uk Thanks! |

MTB? 40-80psi, depending on surface and tyre size if non-skinny road tyres, i'd verge towards the 65 from the 40. there is a very wide range - just like cars etc. some car tyres have 28psi, to a tractor operating on a mere 9psi. most tyres will have max inflation number on the side too. it shouldn't affect balance unless they are really deflated and the tubes wobbling on the rim, which will be really obvious. If it feels wobbly, it is too low, almost definitely. worth checking if your wheels are true as well. lift bike off ground and spin by hand. does the wheel run straight, or have a wobble? best thing is to get a track pump at home if you are planning to cycle alot. quick easy pumping, and a big gauge to see what's what. Can be only £20 hard to get to, and monitor the high pressures with a 'traditional' pump. hard tyres (as long as not too hard) do make life easier with reduced rolling resistance. too low pressure, and your tyres will wear out quickly through too much flex in the side walls. |

I have a road bike, and for the tyres, it is usually a max of 120psi. I tend to punp them up to 100psi and that works fine for the normal commute. On weeks when im also doing distance runs (over 45mins rides) then i usually have to pump them twice per week. It does help if the valves have caps on them (or so i've been told, but i've never noticed any difference). |
