How Quickly Do Road Bike Tires Lose Air

Car tires lose air over time when the weather becomes colder every 10 f drop in temperature removes about 2.

How quickly do road bike tires lose air. This is especially important prior to transporting your bike by air. The more you ride the more new tube smell is released into the tube. The inflation rate also rises by the same 2 with every 10 f temperature increase. Thus if we assume the same type of tire materials etc.

The higher the pressure and lower the volume the more quickly the tire will lose pressure. In the us the change between day and night temperatures may be about 20 f so tires lose about 4. Even in the summer months i have to air up my road bike tires every couple days cuz pressure will drop from 110psi to about 90. Even with the same amount of air passing through the rubber the effect is more significant because of the lower volume.

And make sure you have a decent pump with a gauge. Usually drivers get a new set along with the new tires. Mtb tires don t lose air as quickly cuz there s lower pressure involved and air will not drive through the porosity as easily with lower pressure behind it. I wouldn t worry too much about the specific gauge readings but err on the side of more inflation.

If you re talking road bike tires at 100 psi you might be losing a few psi every day so if it s been a few months since you pumped them up yeah they would likely be pretty low. Road bike tires are higher pressure and will lose air more quickly than something like a mountain bike or leisure bike. Over tightening valve cores may also be one of the reasons of the leak. This process is called diffusion.

Valve stems deteriorate and leak air due to the exposure to lots of chemicals on the road. If you can t do this yourself go to a different bike shop than the last one and ask them to do it. And you shouldn t be losing too much air when you hook up the pump gotta be quick. However if a tire loses air slowly yet over 1 3 psi a month they may need replacement earlier.

My fat bike too. It will lose a few psi over the first few days but then it will hold 3 or 4 psi for 6 months of storage. You really need to fill up before every ride. Those of us that spend 24hrs day on our bikes know for a fact that air does not needed to be added to tires though occasionally you do have to bleed off a little of the odor or risk rupture.

On average tires will lose 1 2 psi per day. I have always had to adjust tire pressure before every ride. Road tires lose air more quickly than cross tires and cross tires lose air more quickly than mountain bike tires. Voila lost air pressure in your tires.

My 27 bike may typically lose 1 pound or so in 24 hours and will continue to drop until it gets to the single digit psi range then sit there indefinitely.
