I'm usually pretty good about checking my tire pressure for both the bike and the truck, but I guess I'd forgotten to do it for a little while.  Very surprised to find when I checked today I'd been riding around with about 20 psi in front and 25 psi in the rear.  I think a big part of that is that we had our first frost here and the temps have generally been much cooler this past week, tire pressure goes down with the temps.  Just a reminder, if you haven't checked them for a few weeks, do it now, or as soon as you have time.

My front tire loses 5 psi a day and gets checked regularly. But the rear hasn't been looked at for a while.....My bike must be a male..I never ignore a female rear

I checked my other steed the other day, wow, about 17 PSI low! Good call on the tire check, like changing batteries in smoke detectors, so simple.

Tires are even easier to overlook when you cant get a pump down there to air it up. Some how mine are near right but I still want to get some air in the rear. I have a metal valve stem so it's a trick on the 16 inch rim.

The last time that I replaced the rear valve stem, I had them put in a "shorty". What a difference in checking/filling.

A shorty would be nice but after half ripping off a rubber one I knew I couldn't trust it anymore. Next time I need a new tire I will get an angled metal stem.

Hobbit,



If you are loosing that much air per day you need to get either the valve stem or the tire fixed.

In a mechanically sound tyre with no rim issues, one would expect a pressure fluctuation weekly of between 1/2 to 1 1/2 psi. what can further aggravate this is contained water within the air chamber so if you use a compressor to fill your tyres, fit an inline filter to reduce moisture content in the deliverey line and regularly drain the blow off valve underneath the compressor
