Tire pressure in warm tires
Does anyone have a good way to air up tires that are already warmed up?
I don't have a compressor so I have to drive to a gas station to air up my tires. I know doing this warms them up and increases the pressure in them, but I don't know by how much.
I guess I could always go air up to 5 or so psi above recommended then drive home, park overnight and bleed off the excess pressure in the morning. Just looking for an easier way for when I happen to be at a gas station with free air, which is very rare where I live.

That is terrible on tires.. I have had this same problem (after moving) and not having the shop se t-up (three phase compressor not wired) I went to local auto parts store, and bought a five gallon air bottle. I take it by the local gas station / pressure it up to 125 psi and that holds for a least a couple of months riding..
Think the bottle costs around 15-20 dollars.. See ya....

Your gas stations don´t have air/water for free?
I can´t imagine this. Here everyone have air/water for free.
That´s odd

i dont understand that question. sure when a gas in compressed its heats up but were talking a minuscule amount when your only going to around 40psi. or are you saying you have a leak? you shouldnt need to be filling your tires up often. and like 8541hawk said just use a bicycle pump.

Racers deal with this issue all the time. 3-5 lb increase on a hot tire wouldn't be out of line. Maybe you should fill it and after it cools check the drop or check it cold and run it until it's hot and recheck.

Buy an air tank (Walmart, Sears, Autozone, etc) and a good air gauge with a bleed valve. The cheap pressure gauges are good for a rough estimate at best. Unless you have a leak issue, your tires should maintain pressure for a good part of the riding season, but it's still a good idea to check them regularly.

I worked in the tire business for 8 years and I can tell you that 3-5 psi is about right.

that's right>common sense. I've run for an hour fairly hard, got off the bike and checked immediately and saw 4-5 lbs increment.
