P1/T1=P2/T2 Gay Lussac's law so if P1 is 120psi and T1 is 75F and T2 is 125F P2 is 200 psi In my world, southern Arizona this would not be an impossible swing.

Ron You post the right chart but are interpreting it incorrectly. At sea level atmospheric pressure is ~15psi, and at 7000 ft it's ~11psi. His tire pressure will increase by that same 4 psi. When you measure tire pressure you measure the difference between the pressure inside the tire and the difference outside the tire. A 40 psi taken into the vacuum of outer space would then measure 55psi. 55psi absolute pressure inside the tire. Your potato chips bag bulges but it's still a really low pressure. Probably less than 1psi.

The ambient pressure has dropped, but this does not proportionally increase the tire pressure, it simply adds a few psi to the pressure. It's easy to conduct a thought experiment to verify this. Imagine a tire taken to space (or vacuum environment). The pressure goes up by 14.7psi, which is the original ambient pressure no longer counteracting the pressure from the air in the tires. If the pressure were to be scaled, it would increase by an infinite ratio! --Metin -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

If your tire is going to explode if its pressure increases by 5 psi, you should not deflate it when you go to altitude.

[RBW] Re: Deflate bike tires before ascent in car?
Professional race team support vehicles carry loads of spare wheels, fully inflated ready to ride, up to significant altitudes, often multiple times during the day, with no concern about exploding tires. My guess is these tires are a good deal lighter in construction than a typical touring tire. I've seen that with food beverage containers. Always point them away from yourself when opening to avoid splatters. Even happens on pressurized airplanes. dougP On Friday, August 1, 2014 12:30:27 AM UTC-7, Jim Bronson wrote: The next couple of days I will be driving from my home around 500 ft altitude to over 7000 ft before returning to near sea level.

No, yogurt containers bulge and water bottles do too. They are at 0 psi when they are sealed, so the change in ambient pressure results in a large percentage change.

[RBW] Re: Deflate bike tires before ascent in car?
How do you account for the bulging of *some* yogurt containers and milk cartons low elevations like 600 ft. ?

Re: [RBW] Re: Deflate bike tires before ascent in car?
I have *ridden* from 0 to 7000 feet quite a few times, without doing anything to my tires. So have lots of other people on this list. Our tires didn't explode off the rims. Riding up mountains on one's bike is not a rare occurrence, and tires don't explode when you get to the top. This is not a real problem.

Re: [RBW] Re: Deflate bike tires before ascent in car?
Agreed. You can even take a bike to outer space and its tires won't explode (at least if you keep it at reasonable temperatures). --Metin On Friday, August 1, 2014 6:58:25 PM UTC-7, Anne Paulson wrote: I have *ridden* from 0 to 7000 feet quite a few times, without doing anything to my tires.
