Not sure which post to reply to so I've picked this one.
Yes, I'm 100% sure. The Ideal Gas Law states that the pressure of a fixed amount and volume of gas increases in direct proportion to absolute temperature. (Mass is not in the equation)
PV = nRT
P = pressure
V = volume
n = no. of moles (molecules) of gas
R = gas constant
T = temperature (absolute)
The assumption is that the gas shows ideal behaviour. At typical tyre pressures and temperatures, the deviations for oxygen and nitrogen are minor and can be ignored.
This of course is only true for dry air, and air from service station compressors is likely to contain some moisture. That's one good reason for using nitrogen, and there are others. We got a free fill of nitrogen in the new tyres on my wife's car a year ago, and they have only lost a couple of psi in that time. But I'm lucky if the back tyre on my motorbike lasts 6 months.![]()
Your logic is based on theory, mine and others on here are based on fact and history of working with tires in a serious racing environment.
The back tire of your bike would last a lot longer if the chain tension was set correctly, and the shock/suspension sag settings were done correctly also, and also if the tire was at the reccomended PSI of the manufacturer of the tire, and NOT at reccomended PSI for the bike, with the tires it originally came out with!
You need to re read some of the other replies on here, which are full of facts, and not neraly facts then dude, as your original comment is incorrect, but I did not have the data to show you so. I just know 100% that your original comment was incorrect, due to my history with racing world, and asking questions and paying attn to the top people in the motorcycle racing game.
We can all learn a new thing every day, but sadly just some thing use full every six months or so un-fortunately![]()
What I've posted is a scientific fact. It doesn't matter whether or not you consider it correct, it simply is. End of story.
My rear tyre would last longer if I used less throttle!
O well as said, we live and learn. I wonder why the factory teams with millions of dollars to spend do not always use it then, that has got me beat. Cheers for your input, but I will sticking to the formula that I and many others have worked for years, as it is a proven one to me/us.
I have highlighted a portion of your post you haven't considered relevant. I do note this thread isn't meant to be an argument thread.
while what you are showing is the gas laws you are not considering the effects of the different molecular status of the different gasses
These attributes are forever tied together. They are highly relevant to there mass and other physical properties.
Kb is pretty lucky as they have a world renowned physicist who posts, I would ask him the question on the ese thread. I am sure he would welcome a non Ryger question.
