Tire manufacturers don't know what you are riding. Tire pressure should always be set by the bike manufacturers guidelines. Same with cars. Never use the tire settings.
true, but Yamaha doesn't know what tires you're putting on their bikes. different tires have different qualities and pressure recommendations.
this guy suggests what i did when i switched from the factory Dunlop tires to my current Dunlop Elite 3's - looked up my bike with their tire.
Atleast avon tires ask what model, and year bike your riding and gives you recommendations based on that (or atleast seems to).
Thought I do agree the pressures are a bit high, atleast for my riding style, so mine are set about 2 psi higher than the bike says, but around 4psi lower than avon recommends.
same here. my tire pressures are also just 2 psi higher than what the manual suggests.
and as for getting better performance from tires from different pressures, my bike always feels like it has better traction and handling when i have just filled up the tires versus any other time.
The higher the pressures you use in your tires the less the chance the tire will heat up enough to reach it's optimal temperature and provide adequate traction,
is this correct? pressure and heat are directly related. and the higher the pressure of the gas inside, the quicker the molecules are moving and thus the higher the temperature, isn't it? so doesn't the higher psi give the tire a better chance to warm up? does it even matter that much with a few psi in heating up the outside temperature of the thick rubber? wouldn't the energy of the tire making contact with the road heat it up more than the characteristics of the gas inside? drag vehicles spin out their tires before a race to heat them up to gain better traction. it's been a while since high school science classes and i'm too lazy to research this right now.
edit: i spent a few seconds to find this: Gay-Lussac's Law: The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. As the pressure goes up, the temperature also goes up, and vice-versa.
