cold tire temp is the temp on tires that haven't been warmed up on any given day by riding on them

don't worry about ambient temperature

when tires are warmed up, they increase pressure by 4-6psi

You cannot ignore ambient temperature because tyre pressure varies with it. A 17C difference in ambient temperature gives a 2psi (approx) diff in pre-warmup pressure. Probably splitting hairs if you are content to be 2psi out on your running pressure.

cold being around 15-20 degrees. Thats cold enough from optimum operating temp of 60-70 degrees!

Matt

you are studying chemistry?

I studied applied heat. 15-20C approximates to 60-70F, the rest is what? Are you saying that tyres get up to 70C? If so I am amazed.

yes, IGNORE ambient temperture

what ever temperature it is when you start to ride, check your pressure before you ride, if the pressure doesn't meet recommended cold pressure, raise or lower it accordingly, regardless of temperature

what temp is a warm tyre? :o)
 

Does anyone know what temp a tyre achieves when it is warmed up? Is it fairly constant?

Re: what temp is a warm tyre? :o)
 

40°F-60°F above ambient temperature,
