Every tyre has every important detail inscribed on it .....you only need to squat beside it for a moment. you will find Load Rating, Speed Rating, maximum allowable inflating pressure for that specific tyre, tyre size (this you know), Temperature Resistance Rating, Traction and Treadwear grading. Do not get used to that "thirty fae"..pressure limit depends on the type, besides the size, etc.
