In fact, it’s a bit like trying to predict the weather – you can make educated guesses, but there’s always a degree of uncertainty involved.
How Temperature Affects Tire Pressure
So, how does temperature impact tire pressure? The answer lies in the science of gases. You see, the molecules in air are in constant motion, and as temperature increases, they move faster and faster. This increased motion causes the air molecules to expand, which in turn increases the pressure inside the tire. Conversely, as temperature decreases, the molecules slow down and the air inside the tire contracts, reducing the pressure.
But here’s the thing: the relationship between temperature and tire pressure is not linear. It’s more like a curve, with different rates of change at different temperatures. To give you a better idea, let’s look at some data:
