Your suspension will have more bounce, but your tire life and grip reduce while tyre wear and rolling resistance increase. The inverse is true for lower PSI values. A higher PSI value results in a tire having less dampening, low wear, short-term grip and less rolling resistance. Understand How the Tyre WorksĪ tire offers variable grip, shock absorption, rolling resistance and tire wear depending on the tire pressure (and of course, tire compound). Try inflating your tires to a value that allows you to reach the optimal pressure in the given amount of time.
#TIRE PSI CALCULATOR WINDOWS#
Note your tire pressure and compare it to the optimum windows (given below) based on the tire compounds. Start with a baseline pressure value and complete a few laps (minimum 3). Calculating optimal pressure values is easier during practice. In simple terms, the optimal pressure is the tire pressure you need to have when starting a hotlap (in qualifying), or the tire pressures you need to maintain after your formation lap in a race. Getting your PSI number for each tire correctly right down to the decimal values should be your ultimate goal. First and foremost, it is essential to understand the units and measure air pressure in a tire.Īir pressure is measured in Pascal (the SI unit), PSI and bar, but we will stick to PSI as it’s the standard unit used for measuring tire pressures. Tire Pressure is also a very mappable reading in the game.
#TIRE PSI CALCULATOR PROFESSIONAL#
Whether you are an amateur or a professional sim driver, there are many cues displayed throughout ACC to help you understand your car as much as possible. If you thought incorrect steering setups cause unruly cars, inaccurate tire pressures are equally stubborn. If you manage to get the right pressures for your tires during an event/session, you will be able to maximise your car’s performance and make your life much easier.
There are many more nuances, some smaller than others, but they nonetheless contribute to the overall picture. Regarding ACC, the most critical factors that contribute to optimum tire pressures include weather, track temperatures, air temperatures, brake temperatures, type of session and the car itself. So much so, that even a single PSI of pressure above or below the optimum number can cost you 5-6 tenths of a second in lap times. Similarly, an underinflated tire will feel more bouncy and soft but increase tire wear significantly and increase fuel consumption. Long answer, read on! Importance of Correct Tire Pressuresīack to our driving example, we know that an overinflated tire has the tendency to burst, leak some air out and feel super hard in terms of ride comfort. So what is the fuss about tire pressures in ACC and is there a “right pressure window” for each car? Short answer, yes.
#TIRE PSI CALCULATOR DRIVER#
A common question that faces every driver is “Are these tires correct enough to be driveable?”, and that simple question is ever so crucial for racing. Every time you head out of the pits, chances are you’d feel your tires first.
