how to reduce understeer with tire pressure

Sway bars improve a cars handling around turns and corners, reducing oversteer and understeer.

By []. This is a great first step. They will also have a smaller contact patch leading to lower levels of grip and traction, resulting in understeer and reduced steering control. In the more detailed story to come, which our buddy Andrew Wojtezcko from Auto Analyser and Mantella Autosport has graciously offered to help us with, well give you all the theory and background information so that youre not making these adjustments on blind faith, but rather based on a solid understanding of suspension fundamentals. Learning to adapt your driving style to your cars setup is an important skill to develop, but at the same time dont try to drive around big imbalances in its setup. But the former has less max grip so is easier to slide, which makes it "sliding oversteery". Adding pressure will stiffen the sidewall, which typically provides for quicker transitions, better feedback to the driver, and a more predictable break-away characteristic. But I can tell you that lower tire pressure = cushier ride, sloppier handling, reduced MPG, higher tire temperatures and slightly elevated chance of a blowout (directly related to tire temperature) So. How To Reduce or 'Bleed Down' Tire Pressure With The TireTek - YouTube All timestamps on this website are displayed in your local timezone. ","vehicle":{"tags":["technology","safety","tires","videos","how-it-works","evergreen"]}} }); '; In this article, I share an experience where we cured understeer using information from our tyres to guide us and not in the way youd first expect. If your only goal is to improve balance (reduce understeer or oversteer), tire pressures are an incredibly effective way to do it. Rear tire drift is greater than that of the front, and the rear tends to spin out. The vehicle will end up closer to the center of the circle because the rear tire drift changes the direction inward. That left pressures at 23 psi in front, and 16 psi in the rear. Today, I went out and measured my front and rear coil spring diameters: Front = 14mm, Rears = 12.5mm. Additionally, it may be wise to upgrade to performance tires with a wider contact patch and higher quality tire compound to improve the grip of your tires with the road. On the other hand, snap oversteer is a potentially pant-soilingcondition and if youre unaccustomed to even a bit of oversteer it can rob you of the confidence needed to really attack corner entry, in which case youll probably be fastest in a car with a touch of understeer. All-wheel drive is a type of vehicle propulsion that rotates all four wheels with the engines power. Ideal tire pressure is determined by the load the tire carries - higher pressures handle higher loads better. Since you have already changed the geometry with lowering, you just have to experiment with the pressures. This is fun but can get confusing fast. What you want is to be able to pin the throttle and get off down the straight. See my post above. If one of your front or back tires shows a much different wear pattern than its opposite, more likely than not, it's time for a tire alignment.
