I will admit that I'm not entirely sure what Longitudal is for, but I'd imagine it's to give acceleration/braking some room for error so you dont have to accelerate/brake that exact 47.53% to make full use of the traction. Likewise the moment you turn more than Lateral you will lose traction. Are you turning? If so, by how many degrees? The closer to the Lateral you get when turning, the closer to Max you'll get. But the moment you start changing your direction of movement the game will first take a look at the Lateral & Longitudal values. When moving without accelerating or decelerating or turning only Min is used.

When standing still only the Min is used. This is sort of Rockstar's variant of a Pacejka friction model (google it). You have to look at all 4 of these at the same time to understand how the traction works.Īs Broughy covered the game has a min and max value for the traction where the max is used when cornering. Heres an interesting excerpt from the post that is specific to tires įTractionCurveMin, Max and Lateral / Longitudal.

Others are altered by various game conditions Several of the values are generated in real time in relation to one or more other values, and can have a significant impact on vehicle handling. (holds all info on all cars handlingfiles).īroughy has a good spreadsheet made for quick reference, but not all of these values are constant while the game is running, they are just the base values for each vehicle. He has a few video's about it and you can look up wich cars have 'tiers can clip' in his spreadsheet. Cars with that flag benefit from those, all others don't. The 2 thickest tires are SUV's & Offroadtires. In this case, the thickness of the tires matters.

This means that the wheel can clip through the street upon the rim, allowing for a smoother ride. Tiers only matter when a car has 'tiers can clip' in their handling files. Originally posted by Engineupgrades, Brakes, Turbo, Spoiler & Transmission influence car performance.
