Page 2 - Investigate the mod

First of all we should understand what is happening as the tires wear. Every mod in RFactor can be different depending upon how the creator designed it. We are interested in two things
We only ever need to check that information once for any car.

The the best way to check that for any mod is a little program called CarStat (available on RFactorCentral). In CarStat you select the mod and the car you are driving, and it directly reads the mod files extracting lots of info about the car. It shows weight, power, torque etc, but also what we need - it shows how the tires wear. In GP79 there are only two tires - Michelin and Goodyear - and basically everyone will be working with the same data (it doesn't change significantly by car).

To find this info;
Load the program, and from file choose "Open Vehicle Selector"
Then select the mod, and you car. (e.g. GP79, League Edition, Fittipaldi)
Now look at the "Tirewear 2" tab.

To explain the info, see below the chart from a Fittipaldi. Along the x-axis is the amount of WEAR the tire has left. The y-axis shows how much of the original starting GRIP is available. We can also see how much grip SOFT tires have in relation to HARD tires. As you can see the two tires WEAR in exactly the same style (pattern of the graphs is the same), but SOFT tires will give about 1%more grip than ard tires at any given level of wear.
