    hello

    i have problem with Tire temp , 70° front tire and 40° rear tire in straigth line

    i do separate TGM file for rear/front tire and i dont find in TMG files witch parameter to control Temp (roling temp/sliding temp)

    can someone help me ??

    another problem with tires is when they are dead in RF1 you go to the pit as you can but in rf2 it s seem that you can continu race no different temp between good or dead tire ..
    sorry for my bad english .. a screen perhaps better to understand ..

    i change "AbrasionCurveWLFStartStep=(-106.5,0.5)" in rear tire TMG for to be sure that cant do more then 3 lap and you see rear temp in straight line 160Km/h , and i can steel drive and turn , strange ! !

    You can use materials properties defined at each node. Specific heat and conductivity are at the end of materials line (i think).
    TreadMaterial=( , , , , x , x)

    Roll heating is possible to change using 'DampingHeatEnergy' parameter (Realtime section).

    About the abrasion, i wouldn't change AbrasionCurveWLFStartStep unless you know what you are doing. Just multiply 'AbrasionVolumePerUnitEnergy' numbers to increase or decrease your tyre wear.

    thanks Raintyre ;)

    for each node i have 2 line of "TreadMaterial=( , , , , x , x)" , 2 BulkMaterial=(, , , , x , x) and 4 PlyMaterial=(, , , , x , x) perhaps you know why or what is for ??

    thx lazza

    for the rolling temp now its ok , slinding temp don't understand yet where it is but for the moment i dont change it , abrasion of tire ok ; but now i want to understand why i have "Runflat" tire on the car ..
    i can drive even when the tire are dead

    Copy here your realtime section so we can have a look

    it's from the "Michelin S8B 21-65-18" TGM files from the "rf2tires-0.7.zip"..

    There are some undesired spaces and "lost" characters on the text you posted. I guess it is due to copypasting here, if not those mistakes could cause some trouble.
    Apart from that i don't see any mistake. Last value in Degradationperwear table is 0.865, so grip when tyre is finished is still 86.5% of original. If you apply full thermal degradation i think the result will be 89.2% of 86.5%, that means in the worst of cases your grip will be 77% of initial, which is not bad. I don't know if RF2 makes explode the tyres when they are finished. If they don't explode i think you still have good grip with it.
