    Hello

    Can find the size of tire to use with the TBC?

    For example:
    Radius = 0.330
    Width = 0.315
    Rim = (0.217, 750000.0, 7500.0, 3.0)

    What tire size need it?

    What is calculated ?

    Thank you for your response Woodee!

    What I want to know is how to find the right tire size with the value of the TBC for a convertion.


    Thank you for the PDF, I'll watch it.

    Here the value of my TBC:

    FRONT:
    Radius = 0.283 (X2 = 0.566 = diameter of the tire)
    RadiusRPM = 2.01e-6
    Width = 0255
    Rim = (0.210, 750000.0, 7500.0, 3.0)



    REAR:
    Radius = 0.330 (X2 = 0.660 = diameter of the tire)
    Width = 0315
    Rim = (0.217, 750000.0, 7500.0, 3.0)
    325-660-13X13.7


    FRONT: 245-660-13X12 (SizeMultiplier = (1.04,0.85))
    REAR: 325-660-13X13.7 (SizeMultiplier = (0.96,1))

    I always have a problem with the mod physic. I tried several combinations with several different tire from the archive "ISI Tyres".
    The car returns this, many sub-virag. There is a problem on the size of the tire I can not seem to solve.

    So is it possible with only the data of TBC, (No TGM in rF1 mod) to find the right tire size.

    I am learning myself and some of this confuses me.

    TBCs are used with rF1 and the combination of the TBC & TGMs are used in rF2. Currently all I have done is replace the TBCs of an rF1 mod with the TBCs and TGM of an existing ISI/modder mod and it is drivable. It probably isn't physically correct, but it works.

    I suggest you keep an eye on the ISI dev blog as they are going through the dev of a car step by step and they go into a lot of detail! http://isiforums.net/f/entry.php/5-Hello-and-welcome-to-our-new-physics-development-blog

    I reasoned like you.
    I took the file TBC and TGM an ISI mod, but I still felt a problem in physics.

    Maybe the problem is other thing.
    GEN file? GMT wheel? Is it possible ?

    I had actually seen the blog. That's what made me want to convert.

    Could be the difference in dimensions. I believe this is what the multiplier is for. When taking tyres into the tyre tool, all the numbers confuse me, but it does give a visual representation. I think some tyres need recompiling to support new tyre tech. I've not simulated one myself yet though.
