    Hello Praful,

    Thanks for the reply. I wanted to ask how we can change the tire profile. The model I have, by default it has the Tire carcass shape for 180_55zr17. I want to change it to 90 90 r10 and the data in the tire file is represented as x and y coordinate in the section named [SECTION_PROFILE_TABLE], how to get that x & y data? Or is it enough if I change the values in the [DIMENSIONS] segment in the .tpf file which has the unloaded radius, width and apect ratio.

    Thanks

    Hello Draucis

    Generally, these tire data is obtained through testing of the tire. They are valid for a particular type of tire and particular conditions as given in the tire file. Ideally, that is what you should do for the tire. It is possible that your tire manufacturer or supplier has this data. You may want to check with them.

    The closest one to your desired size of 90x90R10 that is available in the MotionView install is TNO_mc120_85r10.tir.

    Hi Draucis - Gra is abbreviation for Graphics. The 2 terms represent the tire graphics' outer radius and the width respectively.
