For my tracks I have used textures from the various tracks featured in the game and tweaked them if needed (just making sure to credit the original authors) so far no one has been upset with that.
EDIT: Also you can modify the friction and rolling resistance of your surfaces in the .xml file. So in theory you could have your concrete with high grip if you wanted to.Statistics: Posted by Cobb — Wed May 27, 2015 9:52 am
