Edit: I made mistake, with nodes you do create outer layer of tire, surface that touches ground, so I did edited misinformation to barely readable to avoid confusion which has gotten me more than once with this aspect. But black writing is how things are in real world, still don't know how much of it applies to rF2 but we test, we learn. One thing about nodes that has not been probably mentioned, idea is to model inner liner of tire, all layers are being put on top of that (or more of bottom, but nodes make inner layer of tire). So with those nodes you don't make shoulder of tire, it is just something which you lay up plies and belts, so with thickness of thread you create shoulder of tire and shoulder of tire should in theory have quite bit of say how much steering 'talks' about road, at least that is so with real street tires. So sharp shoulder is something that average drivers consider horrible to drive as it is quite sensitive to road conditions and tells lot about road, average driver considers good to drive to be completely lifeless dead steering and suspension that eliminates every bump so that you don't feel anything about road even from seat, total opposite of what those more active drivers like to have. To what extent this works in rF2, I have no idea at the moment, but I try to test and see if I get any impressions about it.
