Something's going on with the new tire-model when it comes to the FR90. It's just impossible to keep any heat in them At first I thought "Well, this is me in an open-wheeler. You're obviously not pushing hard enough". So I did the same test with both the FR2 and the FRX. And while I'm not about to win any competitions in any of these cars, I can certainly keep the tires warm. What this does to the handling on the leaderboards where temps are always perfect, I don't know. But I have seen people on RD complaining about just that. And there's definitely something wonky. EDIT: Nearly forgot. All three test were done under the same conditions. Practice session, all default set-ups, recording started at the beginning of the 4th flying lap.
