An experimental tire model based entirely on the theories of one individual’s studies is bound to cause problems, and this has been a source of continuous frustration for long-time iRacing members. Dubbed the New Tire Model project, and first launching in September of 2011, Papyrus legend David Kaemmer has embarked on a mystical journey into the depths of sim racing hell, focused solely on developing his own theoretical interpretation of tire behavior within a modern racing simulator. However, his efforts have unfortunately gone largely to waste – the perpetual science project of one man’s research into how rubber behaves under stress has warranted six builds and countless revisions that have all failed to truly nail racing slick behavior found in older simulator engines. While the game aspect of iRacing has always been leaps and bounds ahead of the competition, those who want an unprecedented driving experience are usually forced to look elsewhere due to a tire that’s never felt quite right, and in some cases, extremely wrong.
And there’s a reason for that.
He’s not much of a PRC.net reader, but Jake C. has sent us in a hilarious iRacing.com forum capture, indicating the mastermind behind several Papyrus simulators appears to have lost his way. And sadly, even when Kaemmer is 100%, unquestionably wrong in his theories, those who have sunk several hundred dollars into the service still bend over backwards to defend him at all costs in a glorious display of Stockholm Syndrome.
I’m not a reader of PRC.net necessarily, but I do get a laugh out of some of the things posted. I’ve always hated iRacing. It’s an immersive game, and that immersion tricks people into thinking it’s realistic. It wouldn’t be so bad, but the guys there throw money at their rights and have no idea what acceptible Force Feedback feels like, and shit talk all other sims as if they were arcade games with such vehemence. I’m sharing this with you because it’s bullshit. And not many people have the balls to say anything in public about iRacing. Hell, a lot of the pro drivers fucking hate iRacing’s physics, but they shut up and put up with it because it’s not like rFactor offers $10,000 officially licensed championships.
Anyways, some guy on the iRacing forums had a problem with negative camber setups producing outside shoulder tire temperatures that were much too high. I mean, the tires literally weren’t cooling down at all, even though they were being blasted with air and physically not touching the ground.
David Kaemmer, the man himself, comes along to say that the outside of the tire shouldn’t be cooling down.
This is totally false. In fact, another user in the thread posted a video of Paul Di Resta running laps with a thermal camera attached to the car, which shows that tire tread not in contact with the road will cool down faster than tire tread that is touching the ground. But of course, iRacers are coming up with all kinds of bullshit to support iRacing and David Kaemmer.
Now obviously in the first few seconds, you can see the tire blankets come off and the temperature doesn’t change much. But as soon as he starts driving, they begin cooling down. Yet according to David Kaemmer, airflow making contact with the tires doesn’t cool them down at all! I just don’t get how people can even form an argument against the Di Resta video. But the brainwashed iRacers certainly tried anyways. And typically, they make anyone who speaks out against the glorious iRacing overlords to be outcasts and conspiracy theorists. As if they are saying they were abducted and anally probed by a pack of aliens.
Away from the iRacing forums, where you’re instructed to bow down to Lord Kaemmer, this is even being laughed at on Reddit – which is usually full of iRacing apologists. A portion of a tire that isn’t touching the ground isn’t subjected to friction, but is subjected to air cooling. Convection happens as the temp is essentially chased from the outside of the tire to the inside where it remains touching the ground. Now it’s okay to prefer one thing over someone else based on opinion, but it’s another to say that you value realism and factual data over everything else but then warp your version of reality when something factual doesn’t fit the narrative of iRacing.
This isn’t surprising. David Kaemmer thinks a NASCAR tire should never reach over 220 degrees without losing grip, yet they are constantly hovering around the 280-300 degree mark in real life. He’s also got no idea how centrifugal force works on a tire at speed, but that’s a story for another time.
So as usual, the fanboys just assume Kaemmer is correct, and find any way they can to defend his findings. The scary part is, half the people in the physics forum say how amazing and brilliant Dave is for knowing stuff even real race teams don’t, but for whatever reason, this knowledge is never translated into a competent tire model after how many builds now? iRacing’s got seven different tire models with this allegedly cutting-edge information from our collective Lord and Savior, yet all seven of them drive in a completely different fashion and give extremely different telemetry readouts.
The best question to ask, is how many other little errors have been made within iRacing’s current rendition of their perpetual tire model project, if mistakes this blatant are deemed acceptable.
- Guy says the outer edge of his tires, which aren’t touching the track, aren’t cooling down.
- David Kaemmer says tires don’t cool down even if they’re not touching the track.
- An F1 thermal imaging video is posted to prove that portions of the tires not touching the track do indeed cool down, proving Kaemmer wrong.
- Fanboys bully the OP and claim Kaemmer is right anyways.
What is New Tire Model V9 going to look like? What about Version 11? What other shit is going to pop up for iRacers to discover?
