With P2 set to be kicked out from the WEC, ELMS might see a further increase of those entries. Combined with the GT class swapping the GTE platform for GT3, there'll be an abundance of entry requests in ELMS as well. The response might very well be to eliminate P3s from the series. |

Since the concern here is tire warmers, seem to me the only difference between AOC and IMSA are tire MFG and drivers in some cases. Will be interesting to see what happens when LMH and LMDh cars run at IMSA together. |

What we have here is the internet and the difference between “the same tire” and “the same tire manufacturer”.

Same tires used in all GTP classes but there are two compounds allowed based on track conditions and tire allocations are different depending on the race. Here's the tire specs:
https://www.imsa.com/wp-content/uplo...ations_GTP.pdf Here's the chart with all of the classes for the 24 Hours of Daytona. Page 4 indicates the tire compounds used. https://www.imsa.com/wp-content/uplo...24H-011823.pdf As you can see there were two compounds that were allowed for each prototype class. GTD and GTD Pro could only use one compound. All were Michelin branded tires. No tire warmers allowed at any IMSA events. |

I'd call Jackson motorsports if in the states. Not sure on non imsa pricing, but they're the race tire distributor and tire logistics people for imsa, along with a host of other non dot products. Also dot products. Also marketing and events if you're in to that sort of thing. More than just tires at any rate.

So where to the need for tire warmers factor in here? Is it that Michelin makes better tires or is it that drivers in IMSA know what they have to deal with and suck it up and deal with it?

One also has to remember that the types of surfaces that are raced on in North America are different than in Europe. Places like Sebring and Belle Isle are a concrete type were as Indy, Road America, and even COTA are asphalt/macadam surfaces. Very few tracks in Europe have a majority concrete surface, be they road courses or street tracks.
It is this that Michelin has to design tires that work on multiple surfaces for IMSA, whereas FIA are a more consistent surface. |

So easier! (WEC has Sebring and Le Mans adds a little variety)

Not buying all of this track surface BS. The Petit is on a mostly asphalt surface. Tires are not the issue here. Drivers need to get weaned off of tire warmers and get with program. Learn to be professional drivers. |

Also it has to be remembered that until this year (?), Michelin did have a virtual monopoly on LMP1, and on LMH's early 2021-22 incarnation. However, even back then (early LMH), and certainly in LMP1, each team had confidential tires to a degree. Even with the "spec" tires in LMH, the tires were made in two specs, hybrid and non-hybrid. Now, there's basically one spec, and that seems to favor the hybrid equipped LMH/LMDH cars.
One thing that I think has helped Toyota cope to a large degree is that they've been doing this for year, and the drivers that have come from IMSA or have a lot of IMSA experience have also adapted better. I think that most of Ferrari's drivers were taken from their pool of GTE/GT3 GT drivers, series that I believe previous used a form of tire warming. However, I don't buy the tire warming deal entirely. If they did like how they did it back about 15 years ago (put the tires into ovens that ran to 150-160 degrees F), if it was cold especially, in the time it took to get the tires from the oven, to the pit area to the being bolted to the car, I'd suspect that the tires may've cooled significantly. We didn't really see these issues, at least big time, at Sebring or Algarve because of the weather as far as ambient temp (and hence track temp ranges) were fairly easy to guess. Spa, with the traditional spring Ardennes weather, is a crap shoot. It even snowed at Spa at least once in recent years. So one can maybe forgive Michelin and Goodyear, even if they were going conservative, for getting it wrong. Granted, Le Mans is a bit of a crap shoot. Though most races in recent years were in the 70's during the day, there were years like in 2000 and 2005 where it was in the 90's with temps in the front engine GT cars getting as high as 150-160 degrees at times, and every time it rains it tends to drop into the 60s max during the day. |

Mikkel Jensen:
"“The tire used [in GTP] is the soft-high temperature. They are not using the medium-high temperature which [in Hypercar] we are obliged to do a double stint on because of the tire allocation. “We have to use MHT. It takes away a minute or half a minute in Spa conditions, but it’s just the best tire for a double stint. So we have to use it, and that’s when it gets super risky on the warmup." https://sportscar365.com/lemans/wec/...s-for-le-mans/ |

For IMSA, they have been using the softer options (low or high) from Michelin in GTP thus far, but starting at next race the MHT will be the only one on offer.
https://www.imsa.com/wp-content/uplo...TP-REVISED.pdf Later in the season they have left the door open to choose tires depending on what they find in the first couple of races on the MHT |

Not sure if this is the best place to post this. If not then please could it be moved by a mod to the correct place so that as many fans as possible can fill it out.
WEC/ACO have launched an official fan survey similar to the F1 one so that YOU can share your views on the championship. Not sure if they will act on anything that the fans want but it cant hurt to fill it out. https://fiawec-global-fan-survey-202...rtnetwork.com/ |
