Like Nissan tried? I think that tyre sizes are mandated depending on whether cars are 4WD (hybrids) or RWD (LMDh or ICE only).

Tyre dimensions are fixed but they have 2 options on front and rear widths.

Front Tread | Rear Tread | Tyre diameter | Wheel diameter | Front wheel | Rear wheel
1-> 310mm | 310mm | 710mm | 18" | 14" | 14"
2-> 290mm | 340mm | 710mm | 18" | 13.5" | 15"

In the technical regulation : https://www.fia.com/regulation/category/118
There is a maximum width and tires dimensions. No minimum.
That's where my reflexion come from.

Thanks for the answers.

The options effectively supplied by Michelin are just
1-> 310mm | 310mm | 710mm | 18" | 14" | 14"
2-> 290mm | 340mm | 710mm | 18" | 13.5" | 15"

1) was designed for AWD, 2) was initially supposed to be the RWD tyre size, but in 2021 only 1) has been used by both Toyota and Glickenhaus. From 2023 the 2) option will be mandatory on new AWD LMH homologations, and it is supposed that Peugeot actually uses the larger rears. LMDh will also use 290|340.

Cadillac has shown the first footage of their LMDh for IMSA and Le Mans in 2023

It is definitely different from their DPi

Maybe this toys can show undertray?

LMP cars had a spec undertray for maybe a decade or more. Nothing complex, two simple tunnels with a flat floor and plank. Lopez' crash in Sebring revealed the current Toyota hypercar hasn't strayed too far from it.

Yes, problem with specs undertrays is best for given regulation, so this is not best example how undertray must looks.

This is why is best to look at cars without constrictions, Pikes peak(IDR), Vlkryie etc..

Are there any news regarding Ferraris hypercar? There should be already a prototype kicking around?

Found an article from February that says that the new hypercar will debut on track at Fiorano this month.

I guess we'll find out soon enough if it's this month. Also why were ByKolles not allowed to take their car racing this year?
