offtopic but
look at that gorgeous machine
Pirelli couldn't do it
Okay, I ment rims
They did that because all tire manufacturers were for it. I also think there were some mechanical reasons.
A further advantage of the wobbly broad sidewalks is that they allow the tyre contact patch to be larger and to conform more to irregularities in the track. It is for this reason that the overall tyre diameter has been increased as well as the rim size. They will struggle to match the current levels of traction on exit kerbs, it may be that drivers will use less kerb because of this.
I hear this theory sometimes, but may I ask for data, articles or studies to back up the idea that a high profile tyre provides a bigger contact patch for a given tyre width & pressure and therefore more traction and/or lateral grip?
If they use less curb, thats just a bonus, im pretty tired of watching the drives drive so much "off track"henry wrote: ↑02 Nov 2019, 13:01

I’m not sure you can compare road going sports cars with the ultimate in track car. There are many factors for a road going car other than outright performance.JordanMugen wrote: ↑04 Nov 2019, 13:28I hear this theory sometimes, but may I ask for data, articles or studies to back up the idea that a high profile tyre provides a bigger contact patch for a given tyre width & pressure and therefore more traction and/or lateral grip?
These are the rear tyres used by the sportscars made by the F1 competitors:Surely knowledgable F1 manufacturers like McLaren, Ferrari, Mercedes, and Honda wouldn't specify a very low 30% profile rear tyre if a higher profile rear tyre would provide more traction for their over powerful sportscars!?
- Ferrari 488: 305/30 ZR20 (20" diameter, 305mm wide, 30% profile)
- McLaren 720S: 305/30 R20
- Mercedes AMG GT R: 325/30 R20
- Honda NSX: 305/30 R20
That's interesting. I think it could just be because the 19" wheels are lighter, while still being large enough to clear the brakes.
