First Footage F1 car with 18 inch wheels
![18-inch tyre might be postponed beyond 2021](https://www.f1-fansite.com/wp-content/uploads/2019/09/18-inch-F1-wheels-test-by-Renault-2019-624x385.jpg)
In this footage shared by Pirelli, you can see the Renault RS19 with 18 inch wheels for the first time. Renault and Pirelli are testing toady on Paul Ricard with Sergey Sirotkin.
These wheels and tyres will be used in the 2021 F1 season instead of the 13 inch wheels of today.
Looks great! Doesn't it?

WHAT DO YOU MEAN
What do you mean: WHAT DO YOU MEAN?
Sergey Sirotkin, in a Renault car at Paul Ricard circuit. It is not easy to construct a bigger heap of fail.
As a result of the increased circumference, does this now mean the cars will go a lot faster.
18inch wheels - what will happen is you will get less flexibility when turning bends/chicane and less contact grip, and back end breakaway.
... less contact grip...
Are you sure of that?
Tyre's profiles will be lower. The overall diameter and circumference will stay more or less the same. Unless the tyres' with is reduced the contact grip should remain about the same, no?
The brake disc also can be bigger, so the cars of 2021 will even get better in braking. Because of the lower tyres they cars will react even quicker on steering input and a lot more will be asked of the cars suspension, because the tyres will compensate a lot less on a bumpy track.
What do with a small wheels
Laughing so hard at the thought that people think the tyre overall size will be smaller.
