F1 » Hembery: Pirelli focusing on 19-inch tyres not 18-inch

Pirelli boss Paul Hembery says 19-inch tyres would be preferable for the future, if F1 does opt for change

Asked what his preference would be, if the sport does opt for change, Hembery said Pirelli would prefer 19-inch tyres: “18-inch tyres we have got everywhere and 19 is different,” he replied.

I'm really really confused by this logic.
Surely developing race tyres that CAN be used in more than one series makes more sense?

Nothing Pirelli come up with really makes much sense.

I still see larger wheels as a danger due to having higher weight and momentum should they ever end up coming off the car.
And the additional cost and weight penalty of stronger wheel teathers, suspension... etc.

Surely for cost saving - they should go with the most common tyre/wheel size currently in the world which is about 16 inch - maybe 17.

I kinda of agree with the argument that 13 inch is a bit irrelevant, but likewise, 19 inch is only used on more expensive cars like BMW, bigger Mercs, etc.

But then, this is F1... its meant to be a bit bonkers.

Since WHEN is F1 supposed to be either "relevant", or "diferent"?... F1 is supposed to be, do whatever it takes to lap faster, PERIOD! All this relevant talk is PR crap talk, the world is driving in idiotic SUVs, what does that have to do with F1?...

yah, it's ridiculous to put big rims on those cars. If Pirelli's idea were credible the FIA would allow them to actually compete with at least one other tire manufacturer, like Michelin or Bridgestone, and let the best solution win. Mandating entertainment gimmicks seems to be pretty hotness for the people 'guiding' the rules these days. A shame F1 seems to be turning more and more in to a homogeneous set of interests in a traveling circus like MotoGP. F1 needs diversity, and competition, not doing what you are told and bling bling, treating the audience like a bunch of dumbed down idiots.

Bigger wheels and tires are coming and F1 really can't stop it. Michelin already told F1 they will not come back to F1 until larger tires are implemented. None of the other tire manufacturers are interested in 13" tires since they have no bearing on their road tire technology. Pirelli will not renew with F1 unless bigger tires are part of the series.

So, big tires and wheels....here we come.

And how about that cost cutting active suspension?

Low profile tires save weight as the cast wheel is almost always lighter than the rubber sidewall replaced. The sidewall flex is largely eliminated and replaced by suspension components. this is why high performance sports cars use very low profile tires. Added advantages include more precise suspension tuning, the ability to control compression and rebound rates (sidewall flex is constant), and a significantly increased interior volume inside the wheel to contain braking and energy regenerative systems. 18 or 19 inch does not matter much but the move to low profile tires is long overdue. The possibility of dramatically increasing mechanical grip will possibly allow F1 to dramatically reduce the aero grip and this will be good for racing.
