Heights don't follow road car conventions, race tyres are usually labelled by actual tread width (rather than a nominal tyre section width when mounted), and actual diameter/height, rather than a percentage.
So the 670 is the actual diameter of the tyre in mm.

Thanks guys. I was already questioning my own reasoning as the front and rear tires seems to have the same diameter.

But back to the question, does anyone know the thread thickness? Or a good approximation would be nice.

305*670*pi*0.4 = 256 cm^3 front rubber decrease
405*670*pi*0.4 = 340 cm^3 rear rubber decrease

Martin Brundle, Sky F1:

“Somebody I respect a lot in the paddock caught my attention post-race. He said 'there's no point in trying to analyse any race or upgrade, it's simply about who is generating the right tyre temperatures at any given point'. That rather spoiled my day.”


Now I know MB doesn’t command an awful lot of respect on this forum but he does have some super informative contacts. I think he lets on that there’s a major tyre factor in this years performance and perhaps these Pirelli changes are also making Martin sit up and wonder why this has happened.

F1 politics at it again?

Keepin the tyres in the window is a big part of performance this year, they seem far more tricky than last years constructions - it's why you suddenly saw TR shoot up for one circuit and then have been poor since for example, they chanced on a better setup for the tyres than a lot of other teams that weekend.

For sure the difference between being in the window or not is easily half a second.

Maybe not EVERY race, but at lease one ultra or hyper should be fun. Medium-Soft-Ultrasoft or Soft-Supersoft-Hypersoft.

It looks like the SS is becoming the unpopular again. Slightly faster the Soft for the first laps, be degrading and slowing down in to fast.

WTF!

you can't stop stupid.

It's almost like some of said the names were stupid before the season even started...

I like that they're attempting to have more common sense, for being common it's a rare commodity.

Call them hard medium soft, bit keep the colours. So that both newbees and experts can instantly see what tyre it is.

Make the mid range tyre 'standard' then call them 6 then 7 for harder then 8etc.
Instead of a super dupa ultra extra soft it would be a 3. The tyres could still be referred to as a softer or harder where ever they are in the scale.

How in the hell is that a better option?

Supersoft Compound F, Soft Compound E, Medium Compound D

What a joke. It's EXTREMELY simple as it is now. I don't see what about the clear colour differences and titles need rectification.

If you don't know the red Supersoft is softer than the yellow Soft, then you obviously are not a fan and two have a bit of a common sense problem. This shouldnt be on the FIA or Pirelli to cater to

I'm just gonna repost this...

I think numbering would be easier. Dots or bars on the tires indicating compound. One dot: hard. Five dot: soft. Etc.

Or just call them by a performance metric (surface hardness, friction value, etc.) and drop any use of scales or symbols. A "56 tire", a "214", what have you.

What's after sprint? Burst? Jerk? Fidget?

Last year's ultra soft actually had good life, this year it's possibly the worst tire in the range.
