I dont understand why you talk about the Sauber and The STR :?:
The STR maybe was good aerodynamically but very weak mechanically...

The width of the car is unchanged in the 2014 regulations. Hence wider rear tyres can only grow inwards.

You can get some indications that the power delivery will be very different, the top speed will be different, the aero loads will be dramatically different. There’s a big question on the correct tyre sizes for next year, you’ll have less aero downforce, so maybe you need wider tyres to create grip. There’s a risk of having excessive wheelspin.

“So there’s a lot of parameters there that would create quite a lot of concern, so you’d have to take from my point of a view a very conservative approach, so we’ll be back to no pit stops or one if you need to, and talk about other things.
That is the message from Pirelli. I'd say that wider. Rears are quite likely, but contractual issues are still holding up the tyre supply and design work. A very messy situation.

Precisely WB. But is anything confirmed about a change in tire sizes??

because the last year toro rosso had a very aggressive sidepod and this was their problem(according to my sourcers). they were just examples that narrow sidepods dont work. it could be that next year they could give some benefits who knows i just gave my opionon and explained the reasons of that.

I edited the post to add some info on that point. The answer is no. Pirelli is waiting for contract confirmation.

But on second thought the FiA could actually change the regulations accordingly. We do not know anything to be honest.

Okay. I just didnt see how it's related to the post in which I was mainly talking about the fuel tank height and the sidepod length, not the width.. :wink: In addition, The C32 has heavily overcut sidepods while the STR6 and 7 had heavily undercut sidepods...

Back when the tires had grooves the rears was wider than the fronts. But when they went back to slicks the rears was made same size as the fronts (i.e. narrower). This was because a wider rear tire would gain more grip percentage wise than the fronts. And to not upset balance the rears was made narrower.

If the new engines need wider rear tires wouldn't it be better to make the tires wider at the front as well?? To maintain the grip balance between front and rear? This could also give some more mechanical grip now we are loosing so much downforce next year. But I guess that's what Paul Hembery is saying.

Uh... . As far as I know the fronts were made narrower:

I quite like the new width on the front wing, a little bit less of the snow-plough effect.
Indeed. My hope is that there are fewer incidents next year in which endplates wind up strewn all over the circuit because of contact. We didn't see nearly as much of that with the narrower wings of the pre-2009 formula.

(Nice gif, by the way.)

Yes of course sorry. They were made even narrower as it was the front tires who gained more grip percentage wise from removing the grooves as the grooves made up more surface area on the narrower fronts than the rears.

My mistake.

But I still think the front tires should be made wider next year if the rears are made wider.

No problem; it still didn't defied your point. Just a detail I had to correct :P. Though it gets complicated when we add in the loss of rear DF. They will be loosing a big chunk of rear grip next year, upsetting the overal balance. Increasing front tyre grip might not be a good solution after all.

I don't think you can compare aero and mechanical grip like that. If you have wider rear tires next year and the fronts stay the same you would have more rear end grip in slow corners than today. I know there will be a lot less rear DF next year. But you'll have to decrease the front DF as well to balance this out. So there will also be a lot less front DF next year.

Lol. About the CGI image Ferrari published and where we see the turbo placed on top of the engine; I just recalled that Ferrari often did that in the past and instead of placing the turbo(s) on each side of the engine like everybody else, they often placed it above like their 4inline prototype or their beautiful 126CK serie : D

If tyre size is not defined, on what basis are the teams designing their 2014 car? Has FIA defined the sizes?

Do you have more information on this engine?

Also Hart placed the turbo on top on its 415T Mk1.
