Bigger wheels, low profile tyres

If they do it, it will be an end to overtaking under brakes, they can pull 5G under braking today, I genuinely fear for the drivers how fast they will be able to stop with brakes scaled up to suit 18" wheels.
Won't make any difference.
The brakes are already powerful enough to lock the wheels.
The limiting factor is the tyre grip available (both compound grip and downforce)

I think Michelin wanted F1 to move to 18 inch wheels if it was going to supply to F1.
As with most things F1 I take the 'official line' with a bucket of salt. I've heard it's to limit brakes, but as some have already said they've managed to pack more than enough braking power in to the space they have now.I've always assumed the tyre makers wanted the maximum amount of "advertising real-estate" so I would be surprised if Michelin would have pushed to give up all theirs in favour of OZ's.
If they did change it, it would have to be between seasons, as under the current regs the tyres form part of the suspension.

Put 15's on a caterham, and you completely ruin it. I can only imagine what it would do to an f1 car...
Considering they run ACB10 crossly, not that supposing a change in wheel and to radials is going tommake a difference!Does not make it wrong, just needs the suspension change to suit.
F1 on 13" rimms is laughable these days...
Scuffers, is there anything you're not an expert on?
As per usual, you're talking ste. Very few caterhams run acb10's - the superlight r came with them, but most people racing use cr500, zzr, or whatever low spec avon radial is dictated by the academy series these days. Oh sorry, the sprint / hillclimb mob tend to favour the kuhmo v70 soft.
Obviously if people were to move from one to the other, they would change the setup. Thats why there are 2 sets of de dion ears.
Anyways, When f1 engineers had free reign of wheel size, they were going smaller not larger. F1 on 13's is not laughable, it's logical - they are the rit apecification for the application.

you don't have to be an expert to look at just about any tyre makers listings and see that just about *ALL* GT tyres are 18" and have been for several years now (to the point that getting 16 and 17" ones is becoming increasingly hard).
as for Caterhams, if you want to race one, ACB10's are still the best tyre out there for them, just because somebody has done a tyre deal to run XYZ does not make them the best tyre available (see Pirelli in F1 for details!)
F1 run 13" because it has done for years, no other reason
From a chassis perspective they would love to run lower profile tyres than the suspension could do the majority of the job instead of the tyre (acting like an un-damped spring - hence J-dampers and mass dampers etc)
Look, this is not hard stuff, the info is out there, your just being blind/dumb

Whilst I quite often don't agree with Scuffers the assertion that every car handles better on 14" wheels is rather simplistic isn't it ? As per usual, you're talking ste.

Barring caterhams and F1 I'm struggling to think of any racing car that uses 14" or below.
So why do formula 3, 3000, renault, and various hillclimb cars not run 18's instead?
You need the compliance in the sidewall to be able to carry curbs etc, and there is no advantage to having larger brake capacity like there is for endurance racing.
Face it, the only people calling for massive rims are the marketing people. F1 engineers are not asking for it, at all.
