If low-profile tires are supposed to make your car faster, why

Because low-profile tires don't necessarily make you faster. It's mainly about aesthetics.

And this

Its more a roadfeel thing

But what if it looks awful?

This is just wrong.

Personally don't really like low profile tires just for practical reasons. Honestly, your sidewalls are going to flex a bit more, but you lose ride quality, and the possibility of getting a pinch flat is higher.

Modern cars are heavy so they need big brakes.
You need big rims to clear the brakes.
Big meaty tires won't fit without making the wheel wells and arches ridiculously huge.

F1 cars are light so the big sidewalled tires don't get squirmy in the corners. Dragsters only go in a straight line and need the sidewall wrinkle to hook up

Because Formula cars have strict regulations regarding their tire dimensions. That's also why they don't have turbos, or CVTs, or rocket engines, or spikes on their wheels.

Look at GT racing circuits where the tires aren't as regulated, you'll see much slimmer tires there.

F1 has turbos.

Right, but they didn't for awhile.

Also even in what you call "GT racing circuits" the tires aren't exactly low profile.

Weight is also an issue as a smaller rim and taller tire is lighter than bigger rim shallow tire.

First image on Google, seems pretty low profile mate.

Second result on Google.

Neither of the examples you posted are low pro, even when considering this specific racing application.

Those sidewalls are still taller than an average commuter vehicle's.

F1 wheels are restricted to a diameter of 13cm.

They're really not.

in f1 the tyre forms most of the suspension travel

Seems like you don't know what low profile tires are. Of course you need some sidewall height to let the tire work

Pirelli motorsport director Paul Hembery says Formula 1 should make a "huge jump" in tyre size and not get fixated on proposals for 18-inch wheels.

...

Michelin has joined the push for 18-inch wheel rims, but despite showcasing such a design on a GP2 car ahead of the Monaco Grand Prix in May, Pirelli has reservations over that concept.

Hembery told AUTOSPORT: "To be honest the only appetite for going to 18, or something else, has come from external factors.

"The teams are actually very consistent by saying they want to stay with 13 and you can look at it two ways.

"I could sit here and say 18, to be honest, isn't relevant at all because that's what we put on our standard cars.

"In reality, if you want to do something dramatic, you'd sit on 19 at least, but probably 20 or 21 because that's where the top-end [road] cars are these days.

"So if you're doing it, you'd want to make a huge jump.

"The majority of our circuit racing is done on 18-inch tyres already, so 18 isn't that unique.

"Some could argue 13 makes you stand out, and there are some people and some fans who say that.

"We know that to make an 18, 19 or 13-inch has the same amount of technology and technical requirements, so it's almost irrelevant."

There is a greater consensus over the width of the tyres themselves, with a proposal for switching from the current 375mm width to 420, a tyre last seen on a F1 car in 1992, for the 2017 season.

"The only area where they all seem to be very much in agreement is going for wider rear tyres, which when you see it on a car looks pretty dramatic," added Hembery.

"It does make a car stand out.

"It is a very big visible change that stands out and people will look at that and go 'phwoar, that's a tyre!'

"Even the 18-inch we ran in Monaco looked different rather than 'wow', but the wider tyres do have that wow factor."
