Why don't F1 cars use donk tires? They are the most responsive tires ever made
Jackson Reed
Why don't you know how to English? What the fuck
Jaxson Taylor
That was back during slavery. Only when we empowered the blacks did we truly understand how dank the donk really was.
David Watson
can someone answer this seriously, id really like to know
Brayden Carter
Do you have any information about the fucking barely existent rubber on those?
Who manufactures shit like that? How much does it cost? How long does it last, what PSI do you have to run?
Jaxson Ward
Probably because the cars had to be close wheeled and at the same time, incredibly low to the ground. Even adding another inch to the size of the tire means you need to cut into the bodywork further to keep it close to the ground.
If you're asking why the rims weren't bigger, probably because aesthetics weren't a priority.
Adrian Taylor
rubber bands main...
You run a car like that, you dont care about the price of no fuckin tires white boi
Zachary Turner
>implying big wheels are better Yeah nah. Look at f1.
Isaiah Lopez
I suspect it was because a big fat tire could handle bumps in the early race tracks that were shitty better than a stiff skinny tire. Maybe it had to do with tire technology and that was the only way they could get a tire wide enough, it had to have thick sidewalls
Dominic Phillips
>Were the aspect ratios just not available?
back in those days 60 aspect ratio was about as low profile as it got so yeah pretty much
Tyler Baker
This. It's pretty much up to tire technology and racing regulations
Elijah Adams
This, low profile + lots of width is actually really hard to manufacture/design.
Connor Hughes
I got another, less niggerly question:
Why did cars like the 330 in OP's pic and the GT40s had a spare tyre on them? I can understand if it was the case of cars that also run the Mille Miglia or the Targa Florio but why on Le Mans-spec cars?
Ryan Ortiz
Because track response time could take very long and better safe than sorry.
In regards to the wheel size question, Carroll smith says it was also about weight
John Smith
I'm guessing because bias ply tires a shit and would puncture more easily, and because the pits are very far away and they didn't have support/tow vehicles like they have today.
The Le Mans of yesteryear was about racing at max speed, and seeing who exploded first. Today, we're trying to finish the race first, then racing fast. It just happens that cars are rather durable these days, so they drive at top speed.
Grayson Phillips
literally the opposite retard
you could drive flat out because the car would explode sometimes in an actual fireball
the only drivers who were driving flat out were the designated "hare" that would push their car incredibly hard to set the pace for the opposition so that their cars would explode with the hare's car so his team mates can win in the end by driving conservatively
Nolan Carter
The heavier a wheel, the more unsprung mass, the more force required to rotate and to turn.
Smaller wheel = stronger, lighter and less of the above than a larger wheel.
Stock 20" rims are just a customer driven wank-factor.
Jaxon Wilson
>Maybe it had to do with tire technology and that was the only way they could get a tire wide enough, it had to have thick sidewalls I think this for the most part. A taller wheel also means more angular momentum and generally more unsprung weight which means heavier suspension components which also means a heavier car.
Cars then relied on mechanical traction much more than the downforce the have now.
Mason Cooper
Read this in Mario's voice
Wyatt Roberts
because race tracks back then were far harsher on the suspension. But the actual reason was that there is nothing inherently wrong with high aspect ratio tires from a performance standpoint.
The only actual advantage low profile tires have is that by twisting less under cornering, they heat up less so the tire temperature is more stable throughout the track, so you can use more aggressive compounds for grip more consistently, even if the durability suffers. Modern rubber is a lot grippier and durable than old rubber, and it doesn't have to last as long as old tires had to (some of which would last several races in the 60's).
Low aspect tires have a disadvantage in terms of straight line grip since they're not as flexible though, which is why drag racing tires are so thick.
Tyler Bell
old sports cars are tiny.
Carter Hernandez
They look sexier and are more fit for purpose.
Caleb Sullivan
...
William Howard
holy shit the porsche 917 is smaller than a 914
they look fucking ginormous in pictures
C3 corvettes are fucking tiny IRL, and C4 corvettes are even smalller
Hudson Long
C4's are not tiny you stupid fucking retard. C4's are fairly large cars for their time, they're longer and most coupes.
Julian Bell
Yeah nah, pirelli ran tests with 18 inch wheels vs the current 13 inch and found out they are almost 9 seconds faster.
Mason Gonzalez
I believe it's because the tires acted as part of the suspension, so a thicker tire allowed more variety in suspension tuning.
Thought it was because the tires flexed under hard cornering and would create a larger contact patch.
Colton Perez
This is the correct answer
Jacob Jones
9 seconds faster in what? A 1/4 mile drag? I call bullshit.
Kevin Davis
Big sidewalls act as suspension, letting the cars run less suspension travel and therefore less body roll.
Luis Myers
lol it's still the same in 2016.
You didn't think all those road cars had tiny low profile rubber for performance reasons right? it's so the wheels can be as big as possible for styling reasons.
Blake Gutierrez
They would also run at lower PSI to stick to the road/track.
Jose Baker
having space to carry spare tire and having seating for an assistant navigator/mechanic persisted all the way into the 1980s till the regulators said fuck it no one even uses that shit no more
Parker Morris
low profile tires were pretty much impossible to do back in the day, so if you wanted THICK you had to also have tons of sidewall. Nowadays you can get away with much, much thinner tires and still have 275s all around so it's no big deal. To people saying that it was actually more effective than having low profile tires: small wheels = small brakes = terrible heat dissipation old race cars would fucking kill for modern tires.
Nolan Foster
another thing is that with the introduction of slick tires small wheel diameters fell out of favour due to overheating the softer compounds too much >think wheel rpm per mph
I'm absolutely ashamed that nobody mentioned crossply tyres.
Oliver Reyes
Veeky Forums is full of retards, newfags & stancefags that have no idea what the fuck they're posting.
Kayden Morgan
According to The Grand Tour, GT40s used 15-inches because at 16-inches they became dangerously unstable.
Juan Campbell
holy shit that looks so much better too
Brody Sanchez
On top of things like and and you might need to remember that back in the old days ultra light hard metals weren't common. Maybe they were saving weight by using big tires with small rims over giantic rims with small tires.
Evan Ortiz
wat
Magnesium was used everywhere back in the day
Cameron Garcia
Was it lighter than tire compound?
Jonathan Phillips
15x7 mag Minilites were 10.5 lbs each a modern racing tire to fit it (205/50r15) is 20 lb each
I couldnt find vintage tire weights but Id say yeah mags are lighter
