explaining f1: tyres 🛞

first post in this series (will it be a series? we’ll see)

recently i think we’ve had some particularly interesting races in terms of tyre strategy and i readied in suzuka that i don’t totally understand it all, so this has been my little research project on tyres!

pirelli

pirelli are an italian tyre manufacturer who have been supplying f1 tyres since 2011. unlike some eras of f1, pirelli is currently the exclusive supplier in the sport.

in 2022, pirelli introduced a new 18-inch (the previous being 13-inch) tyre as part of sweeping changes to the technical regulations of the sport.

compounds

pirelli’s range is currently comprised of six ‘slick’ compounds (referred to as slick because they lack the grooves of normal road tyres - this is because these grooves exist to dispel water, something necessary for road tyres but that slows down an f1 car when not necessary) tyres, along with ‘intermediates’ and full ‘wets’ to account for weather conditions.

the six slick compounds (from hardest to softest) are referred to as follows: c0, c1, c2, c3, c4 and c5. from this range, pirelli pick three to be used at each grand prix, based on the track characteristics and climate.

the highest of the set is marked red and is known as the soft, the middle marked yellow and know as the medium, with the lowest marked white and known as the hard (intermediates are green and wets are blue).

theoretically, the softs have more grip over short periods of time, making them faster and better for qualifying runs. generally, the hard and medium compounds are more favourable on race day because they last longer.

rules

on most weekends, drivers are given 13 sets of slicks, 4 intermediates and 3 wets, with a set of softs reserved for drivers who reach q3 (the final round of qualifying). all drivers must return 2 sets after each of the 3 practise sessions, meaning only 7 sets are left for qualifying and the race. drivers must also use at least two different slick compounds during the race (provided the weather is dry).

on sprint weekends, the number of dry sets are reduced to 12. after the sprint, drivers must return the set they completed the most laps on.

tyre allocation is on a per-driver basis, teammates cannot share or swap tyres. in bahrain in 2020, mercedes mistakenly put bottas’ tyres on russell’s car when attempting a double stack. the team was fined €20,000 for this.

drivers must run the same compound on all four wheels at all times.

strategy

tyre plan for the weekend is the decision of the team, generally based on information from pirelli, observed degradation over practise, the circuit and the weather forecast.

if rain is expected, teams can draw from their wet weather allocation, and so they don’t need to be as cautious with their dry weather tyres. if it’s hot, teams have to make sure they can cover plenty of tyre changes.

if track layout means overtaking is tough, teams may want a higher number of pitstops to stop drivers getting stuck behind rivals. also, if the track is walled (and so safety cars are more likely) teams may plan for more stops.

terminology

scrubbed: teams often ‘scrub in’ a set of tyres by running them briefly during practise, this means that when they are later used in the race, they warm up much faster than brand new tyres.

blistering: when the inner part of tyre heats more than the outer, creating minor explosions which damage the surface of the tyre.

graining: when the outer surface is hotter than the inside of the tyre, leading to the outside rubber flexing, breaking and sticking to the tyre.

flat spot: a patch where the surface of the tyre looses its curve. this is usually caused by a driving locking up by breaking too late, meaning the tyre scrapes along the ground.

deg or degradation: refers to a steady loss of tyre performance due to general wear.

this is a poster i made for my call to action assignment in humanities! it's a bunch of basic and easy stretches for people who sit and work at a desk all day (me)

the idea is that you'd put the poster up above ur desk and do the stretches every 30 minutes or so,, the whole routine won't take more than about 6 minutes to complete and when done regularly it can prevent wrist, shoulder, neck and back pain! :)

all these stretches can be done while sitting (although i HIGHLY recommend you stand up and move around while taking a break from working)

you can get a free digital copy of this poster here on my gumroad!

and you can order a print/poster here from my inprnt!

I'm getting so sick of major female characters in historical media being incredibly feisty, outspoken and public defenders of women's rights with little to no realistic repercussions. Yes it feels like pandering, yes it's unrealistic and takes me out of the story, yes the dialogue almost always rings false - but beyond all that I think it does such a disservice to the women who lived during those periods. I'm not embarrassed of the women in history who didn't use every chance they had to Stick It To The Man. I'm not ashamed of women who were resigned to or enjoyed their lot in life. They weren't letting the side down by not having and representing modern gender ideals. It says a lot about how you view average ordinary women if the idea of one of your main characters behaving like one makes them seem lame and uninteresting to you.

i was curious so i looked up what story alana was reading to abigail and it's about a inmate who escapes a prison and ends up killing an entire family. she was reading that to a teenage girl who just narrowly escaped being killed by her serial killer father. anyway i never want to hear about how normal and well adjusted alana is ever again
