Yeah, now that you say it that way, I'm not sure either. Either way, tire pressure recommendations are: 36 front 32 rear.
Much more reasonable than what is posted for the JCW.
As for track pressures I can only speak from my experience and it is opposite of that. For a counterclockwise track with 215-45x17 200tw tires, I will start, cold, with 29 to 30 psi in the left front 30 to 31 psi in the right front, 33 in the left rear and 34 to 35 in the right rear. This will put me close to 38 psi front and 37 to 38 psi rear (my targets). This is in my 2600# R56S, which might be close to the weight of the GP3 (I found another post citing 2600 lbs for that car).
I have also had experience with 100tw tires and the pressures were similar. My guess is, that YouTube reviewer had the tires on his GP at the recommended values. If he was at 36 psi front, I am not surprised that they would wash out when they got hot. They were probably at about 45 psi hot, which, in my experience, will cause that, especially with the rears so low and likely being at their optimal pressure. In other words, a lot of grip in the rear and no grip in the front. A recipe for understeer. Seems like a MINI “safety” thing, where understeer is considered safer than oversteer. Personally, I think the guy could have done better if he had checked the hot pressures.

Reason: Fix typo
Next week I put on 235/40 Federal, the tires are a joke!
To the car itself. Today it was the first time I was using the car at high speed all off. The good message you can brake and accelerate quite handy. You can concentrate just on revs 3000-5000 and use this auto toy to flip through the gears, I don't think manual comes close to it. You must keep the car in a flow.
After my Guru has thrown the runes it will be VT2 plus Rüstsatz AERO SP3T.

And to think, 225-45s are a struggle to fit into the wheel wells of my JCW. The fenders of the GP3 may not be the most loved feature, but if you can squeeze 235/40 tires inside those wheel wells, then they do provide the functionality that the rest of us could use.

The price is around 100 Euro incl. tax, the Hankooks starts at 300. The original 225/30 ditched a curb, therefore i need replacement. The spades will be very handy to homologate bigger rim size were normal production cars have to quit. Such is the rear wing, who needs some angle ;-)

What tires come on the GP3? I assume they have to be RFs. I have Bridgestone Turanzas (225-40-R18) on my JCW Clubman, I think ER33's a summer tire, pressure is 38 psi front and rear. $250 per tire. Hope they wear better than the ones on my JCW Coupe I replaced those at less the 20,000 miles as I recall.

All American GP3s come with non-runflat summer Hankook tires and a small inflation pump with that slime stuff. They 225/35/18 Hankook Ventus S1 Evo Z.
However, the 2020 press car came with the optioned Hankook Ventus TD semi-slicks in a special 225/35, which seem to only be an option for those who ordered the car without AC, something I could not do. There are suggestions that say they will be offered as a packaged but my dealership couldn't find them in the US, because I would have bought them together.
I can say that 235/40 should fit on the car with little effort - only concern is tire to shock, but I also know 225/40 provides a lot of track tires and I have confirmed that will fit based on size.
There is no info out there about these tires and a general lack of info about the TD tire, even on the Hankook or Hankook competition tire websites. Am I missing something? How does one get a replacement, other than going through the dealer?
I got an “almost good” picture of the Evo Z tire on the MINI I saw here, but can’t read the tread wear number in the picture. Seems like you would do well to go for the Yokohama A052s which come in the 225-35 size when the Hankooks wear out. If I was to do a semi-slick (100tw) tire, I would get the Toyo R888R, which can be had in either a 225-40 or 235-40. But to get the most out of those you would need about -3 deg of camber.

the S1 EVO Z are 200 rated, not that that tells us much. They are special, I guess, but I will likely go to the Michelin PS4s if I stay summer tires.
Here is the info on the TD Z221...https://m.hankooktire.com/content/ht...s-td-z221.html
It is a European style tire which can only be purchased through discount tire in the US and the ones on the GP3 are of course a special size. Those who use it generally suggest it’s a very strong tire equal to the Cup 2. I wouldn’t know though.
Both the R888R and the Michelin Cup 2 are available in both sizes and offer more options (I may go with Cup 2 only because I have seen them be run on the street without horrid results, though I know the R888R are faster.)

Reason: Clarity and grammer
All tests were made with the street tire, including the Nordschleife blew up. it's said that the TD is around 15 sec faster one the Nordschleife than the test tire.
To buy a 225 TD Hankook from a MINI dealer needs a lot of autism if you can get a 235 for half of price.
We will run several setups including 17, by the way, the only good thing about that GP2, the 6pot is a homologated pick ;-)

Are you saying that the 7:56 second Nurburgring time was done on Ventus s1 and not the td, and that the td should have shaved ~15 seconds off the time?
also, what’s the part number for the 225 td? And what’s the price? Are you in Europe or America? I am not disagreeing that you shouldn’t pay double, but you don’t have to go around throwing the autism word out just to make a point. Don’t be a jackass.

It is interesting that the 225-40 and 235-40 tires have almost the same tread width (less than 0.25 inch difference) and the 225s are $50 less expensive a tire. Also the GP wheel (8” wide, right?) is optimal for the 225 and slightly small for the 235... Maybe the 225-40 would be a good choice if not looking for 10ths of a second on the track. Just a thought.

All of his posts are running through something like google translate, I doubt he really meant something offensive. He's in northern Germany based on where he picked up his car.
A source I don't doubt, which you also use for your cracked Taiwan wheel sensation ;-)
What tire MINI used for their undocumented 7:56 you should ask them, as well what the part no for the TD is and price. I don't need that
Sorry for my bad English, I write in German and you use Google,you might do that better ;-)
This article just showed up. They drove the GP3 on a 1.5 mile track and it did pretty fast, better than some way more expensive cars. Stock tires. Traction features all off. Lotta torque steer. Preferred MT in GP2 (thought that car was
more powerful). But LOVED the car for regular twisty road driving like we do. Pretty stiff ride like they all say.
Lime Rock Park - aka “the Bull Ring”...
They are on the turn-in to the uphill and the turn-off just behind the car is the chicane that the IMSA GTLM cars take. It is fun, but not in a MINI as it is a 2nd gear turn and the shift to 3rd is in a bad spot, with a lot of lost shift time... It was just as quick for me to take it in 3rd and not loose the time. The actual up hill part, where they are, has a big pucker factor to it. If you can get by that, you can catch a lot of cars there.

Yep it's the Bull Ring alright. The said the GPs time was 1:05 I think. Which according to them was pretty close to the record time. They thought that revving the engine higher would have helped sometimes but the AT or even the MT option would make it shift sooner.

no hard feelings and hopefully it can help Clutch Wotan understand the English language better.
