If you want maximum grip for the track, go with 19” rims on 265/35 RE71 or R888R’s. You’ll thank us later.

Nice. Looks like the RE71s are the better tires for mostly street use?

For 19 rims are you using Tesla 19 rims or aftermarket?

Smaller diameter tires essentially reduce your power above base speed (~60kmh) by making your motor operate at a higher speed. I wouldn't do it intentionally unless you are one of those crazy autocross guys that install 13" wheels on Miata's and smaller brakes.

Highly recommend VMR wheels. They will machine the center bore and bolt pattern to OEM specs which means no hub ring. I have 19x9.5 ET 35 with 275/35 R888R’s. This is a very aggressive setup.
For street use I’d recommend going with kbecks setup. VMR V710FF 19x9.5 ET 33 and 265/35 RE71’s. This will give you a comfortable clearance between wheel and suspension.

Good point. I forgot that power drops off pretty quickly above 60 mph. Interesting that it still pulls to 155 mph.

VMR V804 19x9.5 ET 35. Because I went with 275/35 Toyo R888R’s I need a 3mm spacer on the fronts for adequate suspension clearance. If I had to do it again it would get VMR V710FF 19x9.5 ET 33 with 275/35 Toyo R888R’s or RE71’s. The extra 2mm would give me enough suspension clearance. The extra 10mm tire width does help.

You have just answered the question I was wondering. What is the ideal offset for the P3D folks if they wanted to run the maximum 275 wide tires on 19"x9.5. Though its probably overkill and a range hit on the street, you will appreciate the extra wide shoes on the track. Looks like 32 or 33 offset is the winner, though it might be questionable with 18"x9.5 or 10" rims, due to the shape of the suspension.

The +33 with 265's on a Performance car works great for me. My only complaint (and it's not really a complaint) with the RE-71R is that they are so quiet compared to the PS4S when cornering hard. Without tire noise (and obviously engine noise) it's super tricky to judge speed and how close you are to the limit on track.
On the highway though, the RE-71R is much noisier than the PS4S

Is the +33 because you have the thin rotors that come with P3D+? If I have the MPP rotors, those are not thin so would +35 be OK with 265 on 19x9.5?The +33 with 265's on a Performance car works great for me.

They have pretty crummy longevity on the track. They are super sticky though. The Dunlop Direzza Star Specs are not quite a grippy as the RE71Rs but will have better longevity. If we are willing to sacrifice some grip (still WAY better than PS4) Dunlop is an option.
I would not get R888 unless you track the car almost exclusively and live in warmer conditions. Those tires SUCK when cold and when worn down, do horrible in water. They are a very sticky tire in track conditions, its a streetable R comp but wont not suggest for any sort of daily driving.
