My Elise came with two sets of Hankook F200 medium and hard slicks - against my better judgment I didn't just sell them and have been running them, they pretty much only get faster the deeper in the session you are. They're not the easiest to drive, but that partially might due to the car.

I believe slicks need a lot of heat in them to work well, so it might be that they only reach operating temps later in the session. It might be fun driving ever increasing pace without fear of losing grip, but I would prefer tires that warm up quickly and perform the same throughout the session (goes both ways - not greasing up like 3-lap-wonder tires nor not reaching full grip until the last lap). This way I can explore the limits of the car.

They seem to take a lap to not be skatey, which is comparable to the RE71RS when I ran it on my BRZ. The RE71RS would get greasy after maybe two laps for me.
The car is 1700lb without driver and it makes 220whp NA, stock aero. It's a missile and also wants to murder you, pretty fun.

In my experience, if overdriving A052s I can find myself running out of grip after a handful of laps. But driving at 9.8/10ths instead of 11/10ths, I've found I can do LONG stints without losing grip. As mentioned previously, in an endurance race in an S2000 on 255/35-18 A052s, I set the fast lap of the event on like lap 100!
For me, A052s have been the go-to tire bacause: 1. all the grip from lap 1 turn 1 2. wet grip is *amazing*, and sliding grip in the wet allows you to push without risking doom... 3. can run long stints without losing grip, if do not overdrive! We'll see where the new Hoosier 200tw falls soon enough I hope! Honestly if they were available in my sizes I'd be tempted to run a set in time trials a couple of weeks from now, but would have to be 225/45-16 for the Miata or 225/45-17 for the BRZ and I'm only seeing 18" and 19" sizes.... |

Looks like Maxxis has a new 200TW too.

Should also mention, the S2000 had a not-too-huge rear wing and modest front splitter but IMO not enough to really affect tire life. Track-only "race car", but it was ballasted up to 3100+ lb., so not exactly a lightweight race car! |

I get an entire season (20 days) of autocross out of a set of A052s when single driving.
There wear rate can be very vehicle and setup dependent. |

FWIW, known fast veteran driver was only 0.5s faster on these Hoosiers vs. NT01s at NHMS (South Oval config) in his well set-up and fast C5 Z06. And only for a few laps in their first session. Subsequent sessions they were almost exactly as fast as NT01.
Oh wellz... |

Only half a second faster? On a 200TW tire vs. a 100TW tire? I'm not sure I'm following your logic here.

Regarding NT01, GRM sez: Quote:
However they give the A052 an "A" grade for time trial pace, and the NT01 get's a "C". Weirdly both get a "D" for heat tolerance. As usual take with pinch o' salt but I'd still bet on A052 being faster than NT01... Last edited by ZDan; 10-22-2024 at 05:19 PM. |

Oh, for sure. I was referring more about the classification of TW rating. I guess my commentary is aimed more at the NT01 being not worthy of its 100TW rating than at the Hoosier. It would sure be nice if ratings on tires actually meant something...

It's a treadwear rating, lower number doesn't necessarily mean more grip. Tire manufacturers don't really have any requirements on how they rate for treadwear, and of course the super-200s are given that rating because of rules requiring 200tw minimum for some autoX, racing, time-trial classes. I.e. maybe they should be rated lower if based strictly on wear rate. I mean in the real world on the street, normal usage, I would bet their lives would be a lot shorter than the same manufacturers' 400tw tires!
