They're a lot faster than NT-01, dropped 3 seconds at Thunderhill East w/bypass, from 2:00.00x to 1:57.16 just swapping from 275 NT01 to 295 AR-1.

Hoping Toyo RR can do a similar pace, and I hear they're more consistent. It should be a deal!

How many heat cycles would you normally get from the NT-01's?

Thanks for the info!

[kyippee]

Dreamer99 30-40 for NT01. AR-1 typically get ~16 before the grip drops off sharply

Wow that's a huge difference!

[kyippee]

Yup... and fsmtnbiker is even faster on AR-1. He's got less weight in the car, same AR-1 tire sizing, and more aero. (big wing and big front splitter), running 1:54.5

Alright, you got me hyped to try the AR1 for the GTA event, especially after I just killed NT01 in 21 sessions. I've already got a new set of NT01 that I'll hopefully kill before then ("hopefully" because I need to get that new PS pump in asap). 275 just isn't enough. My main competitor is on the same sized NT01 on a 2600lb S2k with ~460whp and more aero, lmao.

Were you running 275's? Surprised how fast you went through them even given your upgrades. What corded, the fronts? Inside/outside? What's your alignment?

AR1's are faster but don't last longer than NT01's. Going to a 295 from a 275 would improve life a little bit, but that's due to size not compound.

Front: -2.8-2.8 camber and zero toe
Rear: -1.8-1.9 camber and .19deg total toe
The session the cording happened it ended up being the inside of the front right and the outside of one of the rears. I swapped the tires around every few sessions so the wear was not too uneven. Probably could've gotten a few more sessions if I was even more on top of it. Worth noting the right front gets hammered at this track much more than others, followed by right rear, left front, and then left rear. Maybe I'll try higher pressure with the next set too. Was running 35 hot measured back in the paddock.

Also, I don't do any chill laps out there.

Interesting that the front right corded on the inside with that amount of camber. The rear sounds like it could be helped with a bit more negative camber. How worn down was the section of the tire that wasn't corded, and the left side tires?

I haven't been to the Ridge in my E92 yet, but that wear sounds strange to me.

Well keep in mind each tire has been moved multiple times. In fact the front right was originally the left rear, which is along for the ride more than any other tire on this track, and at a portion of the tire's life where the tire appears to wear the fastest.

I suspected that. How worn down was the rest of the tire other than the corded section?

Here is a picture of my front 275's with ~35 heat cycles on them. I was running competitive times for my class (ST3) on these, so they've been worked fairly hard to say the least. They had been flipped once though and I would flip them again before using them. My outsides are wearing more - as you can see. This is with -3.5* and 0 toe. I suspect these would get me another ~10-15 heat cycles, based on previous experience.





Obviously different tracks wear tires much differently. My track is what I'd call average/normal on tire wear, so keep that in mind. I don't if the Ridge is normally considered hard on tires or not in comparison.

Just trying to help

[Bartledoo]

At least one of my tires looked like that on the first day hahaha.

Below is a photo of one with inside cording.

The other corded one faintly showed the inner circumferential groove but was more thrashed on the outside. Do you guys get both grooves erased before cording? If so maybe I need more pressure. Also going to get another alignment done this week to see how out mine is.

Wow, after one day hey. Yes, I wear them down to a 'slick' before I cord them. Any idea what your car weights with you in it? It's hard to tell from the picture, but perhaps you're correct in needing more pressure.

I have been eating the outside front with -1.8, -2.5, -3.0 and finally I am on -3.5 but not enough track days (3) to draw conclusion.

Also, I had a virtual coach look at my data and I have a problem being on the gas too early. That also eat the outside.

So, my hope that with combination of -3.5 and correcting my driving, i will be wearing front tires more evenly

Haven't actually weighed, but based on my math between 3450 and 3500 full tank without me. It has the same splitter as dogbone, but with somewhat large tunnels, and an APR GT-250 with larger endplates. What are your rear settings?

Yeah, so my car is a bit lighter. When I ran the above NT01's I was -3.4* front with 0 toe and -2.3* rear with ~1/8" toe in per side. I've now gone to -3.9* in the front due to the outside tire wear I've been having. Rear has stayed the same. Also, I'm running 1/4" rake. I've been running 34psi hot pressure for the NT01's.

Cool thanks for the help! I think I'll up the camber and pressure. Also, I've heard our tracks are pretty abrasive. Makes sense as they need to grip in the wet given it's the pnw.

I think I’ll try the 315 AR1s if I run them again. The 295s easily fit, and the extra tread and heat capacity would be nice.

The RRs are a touch off the pace of the AR1 and fall off some with heat, more than the AR1. The 295 RRs are a great deal though, hard to argue at the price.

I don’t have enough room in the car to take 2 sets of wheels/tires with me, but I’d really like to run my A052s back to back with either the AR1 or RR. I suspect they are faster but only for 1 lap. Super curious to run in GTA trim on the A052s just to see if the car is remotely competitive without significantly more power. I suspect I already know the answer...

Easily fit up front? What suspension are you running?

Also interesting you found them fall off more then RR's, I've found the opposite!

[Bartledoo]

The AR1 seem to run really narrow. Seen people running them on 18x10 and they aren't even that bulgy.

[fsmtnbiker]

Yeah the 295 is slightly stretched on a 10.5” wheel, I feel like I could put the 315s on them without sacrificing contact patch.

I’m still real tempted to just buy 295 Hoosiers and try to win some via NASA TT. With the laptimes I’ve been running I think it’s a solid strategy... just an expensive gamble up front.

Which region would you be running? Which TT class?
