I'd like to take the tires in this list and resort them into two lists, one with the quickest-lap-time tire listed first, and one with the longest-lifespan tire listed first.

This is the idea:

1. 'Quickest tire'
2. 'Second Quickest tire'
3. 'Third Quickest tire'
4. 'Fourth Quickest tire'
...

and

1. 'Longest Lasting tire'
2. 'Second Longest Lasting tire'
3. 'Third Longest Lasting tire'
4. 'Fourth Longest Lasting tire'
...

This is the list (sorted alphabetically):

Advan A048
BFGoodrich G-Force R1
Hankook Ventus Z-214
Hoosier R6
Kumho Ecsta v710
Maxxis Victra RC-1
Michelin Pilot Sport Cup
Nitto NT01
Toyo Proxes RA1

Some of the hierarchy seems obvious. But some of these tires are new.

If there are other tires that should be added to the list, I'm interested in that, too.

I'm going to post it on a few different forums and then tally up the consensus.

If you trust UTQG treadware ratings, then the two lists would look like this, more or less.

Lap time and grip:

Kumho Ecsta v710 (30)
BFGoodrich G-Force R1 (40)
Hankook Ventus Z-214 (40)
Hoosier R6 (40)
Advan A048 (60)
Michelin Pilot Sport Cup (80)
Maxxis Victra RC-1 (100)
Nitto NT01 (100)
Toyo Proxes RA1 (100)

Long-lasting:

Toyo Proxes RA1 (100)
Nitto NT01 (100)
Maxxis Victra RC-1 (100)
Michelin Pilot Sport Cup (80)
Advan A048 (60)
Hoosier R6 (40)
Hankook Ventus Z-214 (40)
BFGoodrich G-Force R1 (40)
Kumho Ecsta v710 (30)

Still, that doesn't seem entirely accurate.

Jack, the UTQG number is relative only to others tires made by that same brand. It is not a valid comparison between brands.

This is a good idea Jack, but I wonder if there is someone that has run all those tires on the same car. I will give you my list based on the tires I have run.

Lap time and grip:
1) Hoosier R6
2) Hankook Z-214 C51
3) BFG R1
4) MPSC

Long Lasting:
1) MPSC
2) BFG R1
3) Hankook Z-214 C51
4) Hoosier R6

I had a mention of that in the post because I thought that was the case as well. But I just looked it up and it appears as though that all changed in 2012. Now the treadware rating is at least supposed to be an NHTSA-specified test involving a reference standard tire on a specific track and is the same for all manufacturers. I don't know what the oversight or enforcement mechanisms are, however. It might be that manufacturers are still allowed to fudge the numbers.

The rating increments are supposed to be 20 points, which makes the Kumho Ecsta rating not make sense. Maybe that number will change on the Kumhos in the near future.

I would be very surprised if all the manufacturers came into line with each other. Sounds like a pipe dream.

Still don't know why you guys don't seem to be able to get Yokohama AO50's? Perhaps you can. You should try. They are far better than the AO48's. Same with the Hankook Z221. Best 2 R specs available today. Having said that, you don't list the Hoosier A6 as an option? I'm sure you could use these on your car without issue. They're not just for AutoX.

Lap time and grip:
1) Hoosier R6 (To get the most perf out of an R6 requires you to change your driving style a bit. They are loose going in, but they stick like crazy once the car is loaded...if you can "see" through the looseness and have faith that you will survive, rather than back off a bit, you will be quite a bit faster on them)
2) BFG R1 (pretty close to an R6 except for the 1st heat cycle of the R6 which is magic)
..
..
3) NT01 (they start off stronger due to the tread design, but eventually about the same as an RA1)
4) RA1
..
..
5) MPSC
..
..
6) AD08/RE11

Long Lasting:
1) Street tire (AD08/RE11)
..
..
2) NT01 (Never heat cycled out, lots of tread, good for heavy cars)
3) RA1 (I've never heat cycled them out, same rubber as NT01, needs to be shaved)
4) MPSC (Hard to tell because the grip is a long long way off the rest)
5) BFG R1 (10-15 cycles)
..
..
..
..
5) R6 (5-8 heat cycles, on a heavy car without a good camber curve (like a BMW E46) you will cord them in less than 8 cycles.

Not to get this off topic, but the bold is not correct according to the engineers at Toyo and Nitto that I have spoken with. They are different rubbers.

Interesting I heard the opposite (maybe speculative), but It was not from an engineer. They seem pretty close in terms of perf and heat cycles. I guess there is more in common between the NT01 and RA1 than with the 888....

The RA-1's (Circa '07) had a treadwear rating of 40. They were re-rated at 100, so as not to compete with Hoosiers et al in points-based classes. Pretty sure they did not suddenly start lasting over twice as long (in fact the opposite might be true). Purely marketing/political move. Very little hard science in those numbers, IMO.
