Toyo Proxes RR review
Brief review of the newish DOT/R-comp track tire by Toyo, the Proxes RR.
Some details/characteristics:
I picked up the first set as an alternative to the Nitto NT01. Definitely softer, grippier than the NT01, as evidenced by the much lower treadwear rating. Much quieter than the NT01, although they still manage to chatter/communicate near the limit. Wear so far has been surprisingly good--I got 20 heat cycles out of the first set, and they probably had a few more left in them. Interestingly, they seem to require less negative camber than the NT01s--I was actually preferentially wearing the insides of the tread all around with the RRs. They come in only three sizes so far, one of which is 275/35-18. Here's a link to them for more info: http://www.tirerack.com/tires/tires....odel=Proxes+RR

Thanks for the review. Do you have any lap time deltas between the RR's and nt01's?
Also, can you comment on the grip level throughout their lifespan? ie do they get slower like a Hoosier or faster like an nt01 as they wear? |

Quieter? I love the coo'ing noise from the NT01s.
Sub'd.

Subjectively, the Proxes RR certainly feels faster. I do get the sense that the NT01, aside from the hopefully resolved tread splice issue, is a real sweet spot in the range of R-comp tires. Good grip, relatively cheap, and wear like iron. I think that the improvement in grip and overall track readiness is huge when moving from a street tire like the Michelin Super Sport or even Yoko AD08 or Hankook RS3 to the Nitto NT01, but then it becomes a law of diminishing returns when you move from the NT01 to semi-slicks like the Proxes RR or BFG R1 or Hankook Z214. The incremental improvement gets smaller. Perhaps with the exception of Hoosier R6s, which is why they're called purple crack. I haven't tried the Hoosiers, because I know I'd love them, and my tire budget won't allow me to buy new, expensive tires every 10 heat cycles. In terms of performance during lifespan, I feel that the Proxes RRs stayed pretty consistent during the 20+ heat cycles on the first set.

Love that knobby-tire-on-the-highway sound of the NT01s! It's like a deer whistle on the front of your car, but instead it lets others on the track know to clear the way, you're coming through!

I would argue though that R6's and z214's are only marginally faster than nt01's. I run 1.5 - 2 secs faster on them. The only problem with the Hoosier is that it looses 1 second after the first day so it's not exactly a value proposition tire. Agreed that the nt01 is still the sweet spot in this segment, but it sounds like the RR is also a great alternative for us too. Enjoy them! |

Nice write up. I've been looking into moving to an r-comp (currently running Rs-3s) so this is very helpful. I'll probably go with the NT01, to your point, it's a nice jump from street tires. Plus I kinda feel like I need to earn my way to the RRs, R1s, R6s of the world if you know what I mean. Keep us updated.

It sounds like you are buying a little more dry grip with the RRs and giving up a day or two in treadwear vs the NT01?

You can also run an NT01 in the rain with the tread showing. Just don't try them with standing water.
