New Toyo Proxes RR

Plays with cars · Plays with cars's Garage

Anyone know anything about them? Looks like a new tire that will be spec tire for Miata and 944 series. They are a track tire, but wonder how they will do for autocrossing. Similar to the Kuhmo V710 but not as good as Hoosier A6?

This is news to me, where do I find more info on the RR? I tried the R888 on my Boxster racing car and did not like them, so changed to the MPSC for the 2012 season.

If the RR is going to be better than the R888, and cheaper than the MPSC then I might try them for 2013.

when I learned about these I got excited until I went to the website and saw there are only three sizes. nothing even close to what I could use. hopefully Toyo will expand their production on these tires. they look like they will be a real winner for them.

Yes, just did some Google work and discovered that they are at the moment:
.- Not available in the size I run.
.- Made for the US market.
.- Not EU approved only DOT approved.

So at the moment not even close to appropriate for my use

I COULD use this tire on my 88 Carrera for track or autocross. I currently run Nitto NT-01 205/50-15 and 225/45-15 on 15x7 cookie cutters. The Toyo 205/50-15 and 225/50-15 would be a good fit and they are a good price. If they are competitive with Hoosiers and hold up longer I would be trying them out.

The quote below is from Tirerack and indicates that more sizes are to come. They must have made a pretty good deal with NASA. I don't know about Finland though.
=========
"Initial sizes will include: 205/50ZR15, 225/50ZR15, 275/35ZR18

Note: Effective 1/1/2013, the Proxes RR will become the spec tire for NASA Spec Miata, Spec E30 and Spec 944 classes. The Proxes RA1 will remain available as the designated rain tire for the above classes, as well as the spec tire for all other NASA classes in 2013. Additional sizes of Proxes RR will become available in 2013, at which time additional NASA classes will be switched."

Interesting article, but a little thin on the actual performance potential for the tire. Clearly a track and not an autocross tire, but so is the V710 yet it does pretty good on the autocross course.

How about the Hankook Ventus Z214 in the C71 soft compound. Also a bargain compared to the Hoosier or Kuhmo, but gets pretty good reviews on TireRack

Rock solid tires. I ran the C51 compound on my GTS-3 911 in 245/40 and 275/40 17 inch and it was an excellent tire for road course racing. Not quite as quick as the Hoosier but close. The C71 autocross tire will be a nice sticky tire for your A-X use. I'm a big fan of Hankook tires.

I'll second what Kevin said. Ran the C51 compound on a Spec Miata in a 4.5 hour NASA enduro and the tires NEVER went away. Great tire especially for the money.

+1 on Hankook. In time attack they are the tire to have. Their new TD is their NT01 competitor is supposed to be a very quick tire.

So compared to the NT-01 which is a better track tire for DE days?

Toyo RR or NT-01 ?

Then which is better compared to the Hancooks?

Well right now the NT-01 is better because of size availability. You have to remember that this Toyo RR tire was created as a spec tire for NASA. So the sizes are few and far between.

Have yet to gather experience on the Toyo RR since its so new. But I can tell you that the Hankook Z214 C51 or C71 is a faster tire than the NT-01.

The Hankook is a solid tire. I found it communicates very well (you can feel what its doing w/no surprises) and the wear is very good. Life cycle is also good. I got 25 cycles out of my C51s and they were still quick. They still had another race weekend in them but I discarded them in favor of BFG R1-S to have a fresh set of tires to start the season (which I admittedly started VERY late and finished very quickly as well- cooked my fresh engine after only one race weekend)

Thanks for the info.

Kevin, I have been reading your post on your engine demise. That completely sux, I feel badly for you. But you are handling it very well my friend.

I am in a similar situation with my 930 turbo engine. Rebuilding it now due to detonation damage after only 4000 miles or so on a fresh rebuild 2 years ago.

Sorry to digress and get off the original post topic:

Meh, that's life. I'm lucky I have an understanding wife and can afford to do it again. Learning more as a result of the failure, so that's a positive thing? Humpty Dumpty will come back stronger and better as a result of it.........

With respect to the Toyo thing, I suspect their RR will behave like their others (except hopefully not like the dreaded R888) in that they have a great lifespan and are fast to the very end. That's one thing that's irked me about Hoosiers is they just die and there's lots of useable tread left in them. All you can do is treat them to try n keep them alive but they're still not as fast as new.

Kevin and I have a mutual friend who races a Spec944 locally. (Kevin, you know who I'm talking about, he bought my old enclosed trailer). At the last race of the season at Autobahn he had the privilege of trying the new RR in place of the RA1's that have been the spec tire for that class. His comment after one day of racing was that the tires were definitely quicker than the RA1, and didn't seem to get a greasy after 40 min on the track.

So the NT01 is effectively an RA1 that's not quite as fast as an RA1 but lasts longer. And the RR is faster than the RA1, so that would say the RR is pretty darn nice tire. If only it came in sizes for other than a Spec944.
