Anyone Tested The New Toyo RR's?....
Searched but didn't find anything. I know Spec Boxster's are using them this year, we (POC) have another spec class that's considering them. We'd like to hear of any comparisons to RA1's or R888's....
Thanks in advance....

Spent two days last week at Chuckwalla testing RR's to RA-1's on an under 2:00 2.5 liter 914/6 GT. The RR's are very good.

John my thoughts on the R888, RR, RA1.
R888 = not very good tire. Heat cycles out very early in life of the tire. Know a lot of guys that won't touch them.
RA1 = Not the same RA1 that you could run to the cords and still be fast like the Nitto NT01, but good tire especially in the rain
RR = on a track like chuckwalla they are 3-4 seconds a lap faster, maybe 2 seconds at Willow Springs or AAA. Doesn't last as long as RA1 and you can't flip them or rotate them like the RA1. They had a lot of tread separation early on until the mounting issues were explained and understood. Basically they can only be run on one corner of the car or cross mounted. Need more negative camber as they are more like a hoosier than a traditional toyo. Tire budgets need to be hiked up as a result as compared to the spec RA1 tires for the above stated reasons. Works and wears well on a light car (944 spec) not as much on a heavier car
Hope that helps

RR's like camber.
Typically ran 2.75 on the fronts of the 944 SP1, now try to get as much as I can. (over 3)
Much quicker than the RA1's (888's were a bad memory for SP1) I typically see 16-18 cycles before they are corded. My fastest laps were just before they corded at TA this year. I have worn them out before they felt heat cycled out on every set I've run.

All the 944specs made the switch mid last year, and immediately shifted the whole pack up 2 seconds across the board. Still not as fast as a R6, but given the wear probably faster average over the life of the tire....

Are they gonna make any sizes other than 275s for 18s??? Us RS guys would like some 245s and some 325s/335s.

I'll add, only as a footnote, that I don't think the NT01 has the old incremental improvement right up to the end characteristic any more, either. I think Toyo changed something in the manufacturing process when they started up the R888 and -- since bringing the RA1 back -- haven't fully gone back to the old process for either the RA1 or the NT01. It's pure speculation on my part, but I've been running NT01s on the same car for a long time.

So, are they at their best on the first heat cycle like R6s or do they get better up to a point. How many heat cycles do you get while they are competitive.
