Had Khumo's in the past but had big problems with tread cracks all the way across the face.Ok for autocross but not for a high speed road course.great grip though and handled abuse quite well!

Gearhead, are you referring to V710s or V700s?

OK. I corded a set of V710s I got used from a friend last weekend on the E30. They were of course slippery, but wore out without issues.

888s practically REQUIRE shaving & heat cycling before hard use
Quote:
As you note, they're bringing back the RA-1s but for what (I think) is the wrong reason. The 888s do not last nearly as long as the RA-1s did plus they're a bit more sensitive to being shaved and heat cycled properly before use. Granted, this is coming from a Spec Miata racer (gotta love 2400# w/driver ) and not the one who drives the M on track (that's the wife's job - see, I get to race a Miata ) but I learned a lot about reading the 888s and how they wear. A vast majority of the guys complaining about them were pointing to a longevity issue (they do have a shorter life than the RA-1s which I think made people expect the same from the 888s) and significant tearing even when shaved (2/32 for the "fast" guys). Proper care & feeding needs to start before they're put on the car & goes a long way towards decent life. Best suggestion I can make for a new set would be the following: Shave to 4/32 (on a heavy car you wouldn't want the super-tall tread blocks - too easy to shear/tear) Do an easy 20 minute session on-track (maybe 7/10ths?) Swap them for another set and don't touch until day 2 Day 2 comes around (shave, heat-cycle, 24 hour "cure") and you should have a fine set of track tires. Anyway - have fun out there and be safe!

After 3 days on my Nitto NT05's,I have say I am fairly happy with them.They are wearing reasonably well with good feedback and falloff fairly slowly and are noisy as hell at the limit so they are easy to drive on.They do not have the grip of a Hoosier or RA1 but they are fairly cheap so they are a good choice for lapping.

The 888s would appear to have a soft compound compared to the RA1s but perhaps there's something about driving style when comparing how to hustle a Miata vs. the M3. I know you pretty-much have to have a fairly high, we'll call it "rotational velocity" , in the Miata to get a fast lap which would put higher lateral loads on the blocks vs. a less sliding approach in the M. *shrug* To each their own I guess but I wouldn't feel comfortable with the M on full-tread RA1s. They're good in the rain on the Miata but I could see them not feeling 100% planted (block squirm) when used on the M. Back to the subject of this sticky thread though: We're not running R-comps (yet) but did upgrade to RE-11s. Those have been good so far but I think I need to play with the front pressures some more as there was a bit of roll-over from 2 days at the Glen. These are stock sized 19" replacements too BTW...no 18s here. L8R, Brandon |

I am trying to wean myself of R compounds to try to reduce my tire costs,but I do have 8 Continential Series slicks with one heat cycle to burn through before needing more tires for lapping.So far the NT05's look like a good choice for my somewhat aggresive style Last edited by Gearhead999s; 09-01-2010 at 02:41 PM.. |

BTW, there are two versions of the R888: one with reinforced sidewalls (that's what I have), and one without.

rldzhao, have you mounted the cups yet? I think I may go with a set of these next since NT01s are back ordered all over the country. I was set on Hoosier R6s for a while, but I like having the ability to just leave the track wheel/tire combo on the car and use my other car when its raining heavily. I'm thinking 265 (F w/18x9.5) and 285 (R w/18x10).
Would love to keep 275s up front, but its hard to find a DOT tire in both 275 and 285. If anyone has any suggestions on some tires that fit these sizes, please let me knows. Question, would I have any problems running a set of new 285 Cups rear and used, but not completely done sets of 275 NT01s up front? My rears are damn near cooked and I fear I'll need some new ones before my next track day.

Having said that, the overheating was manageable and I haven't experienced any abnormal wear issue. I think the tires have at least two more events in them.

I am still trying to use up my AD08. They seem to last forever... 5 track days so far and not even half worn. |

I have used my R888s for 4 lapping day events now and so far so good. My last tire was Kumho Ecsta XS and the 888s are so much better. This is the first R compound tire for me and I'm pleased so far. Probably will try NT01s for my next set.

Do you guys think there will be a significant difference from ad08 vs 888 on the track? I know r compounds are way better than the stock ps2 but against a really good extreme performance summer tire like ad08??
