R888s are good in the wet, but RA-1s are better IMO. But....R888 (when newer) are much better in the dry than full tread RA-1s.

SO the Maxxis Victra RC-1 is now available. I am going to try these when my current NT-01's wear out.

$140 bones for a 205/50?

Please let me know how these compare to a NT-01. I am highly intrigued. From the looks of it, they would be a +7 tire with the NT-01 for NASA, but early testing seems to indicate they will be a tad faster.

I ran the R1Rs on my GR (275/40R17) for three track sessions this spring. My car puts down ~380whp and more torque as a ball-park for power along with us all knowing the GR is not light. I have TiC coilovers and 8/7k springs and some other basic suspension goodies running -2.7F, -2.2R camber.

I think I can get maybe another 5 heat cycles out them. One track day was rather damp, the other two were bone dry (one was close to 200 miles of lapping at ORP). The tires handled well, best tire yet. They were predicable and the degree to which they got sloppy was still rather linear and they stayed driveable throughout a session. I will say that if the sessions were 15 min longer the tires would have started to feel a little too squirmy. Maybe that is normal, I don't know.

Likely I will pick up another set and use as a daily tires that can second for a wet tire in OEM size and shoot for something like the NT-01 for the next track set and compare.

I got a new set of 275/35/r18's and have autox 2 events, (pretty sticky here although with a 2 driver setup they got greasy, and just missed my first rack day due to stripped brembo caliper bolts. Have another track event coming on 31st....once my Ap BBK setup arrives this week, I should be ready to actually try these on track! I had previously run star specs in a 245 width and really liked those, was close to getting the new version, but opted to try a ,more track oriented tire.

My buddy and I got some to run an old sentra in enduro but the car broke on 2nd lap. He ran them in 2 sprint races and was running 2 seconds off of a6 at road Atlanta which ain't too bad. His car isway lighter and fwd and on 205/50/15s though. Curious how yours do. What size did you get?

255/40-17. I'm coming from a set of NT-01's in the same size, so we'll see how they compare. I would expect them to offer a little more grip, but we'll see.

I've run all those tires back to back in all sorts of crazy conditions. Road racing in driving rain on full depth RA1's can be very sketchy. In that weather you can be flat out with the Hoosier H20's and have a lot of confidence.

The compound of the RA1 has changed in the last 2 years. It's not the tire it used to be. Racers are getting less time out of a shaved set for dry running.

The NT01 is still a fantastic tire for dry running and durability. Surprisingly fast. I'm buying 2 sets for a 13hr race shortly and it will be interested to see how many we use and if we should have ordered more! In the cold weather i won't trust the RA1 full depth in the wet. I'll have hoosier H20's on hand just in case. The difference between the RA1 and H20 is that one tire is fun in the rain and the other can be nerve racking. And I love driving in the rain.

When I was daily driving to TT's i had the all around street tires on the car and fast dry's in the trunk. When I got the trailer and all the garbage... Practice dry's, race dry's, wets all mounted and ready to go.

I'd love to buy some Hoosier wets but I haven't had a rain race in 2 years. What's the shelf life like on those things if they just sit in bags?

Not long. 1 -2 years post manufacture date. They are the softest tires you can buy and they do go hard over time. When they're hard - they're f*ed. Never buy old H20's or "wets". They can be bought full depth 3 yrs old for $300 and it's like throwing money away. They are garbage after they harden up. The crazy thing is that they feel soft after a few years to someone who has never been around them. I new set is like bubble gum. An old set of rains feels like a new set of R6's.

I'm in New England and it rains quite a bit. I have felt they are so expensive that I've tried to save them... that was a mistake. Smoke em if you got em. They die quickly. Just enjoy them.

General question for some of you tire experts. This season I picked up some sets of rubber with the intention of running a full season with Narra..life happened..have only been able to run one event so far this season

I now have a couple sets of slicks, Hoosier r6's 245/35/18, that I had intended to use up this season but that does not look like that will be the case.

My question is will these tires loose any noticeable grip from sitting a few more months in my basement, till I get a chance to mount them up next season on track? Should they be in bags or anything else for proper storage?

I purchased at tirerack back in May of this year and had them heat cycled as well and I'm worried that I am potentially degrading these tires for competitive use next season by leaving them sit? Is this a valid concern or will I be perfectly fine with no noticeable effects in tire performance?

Yes I am aware that tires spend many months sitting on shelves in warehouse's..this however is my first time owning real softer compound slicks and just want to be safe rather than sorry.

Also on the same topic. I currently have Pirelli Trofeo R's mounted that I ran half the one event on and they have been sitting mounted on the car since, while its in the shop. These are a treadware 40 or 60 I believe and also pretty soft. Are these tire's at risk of flat spotting from sitting too long while mounted to the car or will that work out in the next heat cycle? They have been sitting since mid june but I plan to run these soon at Summit, VIR, and Sebring to finish out my season.

I apologize for my lack of track tire knowledge in advanced. Just trying to gain some useful knowledge and insight on how softer compound tires react to different storage conditions. This is my first season on dedicated track tires. I was running re-11's and star specs before these which I never thought twice about storing, flatspotting, etc. I'm sure I am just being overly worried and my tires are perfectly good to run! Trying to get into good habits now while I'm still new to r-comps. Thanks

R6s will be fine. Put them in bags. Pirellis will get lumpy but will go away in one lap

Ive heard through back channels that they are comparable to the Toyo RR and a few tenths slower than an R6 on a car optimized for running the RR.

Oh, and they are a +10 tire with NASA.

Well, I'm not thrilled with them, but they did OK. They definitely need to run lower cold pressures, as I struggled to keep them below 40 PSI hot, but once I got them down to about 38 hot they had good grip. Honestly, they didn't feel much better than NT-01s, but that may just be a matter and running more laps with them at the optimum pressure/temp. I'll run them again on November, so we'll see how they do in the cooler temps.

They definitely shouldn't be a plus 10 just like the bfg r1s shouldn't be plus 17 or whatever crazy number it is

Oh come on the R1/R1S is stupid wide. Have you seen the tread measurements in comparison to what they say on the sidewall!?

Get outta here. It's one of those deals where some are wide some are not. I run 245/40/17 and the r1 and r1s match up perfect to r6 and a6. It sucks when a mfg makes one cheater size and all of the tires get punished. I sent pics to NASA and was ignored

Ironically, a friend of mine just used those tires on his 07 WRX wagon at Road Atlanta this past weekend. He liked them over his NT-01s, if I remember his FB post right.

You and the rest of the world. The 245 is assessed as a 275 per their measurements. The tire is quicker and there's a reason. Hoosier has the corner on the compound so the only way to go from there is sidewall and tread size

I think the a6 is a tick faster for me (sticker vs sticker). Very close though. Just butt dyno though because I've never run sticker a6 and sticker r1s at the same track

I'm curious what the story is on the Hankook Z221 TD. That link makes it sound like there's a full range of sizes available, and based on a little searching/reading online it appears to quite popular in Japan/Australia/NZ. It's been around for a couple years already, but for some reason it seems to be only be available in a few sizes here (Discount Tire Direct has 1 size in the Hard compound and 3 sizes in the Soft). I know there have always been track day type tires available overseas that weren't available here, but this is a case of a tire that is available here, but only partially. Kinda strange.
