Maxxis RC-1: who knows anything about it?

I'm hoping for something cheap and long lasting, though I doubt it will out-do the NT-01.

Those look good. I hope they are at a low price point.

I have been highly disappointed with my Maxxis mountain bike tires. First the front one and now the back one have both done this. And I have a friend who's Maxxis tire did the same thing on a hut to hut trip from Colorado to Moab. Hopefully their automotive tires will have better quality.

I know their razor is very popular in the atv crowd, I had two on mine and they were awesome.

Always had good luck with them on my karts

Out do the NT-01 in what. Out right maximum grip? Longevity? Grip vs. Longevity vs. Price?

This is the first I've heard of this tire.

I wish Federal would get more serious about the 595 RS-R in the U.S. :(

Any of the above, at a lower price. I doubt anything will shake the NT-01 from it's throne, but I don't know much about tire chemistry and how it evolves from year to year.

Everything that I've ever had contact with that was made by Maxxis sucked most hard. They're a Chinese scooter tire company that has tried to branch out. Expect results as such.

What throne do you speak of? The best combination of dry grip, longevity, and cost for a guy doing track days?

The Hoosier R6, BFG R1 and the Goodyear Eagle RS all have better dry grip (I might even say much better) but of course you pay for it. I'm not sure about BFG R1s on a miata but we get very good longevity out of the BFGs we use. I would be willing to bet the BFG R1 could give the NT-01 a run for it's money even for a track day guy. You would get better dry grip, almost as good of longevity at a higher price. Unfortunately BFG doesn't make a 225/45/15. I know they've looked into, but haven't heard if it will go to mass production or not.

If I were running a turbo miata at track days I would be using Continental Grand AM take offs. You can get them for half the price of new NT-01s, and they should last just as long (they are an endurance compound) with as good of grip. They're the right size (225/45/15) and it looks like RSR is going to continue running Minis in Grand AM so there should be a decent supply of them going forward.

My two cents

There is no BFG that fits our 9" wheels, hence why the NT-01 is The Lord. The only other tires I could run are C71s, R6, or GAC. Unfortunately, NASA adjusted some point rules and I am maxed in points in TTB at 205whp.

This sounds like a really good option. Thanks for the heads up.

R6 is maybe .2-.4 faster for about 8 laps. Then they fall off and are slower. Net life less than half of NT01

R1 about 1 sec faster for about 20 minutes. Then they fall off and are about the same until they die, which happens in about 30% the time of an NT01

Eagle RS - more than 1 sec faster, great heat cycle life but still as less than 50% as long as NT01's. 50% more expensive

If the competition is who can run all day Saturday and Sunday on one set and have the fastest time last session Sunday, NT01's will won every other tire on the market.

I've done back to back with R6's, R1's and NT01's but not RS's. Not guesses or estimates but personal experience.

FWIW, we just flat destroyed the field at T25 on our NT01's wit the combination of speed and tire life. Almost no one ran them. AMG wo chased us the whole time, would go through 3 RF tires for our one. The next car back was the Hooverspeed Miata on R6's. We were 2s faster with the same power and weight and change tires half as often.

In short there is a very real reason why the NT01 has become the defacto standard for HPDE.

If the Nitto is so much better, which I believe you one, why does everyone pretend that R6s are so much better?

Taiwan. They have done well in karts and rock crawling. They have not done well in the US passenger car market. I don't expect that to change, even if they had an amazing tire, they don't have a very good distribution system.

Hoosier makes great qualifying tires.

Most HPDE drivers and club racers never really learn how to thoroughly develop and tune a car. Many use settings from someone else, based on hearsay, superstition and what somebody used successfully in a car nothing like theirs. R6's are fast right out of the box then they fade. Most drivers will recognize the grip of stickers but not recognize tires falling off. Hoosiers have a sort of mystique as magic tires. I think most people don't really know how much difference there is between sticker A6 and R6's.

I have personally witnessed drivers test NT01's, go faster then switch back to R6's for the contingency money.

Short version: a lot of people are mistaken.

A6's are the best bet for sprint races too. They're no faster than anything else by the 30 minute mark but by then you already have a fat gap because they were 2 sec a lap faster for the first few laps and you ran away.

The cool thing is you don't need to scuff A6's. Mount them up. One slow lap through the pits to get rid of the mold release then line up for qual.

the guy that was in charge of NT01 US distribution ~5 years back (when NT01 became popular) is the person in charge of Maxxis RC-1.

RC-1 has been tested numerously in SOCAL HPDE scene. it is a pretty good tire from what I've heard, from people I trust. another r-comp choice is always a good thing imo.

Thanks for the help, California bros.

And in some 15s... I was Impressed with how your Federals handled on your car :skid:


This is exactly what I use from RSR, but to be 'competetive' in TT (if Nasa ever comes to Barber) I'll have to go with Hoosiers A6s, maybe win some other Hoosiers? - doubtful

And that being said - it's proably what I would do too... (previous retard statement withdrawn)

I'm especially pissed about the competition is running a 255 R6 that's actually 280mm wide, they set a ton of bullshit records that will never fall, then tell the rest of the field "sorry" and let them keep the 14-tires they won last season and let the records stand. In a tight pack of my Miata, E90s, S197's, all with good drivers maxed on points, we were always 4-8 seconds behind the leader using the cheater 255 that's wide on a 10" wheel.

That's good to hear. They had one moderately good tire in the past, you could only get at citytire, and was only in a few select sizes.

They also kept teasing with the ZR9 195/50/15 track compound for years that to my knowledge they had one carcass that never left the corporate office in Atlanta.

Not sure if you've looked at the 2012 rules yet, but this was added in there...

I'm surprised you only get ~30% of the life from R1s. We've had much better luck with R1's but that's with FWD mac-strut cars with 17" wheels/tires. We find the R1's to have very good longevity, whether it be in enduro's or sprint racing. I don't have a lot of data but in my experience we're getting much more like 80ish percent of the life of an NT01 and it's at least 0.5s faster over the whole life. 1-2s faster for the first couple heat cycles.

On our older civics and integras we find the 205/50/15 R1 to be faster than the 225 R6, 225 GAC and 225 NT01s. I'm suprised it's not the same case for miatas...Our K24 powered '99 civic si was faster on 205 bfgs than 225 r6s, that was on 15x8 wheels. Faster by over a second...

You can't stretch a 205 onto a 9" wheel? In my experience the BFGs are the biggest PITA tires to mount so I could see a 205 on an 9" being a problem. 205 on an 8" wheel is doable. I said this before, I know BFG has looked at producing a 225/45/15 R1 but I haven't heard if they were going to be able to do it or not. I hope they do.

I don't want to sound like a BFG dealer or something, but our race team has been very successful with them and I'm surprised more miata guys don't run them.

P.S. MotoIQ guys tried the 225/45/15 Eagle RS and not only is the tire actually 235mm wide but they also like the tire very much. Maybe this would be a better option for you guys running TT, as you could get a 235 tire for the price of a 225 one.

I assume this is the same guy you were talking about in the NASA Texas TT thread? I still don't understand how this guy fits into B. If what you say is true, even giving this guy all the benefit of doubt in the world he still doesn't stay in B.

Try #2:

PTC** @ 3415

Points:
** = 14
255 R6 = 10
3300lbs = 8
Intake = 1
Swaybar = 2
Catback = 2
AST = 3
Brakes = 2

Total = 42 (TTA)

So if the guy is actually running at 3300lbs comp. weight he's in A. Even if he's running a stock cat, stock springs with his ASTs, running the 255 hoosier, taking 0 points for his tune, stock pullies etc, he's still in A
I'd like to see this guys TT classification sheet.

If he's actually running closer to 3400lbs comp. wt then he might be able to stay in B.

Either way, I'd like to see the guys sheet. You said he ran at nationals this year? I remember a silver/gray E46 in TTB paddocked near us, I wonder if that was him.

PS SORRY FOR GETTING WAY OFF TOPIC and double posting

Not to mention he was on a cobb tune in '10 and was @ ~ 300whp. For 2011 he had an epic tune and was claiming it made 25-30whp more after fixing his var. Intake or something. Might not have been peak whp, but it was enough that he wouldnt mention the numbers or show numbers on his dyno plots when posting on bmw forums. "just in case"

I saw it make 335whp on a Dynojet.

I'm aware, but that doesn't change the record sheet. Anyone who's ever run Hallett knows that a legal Miata like mine at 210whp (last year) with no aero will never, ever run a 1:25.5 there. A 1:27.00 is feasible, and blindingly faster, but not a 25, there is just no way in an TTB car. When the TTB cars break the TTA records, something is wrong.

Something else that's interesting in my dyno reclass is that I still cannot class my car in TTA(no **), it goes straight to TTS. My options are to run 200whp in the cars current form for TTB, add aero for TTA, or run 201-275whp and run TTS

So, what, his record shouldn't stand?

Looks like this guy finished 4th at the 2011 championships almost 2s off the fastest time (and about 1.5s slower than I ran in a PTB car).

1. Maybe he had to "uncheat" his a car a little bit to pass tech (tech @ Nationals...LOLZ) and not get bumped to A.

2. Maybe he wasn't familiar with Mid Ohio and that's why he didn't mop up.

3. Maybe his car is legit (LOLZ) and is somewhat competitive nationally. Which means, unfortunately, maybe you and your car aren't competitive nationally.

I wonder if he got dyno'd at Nationals. My car did 265whp on the dyno at Nationals and has to run around 3150 lbs, so we're no where near the HP/WT limit of B.

My guess is a bit of both 1 and 2. I'm gussing he did have to uncheat his car a bit to pass tech and not over-dyno at nationals. And I'm willing to bet he doesn't know Mid Ohio well and that probably hurt him too. All said, your "buddy" was 0.7s slower than the TTC national champ, who happened to be in an E36 M3. Actually his best time would have barely put him on the podium in TTC...

...and to think, those were old, bald and cord showing....I just put a fresh set on and it's even more point-and-shoot now ;)

All I know is rumor that his car had some problems in tech. We also know that car will be slower with 1.5" less tire this year. It's very simple to me, a 11.7lb/1hp Miata on 225s is not an even match against a 10hp/1lb car on (virtual) 275s, regardless of how short or light the Miata may be.

Frankly, the guy is my friend, and I believe the car is legal, but the tire he did so well on last year is no longer legal, and this adjustment should have been enforced mid year in 2011. The other thing that bothers me are the HP numbers for my car, I don't understand why they insist upon an 11.9:1 ratio, that's a TTC number. If you take half a second away from him for the skinny tire this year, give me half a second in manliness, and lets say figuratively I recieved a hp/lb ratio closer to the TTB limit than the TTC limit, I might get another .5 second and suddenly I'm in contention for a win at the tracks I know. Unfortunately my car is getting slower so none of this will happen. That's a 7psi number, maybe I'll just kill TT and go back to running DE and only care about TXMC.

I we're still talking Maxxis tires, I've used some but not the model you're talking about. My wife has some on her car, MAV-1 I think 205/50/15 on a 03 protege. They were $70 each and are grippy enough she's broken every sway bar link since getting them, they seem to be lasting too.

PS disregard anything I said about using BFG R1s if you run in NASA PT or TT as they have been nerf'd by NASA. As of 2012 they are a +13 tire, which now handicaps the tire pretty badly. Not to say they're not a better tire than the R6s or other +10 tire, but I don't know if they are 3 points better. The standard R1 certainly isn't as fast as the A6 (another +13 tire) over a single TT lap.

Any updates on this tire? Saw a GRM ad for 225/45-15, read through thread and curious about a little more track data in the last year plus.

I bought a set to try/test out. nearly half the cost of a brand new set of hoosiers, and roughly $50-75 less than a set of NT01's depending on where you look in the same sizes, respectively.

the RC-1 is definitely heavier than a R6. not sure by how much as my scale is broken, but its noticeable. and yes, maxxis ships them in boxes.

fwiw.... R6 205-50 (left) vs RC1 205-50 (right)

imo, really hope NASA decreases the +10 tire penalty at some point.

Are both bare tire in that pic, or one/both on a wheel? What size wheel(s) if so?

Thanks for posting this. How much are these poverty tires?

These are unmounted sitting on the floor.

Currently available only on the maxxis rc1 site at a price of 140 and some change shipped.

I did like how they're shipped in a box to avoid scrapes and punctures

We'll be supplying one of the test cars to NASA for tire testing in the next few months. A few different cars I think, their driver(s). From there it's up to NASA to decide what points value to assign. Based on my preliminary runs, it will likely end up a 7pt tire like an NT01, but that's just a guess.

Interesting that they are noticeably narrower and heavier.

It's not that the 205/50 RC1 is narrow - it's that the 205/50 R6/SM6 is freaky wide.

Yea.
Like mount it on a 9" 6ul and it doesn't look weird, wide.

Excellent, next thing I was going to ask is if they would work well on a 9"
