I can one up that post.

275/35/15 DOT Hooser versus 23.5X11R16 Radial Slick Hoosier. Now Im working out building a first gen car around using these.

 

Looking forward to seeing the result

 

In the series I run we are only allowed to use road legal tires. Here is what I run:

Toyo R888s - warmed up after 2 croners, but overheats in lap 5 and melts in lap 9, no matter what settings I (we) have tried. Excellent in rain. Commonly used as rain tires in my series and in the dry by the low budgeted drivers.

Kumho V70A. Frikkin assume. You can beat on them, abuse them, slip and slide and they keep asking for more. Lots of grip. Wears out fast, so the price per lap is pretty high. Sucks(!) in rain.

Yokohama A048. Has 85% of the Kumhos grip, but wears a lot better. I have a set to practise on, since they are a lot cheaper per lap then the Kumhos. Works reasonablt well in rain.

 

Can you guys get BFGoodrich R1s over there?

They should have most of the grip of the V70 but much better life. What about other euro only tires like the AVON or some Michelin?

 

I'm going to be running falken ziex 912 tomorrow at big willow . Think I will have any problems?

 

Nt 01 225/45/15 Nittos, seem to last longer then the RA1's I was using earlier on. John

 

First post here-
I ran MPSCups on my 996TT and hated them and wore out fast. Currently have V12 Hankooks and love them plus half the price. Will me doing a few Laguna dates in March. On here because I'm contemplating getting a Miata SC built by TC Design.

 

Good to know! Thanks

 

I really enjoy my nt-01's and they are really wearing well. They lack the ultimate grip of my out of date victoracers, but they sure are predictable. And they don't get stupid on rain, which is nice. I really want to get some times this year and compare them to my star spec dailys. My 0.02.

 

someone was talking about the A6, hoosers autocross tires. if you can pay the coin they are sick sick tires. the grip is limitless but the burn up mighty fast when driven at the limit on a road race track.

 

Let's not spread the purple crack kool-aid too hard. Limitless grip? The A6 will give more outright grip than an R6 or R1 but it certainly isn't limitless.

Both Goodyear and BFG have recenetly released "autocross" compounds of their popular D.O.T R-compound tires. Both of those tires should be very similar to the A6 as far as ultimate grip and tire life. I only have experience with the BFG R1 "S", so I can't comment on the A6 or the Goodyear.

 

Yay! 1000th post...

GEH

 

well obviously there is a limit, so I was exaggerating. I've driven and rode in plenty of very fast road race cars and Ive been extremely impressed with the grip of the A6. that tire will let you drive around other cars in a DE full of seasoned drivers in fast cars like they are parked. the down side is that when used in road race conditions most people change em out in about 1 hour. the tire will continue to grip for some time I'm sure but obviously my point that it is not a tire for casual track events. If I ever got serious about TT I would get that tire. but that wont happen.

I'm really more into the endurance because running for a hour straight or however long it takes the car to run out of fuel and keeping times within a couple seconds makes me happy, and feel like I've got a car that is pretty set up, which is what I hope to do with my miata.

 

For sure, if you are in a car on A6s driving in a DE event with a bunch of cars on street tires, it will feel like you have the ZOMG PURPLE CRACK.

Have you ever driven a car with the BFG R1S or Goodyears Autox tire, or Kuhmos autox tire, or Hankooks autox tire? Or non-DOT slicks from Goodyear or Hoosier? Yes the A6 is a very grippy tire, but it is not the only one. There are other similar tires out there.

For sure, most of the competitive guys in NASA TT who are winning tire contingencies are running A6. For sure they are running the A6 because hoosier is the only one paying contingency for NASA TT.

At the runoffs, in classes where a DOT r-compound is required, lots of people run the "autox" compound because they can last a 45 minute race and they are faster. For sure, these same guys are using a new set of A6s (or other autox compound) for every session. I used approx. $4000 worth of autox compound tires in 5 sessions at the Runoffs. For sure, this is not the tire for the average DE guy who is looking for longevity.

I think it's well proven on this forum that a tire like the NT01 is the best balance of cost vs. grip vs. longevity for the DE driver. Emilio has also shown the NT01 may be the best tire for the endurance racer also (at least in a miata). For sure we've had very good results with the standard BFG R1 in our endurance racing, going over 4 hours on the front tires in a FWD car and 8+ hours on the rear tires.

P.S. Practicing my pro race car driver method to start a sentance...

 

no one runs a street tire or autocross tire in the DEs I do so my experience with auto cross tires on a road race track is limited to the A6 so I cant compare to other models. I ordered a set of NT-01 for the miata because, like you said, they seem to a good tire at a cheap price. I'm not doing the hooser thing at least until I get the car dialed and know it is reliable on the track

 

On some 225 RS3s right now

 

Have you driven both the R1-S and the R1 or just the R1-S? Contemplating between the two and wondering about the characteristics of them.

 

Yes, I have a decent amount of experience with the R1, and last year at the Runoffs ran a couple of sets of the R1-S. The difference between the two compounds is similar to the R6-A6 relationship. The R1-S gets up to temp. more quickly and has more ultimate grip, however the tire wears more quickly. Unfortunately, my only experience with the R1-S is on an SSB Civic Si which is very, very hard on it's front tires. I don't know how my experience will translate to your car but assume that the R1-S will have similar life as an A6.

Ultimately, I think the R1-S has more outright grip than an A6 but I don't have as much experience with Hoosiers. I will say that one of my competitors in an SSB Mustang tried Goodyears, Hoosier A6s and the BFG R1-S during the runoffs and he started the race on the BFGs...

Is this a track car, TT car, or a race car?

 

Car is DD/track NC in Texas heat...how well did the s hold up to the heat throughout a session compared to the R1, do they get greasy, do they talk much at the limit of grip, and when they do let go is it progressive and easy to manage?

 

Unfortunately, it's hard for me to answer this question since my only experience with them is at Road America, in Wisconsin, in September. It would be foolish for me to try to tell you how they are going to be in Texas in July...

I don't remember the R1-S ever getting "greasy" during any of my sessions, but like I said it was September in Wisconsin. Also, my SSB Civic race car is a weird animal, unlike most other proper track/race cars. It has a completely stock suspension, we have to do weird things with tire pressures and alignment to get fast lap times. The car is really hard on front tires, especially the front left at Road America.

For a track car where maybe ultimate lap time is not the #1 priority I don't know if the R1-S is the tire for you. You'd be sacrificing a lot of tire life compared to the R1 for what reason? Does it matter to you to get the last 1 second of lap time? Are you doing any autocrossing?

I think if I had an NC track car I would try to get MX-5 cup take offs. I'm pretty sure they are a standard BFG R1, sized 225/45/17. There's got to be a few MX-5 cup teams out there selling their take-offs for cheap...
