I hope I am not out of area for asking this question in this thread, as I saw it was a stickied tire thread...


Looking for some of the higher power drag strip guys to chime in. I am in the market finally for some good gripping rears for the quarter mile. I am looking to see what drag radial options I have that are sorta Miata friendly in size. I have 2 sets of wheels I could choose to run them with, either 15x8 et20 TRM C1s, or some 13inch Honda CXs (13x6 I believe?)

The Honda wheels currently have some Goodyear road race slick it looks like on it, 22x7.5x13 I believe.
Any guys running DOT slicks on their Miatas? Any tire info as far as price and popular/proven sizes let me know.

I autox'd on some 275/35 hoosiers with the 15x9 6uls on Sunday in an SSM miata and Oh.... My...... God it was glorious.

The grip was beyond my comprehension. I had no idea what to do with it. It was my first time on hoosiers, 4th time on r-comps, so the learning curve is steep. The car puts down around 220 rwhp, has the atc200 wing, 96 r-package so stock 4.10 torsen, the backend did not come around under throttle, only if you upset the car with bad steering inputs.

I'm co-driving the same car next season, so hopefully I'll get use to them quickly. But it'll also have 100 more hp and a lot more shock


I recommend every track racing miata nut to drive on some 275 hoosiers at least once, its quite amazing.

Shhhhhhhhhhhhhhhhh. LOL we can't have everyone on 275 Hoosiers.

Here is a side by side shot.

On the Right 205mm wide Nitto NT01's on the left 275mm wide Hoosier A6's. Is the difference noticeable?

I think you have to much wing angle.

eunos735

I had just used the car for an Auto X with MUCH lower speeds than a open track. I was attempting to make the wing more effective at speeds of 40-60mph.

Hoosier makes a 245 radial slick that is the right diameter 22.9". R80 and R100compound mounts a 7' to 10" rim per there listing

Yes they are like a highly addictive drug. I wore through one set this year then picked up a co-driver to help me buy another set. Seems like they work out to cost somewhere between $15 and $20 a run. They would last longer I think mounted on 10” or 11” wheels. Luckily I won contingencies for another set for next year.

I also have thought about getting a set in R6 compound for the track. Even though they are gawd awful wide they are still over 2 lbs a piece lighter than 225 Nittos.

I love my RE-11 they have worked great for me even kept wheel spin on my 350whp miata down. Also at $97.00 each cant beat it from sears.

Rather than start a new thread I will ask a question here I think is still relavent.

I am looking at getting a set of 225/45R15 for track work but still need to be road legal. I am in Australia so the selection is extremely limited. I have basically two options available, the Kumho V70A and the Nitto NT01.

Has anyone here tried the Kumho V70A http://www.kumhotireusa.com/Tire.asp...a257ab7&cat=18 and can anyone offer any comparison between them and the NT01? I am basically after best lap time but would like to see 5+ track days from them, both of which should last that long without too much drop off in times I think.

Cheers,

Tim

I’m a little late in answering this but years ago when that tire first came out I had a set. I used them at Thunderhill once and literally blistered them with big chunks of rubber down to the cords flying off destroying them in a single day use don’t know if they changed it since then. Prior to that I used V700 Victoracers and never had that problem I think they were basically the same compound but the tread pattern was different and the casing was definitely different. The Ecsta V700 V70A was allot squirmier and not precise feeling at all but had good grip until they became quickly overheated. The Kumho V710, the one with jut two grooves around it would be really fast on the track if you weren’t doing a very long session they might hold up Ok but they are really more of an autocross tire and they only come in a 225/50/15. They will be faster than a Nitto NT-01 early in there life but have less than ¼ of the life span of a NT-0 even if you took good care not to abuse them too bad.

I've driven two different miata's, both with 15x9 6UL's and RS3's and the R1R's, the R1R's do noticeably better in rain/wet which is nice for a street car in the Northwest.

I remember reading the Toyo R1R's run faster on autocross and for HPDE's compared to the RS3's but tend to overheat easier and are slightly less communicative on the limit. I haven't had the R1R and RS3 on the same car for a track day, so it's hard for me to talk about their performance difference there (different suspension, power, etc). But we're comparing $125 tire against a $100 tire. Both are tread rated 140.

I guess my point is, if you can't find RS3's, pick up the R1R's. The tread looks cool too!

Just my two cents.

Just an FYI but most of the guys posting impressions are running open track. Autox and open track demand different things from a tire.

Also a point I didn't see discussed is hp vs tire width. Emilio recomended in a few threads to stay on a 205 until your in the 140hp range or the aero loss is not worth the width.

Also remember that a 205 is fastest on an 8" rim and a 225 is fastest on a 9".

I think I'm going to go for the 245/40/15's made for the Caterham CSR. I can get them for £140 each which is roughly the same price for 225/45/15 R888's. I've just got to order some 9" wide rims first ...

I'm curious, who figured this out and how was it tested?

lol, read your sig. you're at the common sense part, hopefully soon you'll be @ the wisdom part. and don't be so hard on yourself. not everyone has had a chance to partake in MT.net & emillio's wisdom.

jch13

I'm not being hard on myself?

I've seen 225/45/15 RS3s mounted in 15x9s and they looked very stretched, common sense says that setup is not good. EDIT: in fact, the largest rim width the 225 RS3 is approved for is 8.5in.

I am just curious to know if some organization or person had taken the same Miata, with the same tires, and different sized wheels around the same track and compared times. Or if the conclusion was drawn from anecdotal experiences.

yes, scientific method employed by some of the top miata racers in the country. conclusive beyond a reasonable doubt. but don't believe what we say is true. please mount 225's on 8" wheels so we can embarass you on our 9's. hoosiers and nt-01's have the slightest stretch, nobody's talking about all season's on 9's, don't confuse us with cr.net

jch13

Whoa, don't take it personally, I was just explaining why the "225s on 9in" statement confused me given my experience. Now that you say that some people who really know what they're doing figured it out, I am convinced.

I never said I didn't believe you, I never talked about all-seasons, I never said I knew better. I'm just asking a few questions, that's all.
