Hankook RS2s
Anyone run them yet?
I know of one person that has them and I am hoping to test drive their car at the next event. I am sure my Walmart tires will fail state inspection if I run anymore events with them, and I got them in like January!!!

I'm looking at these as a replacement for the hard to find RT215 Falken, and I, too, would be interested in any feedback from people who know about them.
Thanks.
Thanks.
I didn't get a chance to test the car with the RS2s. I was running on 4 hrs of sleep Sunday so I left before fun runs. But the girl that has the car said she liked the tires a lot compared to her regular all seasons.
Like Georgy Porgy here I am also curious to hear about comparisions between these and RT215/615s.

i purchased a set two weeks ago 205-45-16 from a local tire shop here in Orange county. It took one day for the tires to come in.
Pretty nice tire for price. They feel great....I will see how they handle on the track June 17 @ SOW.
Previous tires were Azenis 205-55-16

Previous tires were Azenis 205-55-16
I went from 195/60/14 Azenis to 215/45/16 RS2's
RS2's dont drop off when they get hot
they're good cold, better hot.
they need a lot of air
they're more progressive at the limits, whereas the azenis were an on-off switch.
tested them in ~65 degree weather, dual-driving 6 runs each, and didn't spray them with water at all. seemed to hold up good, we kept finding time

No point in getting up in the morning, then.
I realise now that I'd found the SCCA link before, but it linked to the front page instead of the thread, so I assumed the link was broken. This time, it still links to the front page, but there has been enough activity in the thread that it was visible on the front page as an active thread, so I was able to find it.
There is lots of interesting information there.
The Hanook need more air pressure than the Falken RT215, but they seem to be deciding that the Hankook need less pressure than they first thought. One autocrosser who went onto a course at 46 psi cold found that his times were not reduced if he went out at 32 psi cold.
The tread's deep but nobody's had a chunking problem that they've reported so far.
In the same size, the Falken seem to put a little more tread on the ground than the Hankook, but no one's time seems to be suffering for it.
A couple of people complained about the RT215 not giving much warning and breaking away quickly when compared to the Hankook. I guess that's good marks for the Hankook, but I never felt that way about the RT215, finding them progressive and giving lots of notice...if they just didn't melt on summer days they'd be fine.
Here are some pictures of the Hankook next to RT215 and the new RT615, for comparison sake. Images are clickable for larger size.

I think I'm with Andy on the lower pressures for the Kook's. Just installed my shaved staggered 225/45/16 & 215/45/16 tires last night and did some heavy scrubbing on local country roads. At 35 psi I didn't experience rollover which I would consider necesitate upping pressures. I had previously recieved independent advice from someone else how suggested pressures in the 33-35 range up front for autocrossing, so the data points are coming in...
I'll be out at Peru this weekend testing, so maybe I come back with a little more knowledge on what the different pressures do for feel and times.

The azenis are hardly on/off.... they slide quite nicely and progressively.

Andy, have you ever tested with the MX vs. 215 in the same relatively scientific manner? I know it's not same day same channel data as what you got from your evo course the other day, but I'd be curious if you in particular feel/are quicker on the 215's than the MX's. If so, one might make the inference that the new tires are similar in potential to the MX and are legit choices with the right setup decisions. I'm getting a sinking feeling that the average price of the hot tire for ST has been knocked up a notch this season and we just don't know it yet, people are saying some pretty flowery, glowing things about the new Advan, for instance.

Yes. Did it last year at an Evo Dial In day near Dallas. We had three national level STS civics there with different setups, and swapped around tires and drivers. I was always faster on Falkens than on Kumhos. Might just have been personal preference, but data is data and I'm not going to fght it.
--Andy
PS: Go look at the SCCAForums thread again. Just posted some new and interesting sizing in on the Hankook.
PPS: Advan Neova is not yet available in good sizing for the "standard" STS car (Civic).

For those that don't spend that much time on other forums..
Pretty much agrees with my impression on the street: sticky, soft sidewall. 205/45R16 size is pretty forgiving of a soft sidewall though.
Not darty, precice enough, very quiet.
They have done fine in rain for me as well.
I haven't touched the limits of the tires yet, except in a straight line forward (and I might not recommend them as a drag tire).
Based on the non-dartyness, soft sidewall, I'd say they'd make a fine track tire. But I have no idea how they'd handle the heat, and probably won't use them in the rain unless I'm stuck in a downpour.
Did some more testing today at the Atwater Tour on the practice course. Course was not as nice (tighter) as the one at Atlanta, but the surface (concrete) was lots grippier. This time up I had the Kooks in 205/40-16 and 215/45-16, and the same RT-615's from before in 205/50-15. The short answer? No difference.
I took five runs on each tire and consistently turned the same times over and over (17.1-17.2). There were two outlier times that showed up on the 215/45-16's, though, of 16.7 and 16.9. Not sure what to make of those. Once again, the Falken felt the best due to the firmer sidewall and responsiveness, but the times did not show it.
I've concluded that the Kooks need to be abused a bit in terms of feedback. The Falken is kinda like a Hoosier in that, once you go over the limit, its hard to get back under it. But the Kooks like to scream in pain as the car runs through a sweeper. They can be run at large slip angles and still reeled back in. Or at least that's what was happening on my fastest runs.
I should be able to do some proper testing on a proper course the week before Wendover. More then...
--Andy
Well, I started off with 42 cold as a total guess when I first started on these tires six weeks ago. Tonight I'm sitting on the Wendover pavement doing skidpad testing and have found that these tires can go lower with very little additional sidewall rollover. I've gone all the way down to 30 psi cold and still get good temps on the pyrometer. I don't have clocks setup tonight, so I can't give a time on it, but I believe the grip level has gone up as the pressure has gone down since the car is a bit more balanced now (was plowing some).
So, just some more data...
--Andy
PS: Note this is on the 205/45-16 size. Haven't had time to play with the 15" ones since it rained a little earlier and postponed some of my activity.
Even more data: Had a chance to do some really good back-to-back testing tonight at Wendover. 13 sets of five laps each on my standard practice course (as used in the Evolution Dial In schools), with a timer running. Five different tire models/sizes. I won't spew all the raw data here, but I did learn that I've been running too much air in the Hankooks. Lower seems to be better. This was true in all three sizes I tested (205/50-15, 205/45-16 & 215/45-16). How low? Depends on your tread depth, surface, etc, but try somewhere in the low to mid 30's for cold pressure and go from there. I tried even lower (cold 28) and it never rolled into the sidewall, but was a tad slower. The tire will not feel as crisp with lower pressures, but it seems to have more ultimate grip. And you can fix the transitional response with more shock.
The kicker of the whole test was that my old pair of Falken RT-215's that I use for rains (5/32nds tread) on 7" wheels were consistently quicker than similar sized Hankooks. Arghhhh!!! And to think that I just sold a pair off of sticker RT-215's....
Oh yeah, and I'm still not any faster on Falken RT-615's compared to Hankooks. Maybe its just me?

More new info from the Great Street Tire Photo Shoot, Wendover 2005 edition:
We stacked up pairs of all the contending STS tires, compared tread and section widths, and took pics. The short answer is that all of the 205/50-15 tires (RT-215, RT-615, Kumho MX, and Hankook Z212) are essentially the same dimensions when mounted on the same wheels. Interestingly, despite Hankook data sheets to the contrary, the 205/50-15 has wider tread than the 205/45-16 Hankook. In fact, the 215/45-16 has the same tread as the 205/50-15, but is taller. We also looked at James Wilson's new Toyo T1-R's that he had in a 225/??-14 size. Looks to have the same tread width as all the 205's and the Kook 215, despite being a 225. But it sure is short!
Bridgette Olson took the pics and will post them.

If it's 215-45-16 vs 205-50-15, that looks about right. Remember that you're looking at the cumulative effect of <u>two</u> tyres stacked up.

You know what, you're right. I took a piece of paper up to the screen as a measuring tape, and the ones on the left are larger diameter than the ones on the right. I had my hopes up because the text in the original SCCAForums post said 215/45-15.
