Poll: Daily tires that I'll use to AutoX. Kumhos or Hankooks?
Dang, can't make up my mind. People are saying the Hankooks are faster but are they worth the extra money? Are they really faster than the Kumho MX's? Hmmm... :confused: if not mistaken the Kumho MX's took Nationals a few years back.

Wheel Size is [b]18 x 7.5[/b] / Tire size I've been running is [b]225/40-18[/b]

Ill stand by the MX tires any day. Got to use them a couple times autocrossing, and much love to them. Very sticky, but suck in the rain. Not sure how the hankooks compare, but I would hope khumo carries a better name in the tire industry too...

had alot of problems with the mx... sticky, but bad in the rain in washington... plus the tread wore out QUICK! got into my first accident in kumho's...

Get the MX or Azeni. Kooks suck for Auto X. They are okay for a daily driver.
Scott Farmer 11-04-2005 07:37 AM

Not to be a dissenter, Marcus, but I actually like my Hankooks. They're not quite as good as the RE070s, but in 245 width, you can't beat them for the money. Plus, they are amazing in the rain.

They take a bit of a learning curve on the autocross tracks.. but make a dandy daily driver. Quiet, comfortable and good in the rain.

Well I am stuck with this wheel size, at least for awhile. The wheels are 5Zigen, initially went with them for track days (non-AutoX). They weigh in at 17lbs and were about $230 each. When I purchased them they only had them in 18x7.5 but now have them in 18x8 and I think 18x8.5. Coming from a road racing background I figured they would work really nice for track days. Now I could invest in some wheels but honestly it wouldn't be till at least January or after the Holidays. I wanted to AutoX before then but if it's worth it to wait I will. I could see if I could grab some stock wheels cheap. So now not only am I stumped on which tire, now which tire, new wheels, wheel size, which specific race tire and how the heck I'm gonna get the cash :lol:. Thanks guys for the confusion, haha.

Guru ;)

P.S. Well my tires are way bald and I need to order some tires today so I can have them here early next week regardless.

I ran my WRX wagon this year with 245/40/17 Kumho MX's and 235/40/17 Hancook R2 Z212's, so I feel I can make a fairly good comparison. Hands down, no comparison, wet, dry, daily driver, the Hancooks were significantly better.

Nah, I still like the Azeni better. At first I thought the kooks would work, but I really do not like them. Maybe it's my setup or because I am running them full tread. I can't get any confidence in them.

Well you are making a mistake. Not using shaved tires for autox and trying to get the best performance out of them.

PKer 11-04-2005 02:21 PM

Count me as one of the Kook converts. Although I will likely still try the Azenis 615 if they ever come out with 235/40-17.
I wish tire shaving was cheaper, for me it would be a luxury reserved for Nationals.
Hotrodguru 11-04-2005 02:32 PM

I would just like to say that Gary Bailey (Asst. Manager) at Discount Tire rocks! Had to get a flat fixed and figured I would ask about pricing on the Hankook RS2's before I ordered from Edge Racing. He was showing them for I think $158 or so. I asked if he would match the online price of Edge Racing of $128 and he didn't hesitate. Not only matched but he'll have them at the store AM tomorrow and installed price minus tax was $558. Thanks for the advice guys and will post an update since I think I'll go ahead and AutoX this weekend now.

P.S. If anyone's in Houston. Gary's at the Discount on Stella Link, 713.432.0014 and said he would hook anyone up.

I ran Kuhmos in my last Auto-X, had good runs. Tires got a little buttery when they heated up but as long as you have a little driving experience will be no problem

My first autocross on fresh RS2s was not pretty... my 2nd and 3rd were still troublesome.. but fast. Like I said, don't be suprised if there's a learning curve. They feel like mush at the limit on full tread.. push a little beyond where the limits feel like they should be though... they'll keep gripping. :D

Yeah I'm gonna be taking a little drive down a favorite private road to get familiar with the limit of the tires. It's also freshly layed down concrete so should rub in the tires well as opposed to asphalt or smoother surface.

What size rear swaybar you got there? Back in the day a guy with a 24mm would lift the wheel like that. With a 20 mine wouldn't go that high.
Imprezivblue 11-04-2005 05:41 PM

I also was lucky enough to drive a shaved set for the Atlanta Pro on Biggly's (Tom Hoppe's old) STX car. I liked them so much that when I finally broke down and bought a set of tires for my rims I went with the kooks and I will say I LOVE them. They've only been used for autox but they've seen a few rain events. I certainly can't complain as they love the rain and have withstood much beating from myself and sometimes an occasional codriver.

In my experience, the MX can't get enough heat, the Kooks like some heat but not too much, and the Azenis like cold.
ChrisDP 11-04-2005 07:37 PM

I like the Kumhos better as a dry TRACK tire. I like the Hankooks better for autocrossing and daily driving. The compound's awesome in the rain, and the pattern pumps out water very well. IMO they're better in the wet than my old Azenis 215s, and light years ahead of my MXs in rain. My car pretty much refused to turn on the MXs, whereas it's much better balanced on the Kooks in rain. BIG power oversteer in STX car on corner exit=good!

I agree on the heat sentiments... my Azenis seemed to be toast around 130, the Kooks fall off less rapidly with heat but still don't like it much, and the MXs still seemed to stick at 170. Response got a little softer up at the uber-high temps on the MXs, but they still stuck like glue.
PKer 11-04-2005 07:40 PM

The Kooks do well in wet transition, not so well in straight line wet braking though.
trhoppe 11-04-2005 09:04 PM

fwiw in my experience the kook had the best straight line traction out of all the tires. the azenis had the best transition and when hot the mxs had the best lateral grip. the kooks ended up being the best as an all around though and were faster overall.
makofoto 11-05-2005 02:19 AM

MX's came in last in the recent EuroTuner magazine test of 14 high performance tires. Unfortunately they didn't test the R2S's ... instead they tested the Ventus S1 evo K107 ... which also didn't do great.

MX's were particularily bad in the wet. Mid to low in the dry.

Test was done with BMW's on the Tire Rack test track/AX course - by Grand-Am Cup BMW race drivers ... who amazed the magazine staff by being able to feel the tinest difference between the tires. Tire size was 225/45/17's.

The Yoko's Adven's were top in the dry followed by the 615's

The Adven's were 2nd over all ... since the Goodyear GS-D3 were TOPS in the wet. The Goodyears were 2nd best in Dry braking but middling otherwise in the dry.

The 615's came in 9th overall ... 2nd best in the dry ... 2/3rds down in the wet. Note ... Tire Rack doesn't sell Falkens. ;)

Last year the Falken 215 came in 2nd over all. The 615 is suppose to be better in all ways over the 215 ... but the testers said the bad thing about the 615 was that it replaced the 215 ! :(

Paid $400 for my set of 235/40/17 kooks ... w/o mounting
Hotrodguru 11-05-2005 01:53 PM

Well hit a favorite country road last night and overall I like the feels of the Kooks alot. 1st time through a nice twisty section I took it about 5-10mph slower than I was used to on the MX's. 2nd and 3rd time through I was about 3-5mph faster. I also liked the feel of them alot better than the MX's when trailbraking for one particular combination. Time for AutoX tomorrow. I'm still on stock sways but do have a Ver7 suspension setup. I'd like to get a tad bit more oversteer out of them, what would you guys recommend for tire pressure. I'm running 42F/44R currently.

makofoto 11-05-2005 02:43 PM

36/33 ... or if you need more rotation, try going much higher in the rear ...
DrBiggly 11-05-2005 03:29 PM

[QUOTE=makofoto]36/33 ... or if you need more rotation, try going much higher in the rear ...[/QUOTE]
Yep.

The Kooks are going to feel a bit "numb" in comparison to the Azenis since the sidewalls aren't super-stiff like the Azenis. They also like lower pressures and lower temps, so keep an eye on them and keep them cool. Bleed excess pressure off after the first run or two to keep them consistent.

36 front is the target pressure for maximum grip, however the car will likely push a bit more than you're used to on previous tires so don't be suprised. This just means that girp went up everywhere and you need to find a way to remove some of that grip from the rear (pick a method, there are plenty.)

More camber is usually necessary up front with these tires due to a mid-soft sidewall and the fact that they have more lateral grip so the car will roll more so expect some edge wear at the first event until you get your car setup for the tires.

The bonus to the Kooks is that they recover being overdriven for a particular corner better than the Azenis and you can reel the car back in more quickly. There isn't quite as sharp of a dropoff once you've overdriven the tire...it's more like a rounded hill than a cliff. This makes folks that are used to the Azenis feel uncomfortable typically so don't be suprised about learning where the grip is for the tire. :)

makofoto 11-05-2005 03:35 PM

Turn in early! Might need to throw the car around a bit. Don't get behind ... you'll just end up scrubbing and having to lift instead of being on the gas!
MartinG 11-05-2005 05:09 PM

Here is a dissenting vote: I had no success with low pressures. With 35psi and -3.2 degrees of camber in the front the tires rolled over completely and the car pushed badly. Increasing front pressures to 40 and later to 43 psi drastically reduced lap times and got rid of the push.
Hotrodguru 11-05-2005 05:50 PM

Yeah guess I'll have to play around with it. Keep in mind I'm running a basic stock suspension setup with only -.08 of front and -1.5 of out back in regards to negative camber. I think 38/40 up front is about dead on but I need to get the car to rotate.

Are those the Dry Results or Combination Wet/Dry

In the EuroTuner test ... the GS-D3's were also on top ... but you wouldn't use them as your dry AX tire ...
makofoto 11-06-2005 02:47 AM

The Advens were first in the dry in the CD Test done at the Tire Rack test track ... they didn't include Falken tires ?! ... but they did include Toyo's and Hankooks ... which the Tire Rack also doesn't carry ?
Rich10 11-06-2005 06:16 AM

The Car and Driver test had a few problems. First, they ran all of the tires with 29psi front and 35psi rear. This will hurt tires with softer sidewalls. Next, part of the weighting was the treadwear rating of the tires. You can't really compare treadwear ratings across tires.

Based on the write-up, I was most impressed with the Yoko's (best dry grip) and Kook's (best bargain). I like my MX's (not that I'd ever run them or especially autox with 29psi in the front tires), but they seem to have lost a step on the competition.
makofoto 11-06-2005 12:57 PM

MX's were last in the EuroTuner test.

How would you do a Tire Test with a realistic real world budget that appeals to a wide spectrum of readers? There is no way they can fine tune the tire pressures for all of those tires. Even the Grassroots Motor Sports magazine tire test didn't do that. Any enthusiasts knows that you have to use more tire pressure then what the manufactures recommend as a compromise between comfort and performance. And that a competition car has to be set up around the tires. So the tests are just very general information. What we can see is that over three tests the (expenisve) Advens have been consistently fast in the dry (and wet) ... something that Josh Sortor proved at the Nationals. And that that the Kooks are pretty good for the price.
Hotrodguru 11-06-2005 02:55 PM

Well just ran my first AutoX in about 2 years and had a blast. Sure enough as soon as it was my classes time to run the skies opened up and we're talking Monsoon, not slight rain, rain or shower. Huge river crossing type puddles. I was really impressed with the lateral grip of the Kooks in the wet and liked them yesterday in the dry. The tires were very predictable and I think I ran a conservative 40F/44R with the wet conditions. I was happpy with the result, I ran a 65.4 in the wet (FTD in the wet) which netted a 3rd place cone. 1st and 2nd snuck in right before the rain and there times were 60.x and a 62.x.

makofoto 11-06-2005 03:32 PM

I went to 33/30 in wet conditions, from 36/33. But some people say that in standing water go extra high to crown the tires and open up the tread?

What did you think of the Kooks braking in the wet ... seemed pretty poor to me. Agree that laterally there were pretty good, with nice control.
REX8 11-06-2005 07:13 PM

Forget about the finishing order in tne CD test. Read the reviews...the 3 fasterest dry tires, were are the three normal suspects...the Yoko's, kooks, and ...an oldie but goodie (IIRC)

The test was geared to find the best overall summer tire, not the best autox/track tire. Forget about the positions, read the review. Heck, the KD's performed AMAZING in the dry, and finished at the bottom...

[QUOTE=makofoto]How would you do a Tire Test with a realistic real world budget that appeals to a wide spectrum of readers? There is no way they can fine tune the tire pressures for all of those tires. [/QUOTE]
I agree, but 29psi will penalize tires with softer sidewalls more than tires with stiffer sidewalls. I would imagine that all of the tires would have performed better with a minimum of 35psi. Why not run all of the tires at a tire pressure that someone would actually run any high performance tire on an autocross?
