I was not spraying at "Night of the Living Dead" simply because it was pretty chilly outside. I certainly did not feel any drop off in tire performance over the three runs. I did bleed pressure between each run. However, I probably would spray them in the summer heat. I was running pressures of 39/37, but if Mr. Hoppe says 36 is the optimal number, I'll give that a shot at the practice next month.

I should not have to change my camber when changing tire brands. I will try more pressure, but I am not very confident.

Keep on dreaming there champ

You have to optimize a car for a tire.

I'm not sure Tom was saying that - he said that he found 36psi to be the ideal pressure if you have 4 degrees of camber. If you have less camber than that, perhaps a different pressure is better, but I bet it's not far off from 36.

I would say that with stock camber you will have to go up on the pressure a bit as to not roll over. The tire won't be at the optimium pressures, but you can't help that as you don't have optimum camber. So go as low as possible with good wear.

I don't think 36psi is going to work with like, -1 camber. That said, they do seem to work well with less pressure than the Azenis 215.

No I was saying that. I found that these tires will need a bit more camber then other tires that I have tried. Partly because they stuck more and I got a bit more roll out of the car with these tires. If you have the means to adjust camber, go with some more.

Good to know - thanks Tom. I've been running 4 degrees of camber with these tires and have certainly been very happy with them.

Hey BlkWRXWag,

Do you experience any of the things I was complaining about?

I'm worried that I'm just being overly analytical of the tires.

Tom, keep in mind that I'm not getting scuff marks past the shoulder line on the tire. Doesn't this mean roll-over is not what I'm experiencing?

Yea, you are also running a frikkin 205.55.16. Thats almost a truck tire Get a smaller size, 215/45/16 would eliminate a LOT of the problems you are having.

I'd be interested to know what the hydroplanning resistance of these tires is like once they get down below 50% tread. I guess I'll have to wait and see. I was going to buy these for daily drivers on my SE-R, but I bought the Yoko ES100s since I know those will do 25k miles and still have good hydroplanning resistance at the end of thier life. We get such heavy downpours here in the durty durty that an Azenis or a Kumho MX at 50% tread is a hazard as a daily driver.

I was kinda thinking the same thing. But figured they couldn't be any worse than the Azenis.

Well I have about close to 15,000 miles....
been on trips all over east coast lately, haha
and I think I have about 60-70% tread left
Ill post up pics later tonight...

last weekend in NJ, we had a crazy rain storm for a couple of hours
and I was cruising pretty normal because it felt safe.... didnt feel hydroplane and even running through deep long puddles I was able to control it. Car never felt unsafe really.... i dont know if there are certain tests I can do to check how good or bad the condition of my tread is for rain, but so far so good... when they start to suck in the rain, ill update again, hahaha

I have the Z212's in 225/45/17, and I really like them compared to my Toyo T1-S rubber.

With an identical 04 WRX following, I was able to take turns considerably faster with no squealing, while he was sliding with his Toyo T1-R's. The Hankooks are very predictable, and their grip in the rain are amazing.

Great overall, no complaints. I have only had them for 1800KM's so far, so I can't comment on treadware. But I will say that they look like they have been on the car for a summer already. I can't see them lasting very long. But with the extra grip they provide, I don't mind it at all.

After running these for a couple of weeks do you have any more input about the 225/50-16's on stock wheels? Do the sidewalls feel stiff enough?

Yeah, it looks like you're asking Justin (VikingMoose)... my name's Greg.
I guess I notice a bit of a floaty/balloony feel on the street as others have said, mostly when going over rough roads. This doesn't really bother me though. I still have the flappy noise when I go over any bumps in the road... this concerns me a bit, but I haven't seen anything bad come up yet. I'm willing to tolerate the street feel of these tires for their performance on an autocross course.

EDIT: Flappy noise was from the front swaybar clunking.

-Greg
