100 tread wear r comp? Yes please. Looking forward to seeing this. I have 25k Street miles on my ra1's and may need to replace next year. Was looking at cup tires. Hopefully these are cheaper.

Not much more from me. Eagerly waiting for its release.

Hankook RS3 2014 still faster than Kumho V720 in Korea right now?

It's an interesting video to watch but all that test proves is that that specific driver was faster on the RS3 with that setup that day.
There are just too many variables for this test to be considered an "accurate" indication of how fast a tire truly is, especially for those of us in North America.
Consider the following:
-The tires we receive in North America are often different (compound and/or construction) than the ones sold in other markets.
-At least with EHP street tires, it isn't uncommon for different sizes of the same tire model from the same brand to have different compounds (Toyo R1R is probably the best example). This means that for all we know a 255/40R17 or other size could have a faster compound than other sizes… We don't know until we test for ourselves.
- The driver is a huge variable in this and the one in the test isn't all that consistent and he didn't look like he could keep the tires in a window of optimum slip angle, getting the most from them. Although this would indicate that the V720 is more like the ZII in that it's a more peaky tire and takes more skill to get the most from it (the top 5% or so of drivers are MUCH faster on the ZII than the bottom 95%) Where as the RS3 can handle bigger slip angles (like BFG Rival) and are typically faster for most drivers because they penalize you less for being sloppy.
- The car and and tire setup are other big variables and we don't know how things were how things were done. Setting cold pressures of the other tires to what the door sticker says for the stock tires might not be what the tire likes, especially for whatever alignment he was running.
- The last big variable I want to mention is the weather. We don't know how long he was on each tire and how the ambient temps, track temps and humidity changed from when he was on one tire to another. If it was within an hour or so it probably wasn't a huge change but if were like morning to afternoon it could have been a much bigger change.
They might be slower than other street tires when we get them. They might be faster. We really have no idea until we get them here and test them. I certainly won't be discouraged until I test them and compare to the data I have on all the other tires I've used. Just my thoughts.

That's an awful lot of apologizing for a tire that hasn't even shown up yet. Sure, it's not the final word in performance, but the preliminary results aren't looking promising. At this point you might as well buy tires that have been proven (RS3, Z2 SS) instead of holding out for tires which have not.

BTW is it just me? Or has the EHP tire market been somewhat stagnant? The last big hit was the RS3 back in 2009, am I right? I remember when the RS3s first came out, it shocked the EHP tire world because of the insane grip and dirt cheap price it came in at. But ever since then, there hasn't been a "oh wow!" type of tire?

I think many of us are hoping this v720 is the next "wow tire", but based on this test it clearly isn't, no matter the variables, because if it was a truly exceptional tire it would still overcome the variables to shine through. Why didn't the test prove to be in the v720 favor instead given the variables? I'm not totally discouraged by one test here, as I'm not putting the entire weight of the tire on one test, but again I'm not encouraged either. Its due to be out this spring, so we probably wont get a complete picture of this tires ratings until summer or fall. Still a ways off.

This makes me think the V720 could be more like the ZII in that it is more sensitive and that is why it was so far off the pace of the RS3 in this test. I could be wrong and it may simply just not be as fast as we hoped but again I won't be able to say for sure until I try it for myself.
