if anyone doesnt really like those tires, which ones would you prefer for a daily driver/autocrosser FD?

I ran the MX on my WRX, and I liked them. They aren't going to be as fast as some of the other max performance tires, but they worked well as a dual purpose tire.
As a bonus I thought the MX was really good in the rain.

The MX is a pretty good as far as streat tires go. If you're determined to go with a street tire I don't think you can get much better bang for your buck than the Hankook Z212 tire:

The Falken RT-615 (or what ever the new one is) was supposed to be out in a 225/50/16 this fall. Vulcan tire usually has good prices on those.

Yes, when this comes out it will be the best "street" tire.

The people I've talked to in the SCCA Texas Region all recommend the Falken Azenis tires. One of them had a top 10 car at Nationals this year running on Azenis.

the old azenis rt215 drive like a race tire but have a grip of a street tire, a very good street tire. but they do have all the negative things that the race tires have, sudden breakaway, they like low tire pressure and so on. they also get greasy, so if you push the car hard it starts to loose some grip after a few laps, the tire is also not consitent lap after lap. the new rt615 adress most of these problems but not completely. i havent had a chance to get much tim eon teh rt615 yet. the good thing about the rt215 was the price the rt615 cost 1/3 more, for that much more monwy there are a lot of other choices. i personally would think twice before going with azenis on the street car.

Huh? I have always experienced more linear breakaway and run higher pressures with race tires than with street tires. The azenis don't seem to do great in the cold and they overheat very easily. Their optimum operating range is kind of narrow. I recommend the Hankooks for a daily driver, the azenis if you are only racing and driving in the warm and dry weather, but if you seriously autocross your car like 15-30 events a year expect to go through 2 sets of street tires. When I raced on street tires I would go through a 2 sets of max summer tires a year and run all seasons for about 4 months a year. Now that I run race tires I go through about 2-3 sets of race tires a year and all seasons which last years anyways are getting more miles on them.

if you are new to autox, i'd go with the kumho mx for now. drive it on the street, autox it, learn on it. once your times are on par consider a dedicated set of rims with some r type tires.

Look in the current Grassroots Motorsports and look at the tires that the National autocross winners run on. The bulk of them on track tires are running the Khumo 710, evenyone on street tires are running the Falkins.

If that does not do it for you, pick up the Grassroot Motor sports from a couple months ago and read the article Blck Magic (a tire test). The second best street tire they tested was the Azenis 215, the only tire that beat it was the Azenis 615. They are in expensive, race proven, and tire tested as the best...why look at anything else?

And for autocross, the guy I mentioned earlier with the top 10 national car that runs on Azenis sprays them down with water after every run.

GRM tests tires just for that, performance on the track. it tells you ABSOLUTELY nothing about how well the tire will behave DAILY driving. i think either the mx or the rs2 will be a better choice for something that you are planing to drive on the street and autox.

I ran the old falken 215 azenis on my 7until there was just a shadow of tread left. they were great auto-x tires and very good on the street until the tread was gone.
they still had pretty good grip for auto x althe way thru. I plan on buying the new faulkens 615 this spring for sts2 class.

The Azenis is soft and heats quickly. If it is hot outside you have to cool the tires or they get greasy very quickly. You cannot over drive the Azenis or it will go away.

Jacobcartmill, the Kumho MX is a great tire and it's cheap to boot. Do a search in the Suspension section as there are lots and lots of comments on it there.

My MXs were great when I got them. They got better with heat. IMO, they dont hit their optimal temperature on a 60 sec autocross. However after 1.5 years and many autocrosses, mine are pretty much worn out. Once these tires hit the end of the life, the grip dies out. I have a set of azenis 215 on my miata and they are pretty good. I'm pretty curious to try one of the newer tires out there. I've been told that the new Hankook is pretty good, as are the Yokohama Neovas and the New Azenis.

I ran shaved Kumho MX's on my GSL-SE and liked them once they warmed up, I currently have a new set of Hankook RS-2 Z212 tires on the stock 16x7 in 225/45-16 that I really like......at full tread, they feel similar to the Kumho's, but like the MX's need to be shaved for maximum performance.

The only full-tread street tire I recommend is the Azenis RT-615, or to an extent the Yokohama Neova (great tire, even better shaved...better than the Azenis).

Ran the old RT-215 on the STS Honda last year, awesome tire.
