Since I am running in Street Tire class like Redlinetoy, I will be running on my stock Yoko A046 till they are done for. Then I planned on swithing to the Azenis RT-615.

What I really want to know is what makes the Azenis a better AutoX tire then the A046. Below are the specs

Tire Price Size UTQG Tread Depth
A046 $244 235/45 17 160 A A 9/32
RT-615 $170 245/45 17 200 A A 8/32

The A406 is more expensive and a faster tread wear. Seems like the stickier tires have a lower treadwear. Why would a tire that wears faster and has the same traction/temperature cost that much more then the #1 rated tire for AutoX. Thoughts?

Because, although it is better for autocrossing, the Azenis get squishy at the track, something that doesn't happen to the A046. I have run the 215's and I have a buddy on the 615's. The 615's did better in long runs, but still got greasy, and slowed @.10 per lap every lap after they got 'hot'. My 215's would go away after @ 2-3 laps on a 1.8-2.2 mile course, depending on heat outside.

The Advan can take serious abuse, with little drop-off in grip consistency. So, like the ladies would say, it isn't how hard you hit it the first time, it is how long you can hit it hard.....

If you met my wife, no it can NEVER be hard enough. I swear, I will die before I am 40, but that's ok, because I am married with children....

3 more thoughts to get this discussion back on track to show why the Falkens may be a better choice.

1. Wider tires are almost always better for autocross. You can get the Falkens up to 275 in a 17" diameter. In your example, 245's are obviously wider than 235's.

2. Treadwear is not exactly a regulated science. It really only lets you compare tires within a manufacturer's offerings. You can't necessarily say that Falken's 200 is any different than Yokohama's 160.

3. Falkens are much cheaper than Advans unless you can get used Advans. And if you are like me, you'll go through more than 1 set of tires a year so price is important too.

They're roughly comparable, I think, but what makes the Azenis more popular is primarily the cost. $70/tire is substantial when you're talking about two or more sets/season. Of course, the fact that the Advans only come in one size is also a factor in their overall popularity in the Street Tire classes.

Don't read too much into the difference between 160 and 200 tread wear ratings...there's a lot of slop in those numbers, and if you're shaving the tires, they mean even less. And the traction ratings in the UTQG are for wet traction. The extra 10 mm width in the Azenis will be a bigger factor than any of those specs except price.

The down side to the Azenis and something that I keep coming back to is that the 245/45 is a taller tire and if you're on coilovers or springs, you will have rub issues. If you're lowered and want to use 615's then it might be better to go 225/45. The other down side is that while I agree that wider is better but not when it comes to adding more rotating mass.

I would probably choose to go 245/40 if you're looking to go wider but that limits your choices to either the Advan Neova or BFGoodrich KD. Both are in the discussion except the KD is not the best choice in terms of wet traction. I would stay away from Kumho MX's unless you're really on a budget. They can be competitive but the sidewall is too weak for the Evo.

With all of that said I always come back to the same conclusion, the A046 is best choice for the Evo in street tire classes.

The neova is better in all ways, including price.

Once the 615's get hot you'll be sliding all over the place. With the advans I never had that problem as bad as the azenis. I have 245/45 615s with JIC coilovers and no rubbing issues. Once these tires are done I'm stepping up to 275s but probably not 615s.

The only problem with the neova is that it can't be used or stored in temps below 15 degrees F, which is something we have to look out for here in Colorado.

So buy them in the spring and throw them out in the fall

I am soon going with 18's for street driving and will be on 615s. The factory 17s will have the advans till they wear out, then either another clean used set of advans($), or possibly a dot legal comp tire just for track days/auto-x.

The current advans I have on put in a tough weekend at a recent track day. They didn't get very greasy, even after multiple hard sessions. They started to make a bit more noise at the end of the day, but were still quite grippy. It's a great tire, just expensive to replace frequently, if you drive hard or have agressive alignment/toe setup.
