A046's are stickier than RT-615's size-per-size, I think.

RA-1's are stickier than both, though there are some disadvantages of running a race-compound tire on the street. They will lose their wet performance very quickly as the tread gets below 4/32nds and they will throw rocks all over.

 

I think the stockers are by far the best street tire for the Evo. No other tire can match all ofits qualities. This has been discussed in many threads and I believe the consensus is that the A046 is still the best street tire for the Evo as far as performance is concerned.

 

For that matter, it's the best performance street tire for an STi as well (if you're willing to sacrifice wear for grip).

The STi's narrower RE070 has a longer treadlife than the Evo's A046. However, the A046 is a much grippier tire. It is wider, but it is also made of a softer compound. I want to get a set of Advans to run on my STi next. I think that many comparo's would come out differently if the STi came on the same great tires the Evo comes with. Hey, there's a reason the Advan costs $250 per tire on TireRack.
