Rain AutoX tire 200tw

What do people seem to like these days?

I am thinking of putting together a set of wheels/tires that will be my running around/rain tires on my AX car.

Ideally with 15" fitments available 

The Continental Extreme Contact Sport and Extreme Contact Sport 02 are kind of the go-to rain tire at the moment, but 15s are going to be a tough get in any brand. Michelin MXW maybe? I think they might have a 15 option.

It's not a great answer, but the 205/45/16 Continental ECS02 has the same OD as the 205/50/15 and you can actually buy it. That would be my top pick, but understandably you might not want to get other wheels. 

The Conti ExtremeContactSport isn't 200tw but it's insanely capable in the rain, moreso than most 200TW tires. I have a set on the stock wheels for my MR2 Spyder that I intend to be the street and rain tires.

If you are looking at just one tire for wet and dry, I remember the old RE71R was also brilliant. I'm pretty certain the RE71RS continues that trend.

I can definitely tell you that Rival S 1.5s and the Nankang CR-S are both absolutely horrible in the rain.

ECS/ECS02 would be great if you can get them, other than that, for 15s your best options might be Toyo R1Rs or Yokohama V701s (although these are 300TW).

For 200TW tires, your best shot is the RE71RS. But for an actual good rain tire, I'd echo what everyone says here and go for the Conti ECS (340tw tires)

unless its like standing water type rain, a regular 200tw is still better off than a "rain" tire

I guess I should of been more clear...they do not necessarily have to be 200tw...but definitely cannot be less. 

I thought about the Contis...I have some beat up 16" motegi wheels I can use...just rather not and use my 15" Kosei wheels instead.

I just wasnt sure if I was overlooking some choices or not

ECS02 exists in 205/50-15...just not currently available from TR.

Looks elsewhere.  Somebodyt found some at Summit, but that source seems to have dried up.  Keep looking.

And yeah, worst case, go 205/45-16 on some cheap 16x8's

Just wet or cold and wet? If it is cold enough regular summer tires start doing better. Crossover seems somewhere around 50-60f.
