AutoX Tires
I'm thinking of having a track set of wheels/tires for autox. I've been browsing past threads of what people recommend. But I need some insight that is more geared to my needs.
I'd be using 16x7 and 16x9 size wheels. And I have to drive to and from the event on these tires (about 30 miles each way).
So what tires and sizes do you recommend?

The Kumho 710 tire in the correct size would be best. Arguably as good as the other best,
which would be Hoosiers, and *much more long-lived and durable* if you drive on the
street. 225/50ZR16 front and 265/45ZR16 rear.

Joe...will the 265/45 rear be too tall of a tire?

You don't want to drive to an event on V710s -- they're essentially slicks. I'd recommend Kumho Victoracers or one of the hot street tires (Falkens, Bridgestone RE-01R) instead.

The two streetable long lived options that come to mind are the Victoracers and Toyo RA1. Both are DOT R compound tires. They may not be as fast as the V710s or Hoosier but are great for drving to and from events and being competitive.
I run the RA1s and have been very happy with them. If you are in a very competitive class and aiming for the class win and the current fastest cars are on Hoosiers then you may have to step up to the best rubber. That said, if you are completive already on streets RA1s will be good for about 2 seconds and Hoosiers for about an other second. This year I did a number of events on Toyo T1Rs. This was the first time on streets in many years. Very fun and very instructive.

I am typically 2 - 3 seconds behind the guys with V710s/Hoosiers.
I currently have Hankook RS-212's which are decent but I need more grip. I want to continue to use my Hankooks for the street and possibly DE's.
But I need something aggressive for AutoX. I'm thinking of going with the V710's. I average around 10 events per year more or less. So figure I'd put on about 600 street miles per year on these tires. Obviously if rain is in the forcast I wouldn't use the V710s. (I don't want to get stuck on the street in the rain with those!)
I've heard people unhappy with the RA-1's for auto-X. I was considering Victoracers, but I think the V710's might be better. I don't need another street tire.

v710 is hugely better than victoracers. If you want to compete, get the 710s. They are
good DE (track) tires too, whereas Hoosiers (autocross) would be gone in three track
laps. Tread is for sissies.

I run V710 on my GT3 and drive them to the events (no trailer or roof rack, etc). They are fine on the street as long as you aren't driving through standing water. They grip fairly well on a damp road too - just stay away from puddles.
Bottom line is if you are a competitive person, even for "fun" club autox events, you won't be happy with anything less than the V710. In my neck of the woods folks will tend to give the Hoosier slicks a slight advantage, but they never drive those on the streets.
Cheers,

It's not the mileage you should be concerned about (although that slows the tires down as well) -- it's the fact that you'll be driving on slicks. If you get caught in the rain, your life expectancy will go down dramatically. 
Not true -- many (most) of the Hoosier drivers at RunOffs were on the autocross-compound Hoosiers.

I do like the Hoosiers because they have 245/45/16 size. I'm worried about having enough clearance for the 265/45's that the Kumho's come in. My car is pretty low right now.

The Hoosiers are much less durable than the Kumhos, so if you really must drive a basically slick R-compound tire on the street, please at least do it on the Kumhos.
Why not just do it right and buy a tire trailer?
