Need a tire for 2010

[TitaniumTT]

Pulled the wheels off the FC yesterday and realized that I should've reset my front camber to something SLIGHTLY less aggressive for the street. For auto-x it was great, even temps across, but running them for so long on the highway with a ton of camber worn the innards a little past the wear bar, so it's time for some new shoes.

Rims are 17x8+35 and 17x9+35.
Was running Azenis RT-615's. I LOVED them in the beginning. Towards the end of thier life they seemed to get heat cycled and hard and on more than one occasion the ass let loose when it normally wouldn't have, and I alomst rotated the car once.

Tire being considered are
Another set of RT-615s
Nitto NT-05's
Nitto NT-01's

I seem to drive about 8-10k a year with alot of highway. Lots of Auto-X and a few track days thrown into that as well. I do have a dedicated set of RA1's for that, and those will be bumped to either a victoracer or the A6's.

So, what's everyones consensus for a street/auto-x tire with decent life. (The rears are in great shape, depth wise, but hard, it's just the fronts that are excessively worn) Wet traction isn't all that important, the only time they will see the wet is if I get caught in a storm on a road trip.

Also, sizing.... the fit seems good, but could I bump the fronts to a 255 on an 8" rim and the rears to a 275 on a 9" rim? All three tires are available in those three sizes.

So, suggestions?
