Tires Achilles or GT Radial

my Achilles ATR Sport 2 last forever in the rear and have good grip

I've been recommended Achilles ATR Sport 2 by literally all of my friends. I've had Pilot Super Sports before, and the Achilles handle extremely similar while intense driving. I'd say they last just as long as well.

I have had great luck with GT Radial so far.

Currently running GTRadial Chamiro UHP1 tires and am about to install my 2nd set. They are CHEAP and almost as good at the Direzza Star Specs on my Porsche. I was shocked I got 20k miles out of them, they grip really well and don't get greasy easily at the track.

I have heard good things about GT Radials... I use "Road Hugger GT Eco" (aka Kumho something or other) and they have been great. Low noise, (relatively) good grip for being low rolling resistance.

I bought a set of GT radial Champiro with the expectation that it will be just a crap daily driver set. They actually have really good grip for non race tires. Seriously, so much so that when I put the front set on and went to autocross, it caused my car to spin out because the front had more grip than the rear.

Tires are 235 40 18 GT Radial Champiro UHP1 Ultra-high performance summer tire ^ VERY sticky tire w/stiff side wall (nice handling and picks up lots of little pebbles - but I would not trust this tire below 40 degrees)

I also plan on installing the Achilles tires in the near future after powder coating my wheels, am anxious to see how they wear and handle

I wouldn't recommend Achilles tires in general. The bare tire (unmounted) flat-spotted under its own weight.
