I took my car in for an inspection, and they told me what I already knew. My tires were shot. Kuhmo Ecsta ASTs that have only been on the car for maybe 6 months, and they had even been rotated. It turns out my p5 was in serious need of an alignment, which explained the extreme tire wear.
The bottom line... I needed tires.
I started shopping online for tires and found that Tire Rack had Goodyear Eagle F1 GS-D3 in size 205/50/R16 for $49 a piece. And if you buy a set of four, there's a $50 mail-in-rebate. Ultimately it worked out to be $190 for 4 tires shipped. That's a steal.

Also, if you're lowered and you've never had an alignment done, then do it! It made a huge difference in how my p5 handles, and the tires should last longer too!
