Any tire experts here?
I'm having some crazy tire wear on my rears. I made a post in the "Wheels and Tires by Tire Rack" section here but maybe with all of the post 
s in here I can get one of you to chime in. 
Any helpful advice or jokes to get my mind off of my ever increasing tire budget would be greatly appreciated!

I'm having a big problem with excessive tire wear in the rear. I have found several threads with similar problems but no clear explanations as to why.
I have an '03 with 32k on the odometer. The OEM s02's lasted about 16k miles. I then switched to +1 sized Avon M500's which lasted about 11k miles. Halfway through the Avon's I had the UK alignment done on the car. I noticed the Avon's were getting excessive wear in the center of the tire. I dropped the pressure down to 32 thinking the that the pressure was too high but the center wear continued.
I finally replaced the Avon's with another set of +1 Avon m500's. The second set lasted less then 5k miles until they were completely bald in the center. I had the pressure at 32 psi and drove very conservatively.
I have switched to Yoko AVS ES100's in the stock size to see if I can get some better results.
I would have thought with the UK spec alignment I would have gotten inner tire wear and not center. The actual rear alignment numbers are left camber -1.9 toe +0.21 and right camber -1.9 toe +0.18.
Does anyone have any idea why my tires are going like mad? Is my rear toed too much?

That's the first thing I thought of, I am not sure how the +1 sized tires affect things thouggh
I got 16K on my last set of S02s, I just changed them as they were just getting baldish on the inside and I didnt want to worry about them in the wet.
I have ~2.5 degrees of Camber in the rear.

This is going to sound very assholeish, but buy better tires. First, check your tire gauge
A very good set of inexpensive tires are the Kumho MX's - I got about 12,000 miles per set of rears......on my old S2000.
16K miles on S0-2's is a damn long time! You're not driving your car too aggressively are you?

Most of those miles were fun drives and the car was supercharged. I dunno why they lasted so long, I bought new tires last spring and just installed them a year later.

Avon's make some excellent motorcycle tires and I was very pleased with the first set I had on my car. The front two Avon's have at least half of the tread left after 16k on them.
I was going to try the Kumho's but they did not have them in my size when I needed the tires to get home from Hardtopguys. My driving is semi aggressive but certainly not hard enough to waste tires in 5k miles or so I would think.
The odd things is the center tire wear. I assumed my gauge was good since the tech put the pressure at 34psi and four days later my gauge registered 34 at which point I reduced the pressure to 32. But I'm going to use the local advanced auto's tire gauge to check mine.
I'm going to get it re-aligned after this weekend when Bill helps me put on my GC/Koni's. Hopefully I can get this sorted out.
