really uneven rear tread wear?

For your birthday, Yellow Jacket, you ought to drive not like an "old lady," but like a speed demon!

HAPPY BIRTHDAY!

The Boxster has a lot of weight on the rear tires. On top of that, you're probably running a lot more negative camber due to your lowering springs. These two things add up to fast tire wear.

I wore out my rears in 10K miles at stock height. Unfortunately, as a daily driver, a lot of my miles are straight and on the freeway. A lot of negative camber is good for the twisties but bad for straight line.

I don't know what the factory camber settings are, but if you do a lot of straight line driving I would suggest no more than 1.5 degrees negative. Due to the Boxster using a Mac strut design, this might not be possible when the car is lowered.

which tires did you wear out in only 10K miles? wow, that's way less than a year's driving for me.
The funny thing is, ever since I bought this car I drive about twice as much as I did with my Miata.
I think I rarely averaged more than 7K a year with the Miata and since buuying the Boxster in November I have already driven nearly 4K. Lots of weekend miles

My pilot sports still look ok. I tried to do a burn out once or twice and just got a bunch of wheel hop. I even get wheel hop on the 1-2 shift lots of times. I guess IRS is good for corners...not so good for peeling out

why does the Boxster's rear wheel hop? I noticed in one magazine's(R&T?) 0-60 test they complained about "ridiculus amounts of rw hop".
I noticed this on another Boxster taking off during an Atuocross way before I bought mine and thought it was driver error. None of the rear wheel drive cars ever displayed this,better drivers?

Axel hop is a common character trait of cars with Independent rear suspesions. Solid rear axel cars are better for launhes( stangs, camaro's etc etc)

I have Yoko AVS Sports. I probably could've gone a few more miles but with the rain I was seeing at the time it was getting dangerous. Regardless, it'd be pretty much the same for all high perf tires. All of you getting 15K or so out of your tires, make sure that you check the inside tread as the outside can look fine. Tires are something you don't want to penny pinch.

I'd recommend swapping the tires side to side every 5K miles for max mileage. If you have directional tires, then that means having them unmounted and then remounted/balanced.

That's common for RWD vehicles......they go out fast and uneven. Even worse because you can not rotate due to the difference in wheels.

Agree with Lux - lowered suspension and excessive spacers all lead to increased tyre wear.

My Mich Pilot Sports are wearing better on the Box than the Contis did on a BMW 330 DIESEL (which lasted 9k miles in normal driving). Put Yokos on the BM and they were like new after 5k miles.

I'm reckoning on 14-15k on my rears and i do drive it pretty hard, but no track days or autocross

When I asked the service guy about the correct camber on my car he told me .5 was the factory setting sure looks like more than that, but who am I to say.

A sure sign of bad alignment is tire cupping. Easy to watch for this just run your hand along the inside edge of the tire, if adjacent treads feel uneven there is an alignment problem. The tires will go fast from this point.
