really uneven rear tread wear?

[Perfectlap]

just my experience, when the tires start to go they go quickly. I check my tire pressure with each gas tank 32F and 34R. (It was the other way around with my old car) and usually do custom alignments where negative rear camber is maxed out. But with this Boxster I decided to stick with Factory specs. I figure Porsche would know better than me.
Accelerating hard/often from a stop (red lights) will significantly eat into your rear tread life.
Your car sounds like it was tweaked often, did the previous owner go beyond Factory specs?
From reading the Porsche reviews on TireRack.com 24k sound like you got your miles worth. Some reviews complained about only getting 15K out of PS's.

I noticed that due to the positive camber of the rear wheels as I see them on my boxster from the back, it would just make common sense that the inside edge of the tires would probably wear more than the outside edge.

With this in mind, I plan on having the rubber knocked off my wheels and mounted on the other side. I have dreamed up this strategy to rotate tires that are unidirectional. Thus, the inside of the left tire become the outside of the right tire.

My mechanic told me that if I didn't wait forever to do it, it would extend the life of my oh-so-expensive tires. Thought I'd post this for others to consider.

If you know why this would not work, do post it here so I can have my common sense realigned and balanced, not my Boxster

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

[Perfectlap]

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?

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.
