You can't rotate your tires, different sizes on the front and back.
Wear on the inside is typical to a degree.
Dealers have a master set of keys and will need to find the right one.
A lot of us change the locking lug bolt to a regular one so we don't need to dick around.

They told me a new wheel lock from porsche would be like 15 bucks if that's true i might just go pick one up tomorow. I'm assuming that they would have to custom make it right? It's not a universal porsche wheel lock is it? Cause then what would be the point? any porsche owner could steal my wheels and totally defeat the purpose of the wheel lock.

I looked at my rear wheels today after doing an oil change and the inside seems to be wearing faster than the outside. I want to rotate with the front tires but i need the wheel lock to do it so i guess I'm standing by till tomorow

hmm alright... oh and are the wheel sizes different from front and back or just the tire size? I'll have to take a look at my tires today i didn't notice that they were different. I'm sure they are not the stock tires though the outside of the tire looks brand new with plenty of tread left. The inside on the other hand still has enough tread to hold out for quite some time but you can tell it's wearing faster than the outside of the tires.

I'll go to the porsche dealership tomorow and get a wheel lock.

Size Matters

The wheels are supposed to be the same diameter front and rear, but they're a different width.

I see... that's for performance purposes i'm assuming? So that the car can turn easier?

Boxster History

Unlike the 911, the engineers at Porsche A.G. were able to start with a clean sheet of paper for the Boxster. Weight distribution, suspension, steering, wheel and tire size and selection were all chosen specifically to give the Boxster neutral handling. As little oversteer and/or understeer as possible. That's why we have different width and different profile tires front and rear -- to accomplish neutral handling.

Also, the inside of the rear tires do wear faster than the outside due to the negative camber setup on the rear wheels.

Normal (crappy handling) car's rear wheels look like this:

Your like-it's-on-rails Boxster's rear wheels are more like this:

/-o-\

Thus, the inside edges wear faster.
