Super Fast Rear Tire Wear

[Topless]

A neutral alignment with minimal toe-in will help. Conti DWS and other A/S tires with higher TW rating will also help extend tire life... and driving your Boxster like an old lady.

Personally I shop for sticky, low treadwear tires and hope they only last 5k miles so then I can go buy a set of some nice fresh ones every season. I know, it a sickness...

If his tires are wearing evenly, it couldn't have excessive camber (I don't think). But toe could be off. I believe excessive toe in or out is what's meant by "dragging" tires. Could also be sticky tires (I don't know how sticky the Potenza line is), which wear really quickly.
I can also attest to the Conti DWS. They have been on my weekender Boxster for nearly 8,000 miles and show very little wear.

Just replaced my rear Potenza pole position s04's after 13000 spirited miles. The had very even tread wear. Sounds like you may have too much toe in.

Hello,

don't adjust only one axle. This is a system with 4 wheels. And these 4 wheels work together. If you want a setup for track i also would recommend to ask somebody who knows what he is doing. And also it will be a big plus if you know what the car should do to support your personal driving style.

If you would have to much negative camber, the inner side of the wheels would wear more or your tire profile would get a sawtooth pattern.

I think it's more a toe problem. But be careful when you adjust toe to 0, because you need some toe in the rear to stabilize the car. Also because of the toe differs on how much the suspension is compressed. Maybe it's not that important in the US where you can't drive more than 75 mp/h. But on the german Autobahn you will be very glad to have toe in the rear above 200 Km/h. And don't forget it's a rear wheel driven car with a mid engine. If you have lowered the car lately you should also adjust the alignment values.

Also some tires tend to wear more than other tires. I don't know these Continental DWS tires, because they are not available in Germany. But maybe they have a harder composite gum and so they last longer.

@jakeru: In general modern tires are directional and have a stamped Outside on the flanks. It's not only the profile it's also the tire carcass that won't allow to exchange tires like you suggested.

I just had my rear tires dismounted and remounted inside-out, as discussed above in this thread, to help even out future tread wear. They are performance all-season style 18" Michelins and although directional, were not asymmetric (so in other words, while there is a proper direction of rotation for water evacuation and hydroplane resistance, there is no "inner" and "outer" side of the tire.)

This "flipping" procedure has the added benefit of also rotating the tires from left-right sides of the car (it's actually necessary while flipping a directional tire to do this to maintain the right rotation direction), which can't otherwise be accomplished.

I feel like it's going to buy some extra life, and driving home they also felt surprisingly great!

Too much toe is probably the single most important cause of wear on the inside ofthe tires. And yes rotating will really increase tire life.
