I have a 08 328 vert on sport suspension and always had issues with the rear chewing through tires in less than a yr. I always get an alignment after getting a new set but doesn't seem to help that much. Example, on the last set I purchase them in early Feb of this year. I get an alignment from J* Auto**** a few days after and express that the rear is always wearing prematurely on the inside and want it set for maximum tread life. Every corner gets adjusted to within specs but by Sept the insides of the rear are already chewed to the wires. Luckily I checked because I had a blowout before because they complete worn through, and yes I got an alignment done with that set too by the same shop.

I never had a problem with the front. They still look new when the rears are showing metal. I'm starting to hate having to buy new tires every few months. Will more frequent alignments help extend the life of my rear tires? $120 each time for an alignment will definitely hurt too if I have to up its frequency.

Dial out rear toe and camber.

These cars have a propensity to chew the inside of the rears. That's the cost of having a chassis designed to be sporty and have great handling out of the box.

Out or in? I was told he will toe them in a bit and the forward motion will then naturally pull them out, effectively zeroing the toe.

First thing to check is your suspension bushings.

Toe will affect tire wear more than camber.

If you have the car aligned with worn bushings, not only will the alignment not hold, it will dynamically change as the suspension is loaded.

I would start with trailing and toe arm bushings.

Yes, I meant to get it down to zero or 0.05 toe in at the most. Out was a poor choice of word on my part. You want a little bit of toe-in to help with bushing deflection under load. I found in the past that putting my 335's rear toe to 0.05 in and camber around -1.5 really helped prolong tire life tremendously.

Bringing toe closer to zero will cause the rear end to feel less planted. OP needs to check suspension bushings first

It's either that or deal with accelerated rear tire wear, even with newly replaced suspension components. Albeit it may not be as bad as he's currently experiencing.

Have been running the same tire?

As long as the final settings are within reason, that feeling of being "less planted" is actually preferred when compared to the crap end of the OEM spec range.
