V12's for me too. The fronts have 25K miles on them and still lots of tread.

My rears had issues with wear, but an alignment seems to have fixed that.

I had a pair of rears wear down to the belts in 6k miles. I had done a cv boot replacement and I just marked the adjusters when I took off the suspension. We'll I guess I wasn't close enough.

Anyways burned through $600 worth of rubber in 1 season. Lesson learned. Yes - tires are that expensive in Canada.

After alignment, my rears seem to be getting decent wear.
