Odd Tire Wear at 13K Miles

[ciaranob]

I'll add to the thread with my data points. This is after 18k miles of daily med-hard driving, biweekly mountain runs in Northern California (Highway 9). The inside is consistently wearing faster than outside just like everyone else. I measured the treads remaining for your reference.

I plan to keep track of this with the Michelin PS4's I'm getting soon.

Honestly I'd be happy with those numbers (could be a whole host of reasons for the rel. minor variable wear rates) - my rears are near yours with only 5000 miles (Pirelli's and 21" wheels)!
