I corner and brake very aggressively though. I put the IS to work. So I make the suspension squiggle and wiggle under high turning and braking loads (many times simultaneously) which can cause the wear. It's worth it due to how fun it is.
If you're a gentle cruiser, you could go long.
Not bad. Mine started showing at 15k.

Are you on summer tires or all seasons? Cause the summer tires here in socal heat put a lot more stress on stuff. especially with stock F sport pads which are professional high friction german compound
i also wear front pads at around 11-12k
i also wear front pads at around 11-12k
All seasons on stock F sport rims

For those analyzing their 3IS tire wear, make sure you turn the wheel at full lock and closely inspect the inside of the tire. I've found there's a fine line between OK and HOLY S this has to be replaced that can sneak up on you fast. The very inner and very outer should be close. Look for signs of a "stripe" appearing on the very inner edge. Usually occurs around 10-15k, and maybe 20k if you drive very conservatively.
Say FOR EXAMPLE that you just got a (almost perfect) 4 wheel alignment, OR, your wheels are pretty much (almost perfectly) aligned, then this issue is mitigated correct?

No, you need stiffer LCA Bushings to mitigate the dynamic toe from braking and cornering. Otherwise, you pretty much will keep getting inner tire wear.

Or you can go Poly like RR Racing or Figs but those are extremely stiff and require lubing here and there. You’ll also increase noise, vibration, and harshness. These however will completely rectify the inner tire wear. I went with the RCF/GSF they seem like a good in between.

I believe RR Racing explained mechanics of it there.
