2014 GT AWD, 36.5K miles, and my three original 19" toyos are at 4/32, so I've got another year on 'em. Strangely, I replaced one at 11,000 miles (nail in sidewall, still pisses me off the best I could do was $300 installed), and I can't tell which one that was anymore, as all 4 are showing 4/32...
