Read this topic and got a bit concerned... ran out and measured the tread depth on my 265 Michelins. I just rolled over 24000 on October 6th... Moby Truck's 2nd B'day. They have 9/32's on average. I do a front to back rotation every 10K, and keep them aired up to 55# unless I have a heavy load, then they go to max.
Typical drive is unloaded, general transportation. I do keep a fairly close eye on inflation pressure, check about once a week.
Previous ride was a Pathfinder, Michelins on it went about 48K, ended up with Costco's brand of tire, Kirkland Signature i think. The guys at Costco said they were made by Toyo. Hell of a good tire in the rain, had 60K+ on them when I sold the car, and they still looked good, but only load range C.
