The OEM Bridgestones on my '04 FJR lasted 10,750 miles and they were OK, not great just OK. I didn't consider them great on wet roads and they did have an annoying howl at high speed, and the front tire developed cupping at about the 5000-6000 mile point.
I have about 12,250 miles now on Avons, they are FAR superior, virtually no cupping on the front tire, no vibration and fantastic on wet roads. I love 'em. Will probably get around 13,000 miles before fully hitting the wear bars on both front and rear tires. Already have a new set of Avons in the garage ready to be mounted shortly.
