Hadn't thought about the ESP angle. I had mine replaced (rears) at 40,585 miles. My Durango went 85,000 miles before I had them replaced, well into my second set of tires. I was surprised that I had to replace them so quickly. A good 2/3 of my driving is highway so I was expecting much more mileage than that! And I hadn't even had the trailer that long, or towed it very far before the brakes needed replacing. Oh, well. Its a jeep. Just Empty Every Pocket. Mine especially (see my bad gas thread).
