First set of Kumho tires I've ever purchased and I'm very pleased so far. There is a limited selection of tires for an E34 Touring, and when Michelin quit making these size tires, I purchased Kumho Ecsta LX Platinum. They are quiet, handling is excellent, and they perform fine in heavy rain. The BMW tech was surprised at how little weight correction was needed to bring them into perfect balance. No abnormal wear or issues at 4,000 miles. They cost substantially less than equivalent speed rating Michelin tires. I only averaged 50,000 miles or so on several sets of Michelin Grand Touring tires before they needed replacement for hydroplaning reasons, so I'm anxious to see the final mileage I achieve on these Kumho tires.
