I just got a set of Michelin Defender 225/65r17's recently. It's only been six days, so not much driving yet. Initial thoughts from me are, a lot more smoother riding, and quieter. I looked at the Premier also, but for a few dollars more the Defender had a 90,000 mile limited warranty as compared to, I believe it was 70,000 for the Premiere. They were $165.00 per tire at a Discount Tire store. I went to Discount because over the years they had fixed two slow leaks with no charge, and I had never bought anything from them. That is the way to gain customers.
