We replaced our Eagle RSA's with these about 5K miles ago. I had it done early because I wanted to see how the performance characteristics were. These tires are on a Tahoe Defender (police pursuit SUV). I have run these up to 120mph and hit corners at 60mph. In all our tests the tire performed well coming in just slightly under the RSA's in performance. The tire is a bit softer than the RSA's and improves ride comfort noticeably. When they first went on they felt and handled like they where glued to the road, steering response was outstanding. At 5K miles the tires have lost a little of the glued feeling but continue to offer good handling and traction. Due to the nature of service a normal RSA lasts about 20K max on our vehicles. I think these will meet that mark easily. Our operating conditions are 50% highway, 40% urban roadway, and 10% soft sand. Our vehicles are 2WD and while operating on soft sand perform almost as well as our 4WD with these tires. The RSA's where very poor in sand and dug in easily. The surface area of the tire coupled with the tread pattern are well suited for light off road use. To summarize our experience the tire offers good handling, low operating noise, and a better ride overall. Handling comes in slightly below the RSA but the added traction in both wet and dry conditions make up for any short comings in handling. We will be operating these tires year round because of these findings.
