I'm an old farm boy that has had many different m/t tires on many different trucks. I currently have some m/t's on my suburban and they ride just how all my others have rode on the highway....loud and aggresive. I thought this was just a given until I drove a jeep the other day with goodyear duratracs. I could not believe how smooth and quiet they were on the highway. They were also a little bigger and had more miles on them than mine, so they were not brand new. I'm not sure if the duratracs are a really aggressive a/t or a really mild m/t. Regardless how do the duratracs do in mud and other off road situations? Anybody here have any experience with them? thanks.
