So I want to get these E rated tires off my new Mountaineer and go with a G rated tire. I had the G-614's on my last 5er but these Sailun tires are getting some good talk... What's up with these tires...
Just for the record the S637 is about an inch larger in diameter vs the G614 or standard ST235/80R16E, so make sure you have the axle spacing required. Which would be at least 33" center to center! You will loose 1" between tires is another way to look at it. Dexter you should have 1" or more between tires.
