I just put some new tires on my stock ranger. I wanted to upgrade to a bigger tire but keep something that isn't too crazy on the tread. I decided to go with the Sailun Terramax H/T and am very happy with the tires. The size is 31x10.50R15.
close up of the tire:
The tire is about 1" bigger then my old stock tires and makes the truck have higher stance. There is no rubbing so far, haven't had a chance to flex the tires.
