Im going to replace my stock tires with either of these in a 25/70/18... which should I go for??? The coopers will be about a $160 more for all 4 installed. Im leaning towards the Cooper ST. I like the look of the tread better. I am probably a 80/20 on/off road driver, but I have to have something that can handle some mud..... anyone who has anty experience with either would be greatly appreciated since Im gonna get a set put on this week!!!!
