Had both tires. Ran the duratracs on my old ranger and loved them never had a problem with them.
The fierce are as step up from the duratracs. I have had a set on my 08 f350 for about 15,000 miles and then switched them over to the 12 f350 and I'm still running them with half tread or more. I have just a hair over 20,000 miles on the 12. The fierce tires are the best tires I've ran. Wish they could make them in the size I need for my new rims.
Are you honestly comparing tired from a ranger to a 350? LOL
