This is going to be an ongoing review of them. I have searched the Internet and have not found a lot of info on them that was unbiased. I bought these tires in 32x11.5x15 according to the Cooper website the actual diameter of these tires are 31.57 with a tread depth of 20/32 and a load range of C. These are the first set of mud tires I have ever owned. I currently have about 150 miles on them. My initial thoughts on the tires are they are a awsome looking tire they have a aggressive tread design and deep lugs. After my limited amount of driving I have done on them they are quite not much louder than the all terrain tires I had on my xterra previously. So far I have had them on some ice and in my opinion they done good going up a ice covered hill in 2x4 where normally I would have had to use four wheel drive. I do think that the sidewalls are stiff and will be doing a chalk test and adjusting the pressures to see if this will help. Later this week I will be hitting some of the dirt roads after they melt some to see how they do. sent from the middle of a corn field.
