I bought the 2010 JKU Rubicon used, so I do not know what the 2010 came with originally. I will run either tire, I would just hate to get one versus the other and regret it, as opposed to asking the valued opinions of people who are already in the know. I do totally understand you will gain some things with the duratracs over the MTRwK and vice versa. Weight, noise, price, etc. I do not mind paying for one over the other since they are pretty close price wise.
Where I am confused is as I am doing research, I see the conflicting information about load ranges and C versus D versus E (which is a no go for me), but then in other research in this forum, I see many people loving the Duratrac which is not a C tire, yet the MTRwK is in the size of 35x12.5x17 is a C load tire and in total weight is only 4 pounds more per tire or a total of 20 pounds of extra weight and that's counting the spare. So the weight is neglegible, the price difference between the Duratrac and the MTRwK is $311 for the MTRwK for a 35x12.5x17 and the Duratrac is $282 per tire for the 315/70R17 for a total of a $145 dollar difference between the set of 5. My JKUR will be a hunting, beach, some DD use, fire roads and some dirt and mud, no crawling. SO which way do I go?
