I decided to sell the TRDs and found a great member here to buy them. The MT/Rs are on my OEM Trail wheels and now sit stacked in my garage. I think I am still going to use those off road instead of the DuraTracs, as the sidewalls are so much tougher. Then again, I see guys like Marc have really put the DuraTrac through some tough terrain without fail.
Interesting note: The MT/Rs in 275 are 57 lbs. each. 285 DuraTrac is 53. The Trail wheels weigh 29 pounds (27 on the TRD, in case you are wondering), and the Countersteers only 20. So from the factory wheel I have now reduced my weight 13 lbs. on each corner. It is absolutely noticeable on the highway above 65. It was that 65-80mph that had me constantly downshifting w/ the MT/R setup. I'm sure the 285 DuraTracs will require some as well, but there are a few spots I hold now in 5th gear that I used 4th w/ the MT/Rs.
Really just wanted something more mild than the MT/R for my highway and winter use, and the DuraTrac fits the bill. Almost went with Silent Armors, but the anthracite Konigs were just too beautiful to wrap in those.
