When I was looking at new tires everyone was pretty much in agreement that these were 'the' tires to get for a Jeep. And they were right. I have been extremely happy with them. Half of my daily drive is on gravel (roughly 16 miles) and it amazes me how well the tread has held up, as gravel just eats the tread off most tires.
I don't think that there is any additional road noise on the highway than the stock light truck tires my Jeep originally came with, which surprised me since these have a much more aggressive tread.
I'm getting ready to buy a new set for this coming winter and by then I should have close to 45,000 miles on these.
