Great Road Tires for an Aggressive Tread.

These tires are Great on the road. I have to agree with everything William said in his review, about these tires. I just got them installed and drove home on the highway %26 bumpy side roads. A very big change in the driveability / ride on my wife's Jeep Wrangler LJ. They are quiet, I didn't think an agressive tire could be so quiet. A verry slight hum at highway speeds. Almost silent around town. Our previous tires were very bouncy on any little bump, these hold the road, "what bump?". A very stable ride. They hold the road great at highway speeds %26 everyday around town driving. 65,000 mile treadwear, can't be beat. I have not gone off road yet but imagine they'll be great.

Don't think twice definitely get these!

I would have never believed a review that would change the ride of my Jeep Wrangler so immensely, I went from Nitto grapplers to these they look just as aggressive, but the ride the quietness has changed so much! They do not bounce all over the road with any little bump. They are much more stable at higher speeds much more quiet on the road and my wife who is very picky about riding in different vehicles, including my Corvette said that the jeep is much more enjoyable to ride them.
