I have a set of the Geos as well. I had some weird vibration and a rumbling ride for a bit but it turns out I had a bad front tire. I had that replaced a few days ago and the vibration has stopped. Overall they are a great looking tire, seem well made and beefy. For a MT they are pretty quiet any most speeds but there are bands of speeds where you can hear them like any other mud tire.I’ve been looking into the Geolandar. How does it handle the road? and are they loud on the road?
Overall these tires dont have the constant MT roar most do. Since I only have 600 miles on them its hard to say how they will sound or perform as they age.
Apart from getting a Toyo, BFG or Nitto my local Jeep shop said he would stick with them. I say stick with bc I was/am thinking returning them due to the rumble/knobby tire ride. I need to air down to 33 PSI before I make that decision bc that may help take the edge off the ride.
