I've noticed something since I've been driving my stock suspension/tire 2-door JK. It seems to wander in the lane a bit when going down the road [even perfectly smooth roads]. I don't know if it's because of the lift, the mud terrain tires or just natural characteristics of the vehicle, but it seems I can't keep the Jeep perfectly straight in the lane. My other vehicles I can easily keep it arrow straight in the road. Maybe it's because I can't see the fender flare when driving? But in my other car, I just use the corner of the windshield that meets the dash and a-pillar. I tried using the dash tweeter as a reference, but it still wanders from time to time. Does this happen to anyone else?

 

Solid front axle and mud terrains tend to promote that in my opinion, short wheel base doesn't help either.

 

Don't know what you're running for air pressure but you might want to lower it and see what it does.....

 

What is the suggested psi for the mud terrains?

My previous car was a short wheel base sports car. But then again, it had full front and rear independent suspension with upper/lower control arms and coil-over shocks with 18x8 summer performance tires. Apples to oranges

 

Since I upgraded to 35s I've noticed my Jeep has a greater tendency to follow ruts in the roads. Oddly enough the ruts in the center lane of a major highway I often take are wondery, go figure.

 

I'm running the stock size mud terrains on the factory 17" wheels.
