Has any one lifted there trucks that pull a goose neck trailer. I wanted to do a 6 inch lift and wanted to know if it will work. And what size tire can I run on a dulley. Thanks

 

If you get a 4" lift that uses rear blocks you won't reduce your loading ability. To get a soft enough ride with a 6" lift you'll need really soft springs and airbags to tow anything.

 

Watch the clearance between the bottom of the GN and the truck bed sides when lifting the truck. You'll change the angle and could be a problem unless your trailer is really tall.

Also, could make the rig combination unstable and definitely reduce your mpg.

Search for posts on tires, dually to get some good feedback. Believe the dually design limits the size of the tires because they are side-by-side.

 

Welcome to FTE.

I have run 265 75R 16s for around 100,000 miles. I keep the tires at 80 psi and never had any problems. That is about as big as you can go.

Good luck.
