What would I go with if I wanted a skinner tire but same height or 33 inch
I hate metric, tell them you want a 33x10.5x16. Let them do the math!!!!!
You will get better mileage out of a skinnier tire. The wider the tire the more rubber on the ground creating friction/traction however you wanna look at it.
Taller tire with these rigs wont make a huge difference on mileage due to the amount of torque we have, motor already pushing 8K plus, 1" or 2" taller tire wont make a huge difference, might actually improve your highway MPG, taller tire = less RPM's to achieve a certain speed. But if you tow a lot the motor needs to work a bit harder if you go with a bigger tire, your final drive ratio is affected with tire height.
That being said i run a 35x12.5x18 with 3.73 gears. 2K RPM's im at 70 MPH getting about 18.5 MPG (i have a heavy foot) Towing my trailer (roughtly 7K lbs) i drop to roughly 14 mpg, but i also keep doin 70 when possible.
