I've got a question about which tire size I need. I currently have Terra Grappler 305/50/20 tires. I want to keep the 20" wheels and go with Nitto Mud Grapplers. How do the 33" tires look as opposed to the 35" tires? Will there be a big difference in gas mileage? Are the tires I currently have 31" tires?

 

i believe that is pretty close to a 33" go to nittos website and look to make sure

 

A 305/50-20 is basically a 32x12.50 tire. A 305/55-20 is a 33x12.50.
