First off new to forum. Hoping several guys have some input. Just 2015 fx4 with a 6" lift. Currently it has 275/65r/20 on it and is like to go bigger like 295/65/20. My question is the truck doesn't really a great turning radius, will that jump in one inch hurt my ability to turn? Again I've got no experience so any help would be great before I buy the wrong tires

 

Turning radius is determined by suspension and steering components/wheelbase, not the tires.

Thanks.
