I need new tires but not sure which to get? Size, make, model? 2006 Canyon Crew 3.5L SLE Z85 2x4.. Comments are appreciated.

I am hoping to get insight before I buy a set soon. Mostly road miles, local and some out of town driving. Florida panhandle region, so we can run across some soft shoulders and sandy areas. Stock for this truck is P225/75 - 15. I have stock 15" rims on it now. I want upgrade with something better than stock grade. Hopefully somewhat low road noise with decent gas mileage but able to handle some stuff here and there. Any sugestions and comments are greatly appreciated.
