I have similar tire questions to the one recently asked but I dont want to hijack that thread so here goes. I need new tires for my 2011 Chevy 1500 4x4. Should I continue with the all season highway style that I had or switch over to all terrains. I have been happy with the fuel economy that I get with the all season tires that came standard and also have never gotten stuck with them. Will I notice a giant fuel economy hit if I switch to ATs? Things to consider 1. I do a fair amount of driving off road on fields. 2. I foresee myself driving less interstate miles overall but still will make long trips yearly. 3. I am now picking up snow goose hunting. That means possibly scouting more and more on road miles but also possible more driving on fields or dirt roads. 4. I dont hunt close to home as much as I used to. Now I usually hunt 45 min away or so. 5. Up to this point I havent had any major problems with traction. What I am looking for is just some advice on whether or not the switch to ATs would be worth it in terms of fuel economy loss.
