When I purchased my 2014 Tradesman Crew Cab, it had 285/70/17's on it. I now need new tires, and the cost of a 285/70/17 is about $60+ per tire...I see the factory size is 265/70/17. I am assuming I am getting worse fuel economy using the 285's, but any other pros/cons other than looks to stay at the 285 size? I just cant think of anything. This is my commuter truck. mainly highway and we will be getting a Travel Trailer at some point (6800lb+/-) if that matters. Thanks in advance
