Hello all, I have a question questions I'm sure has been answered a million times, but I couldn't find anything on it. I currently have 285/70/17 on my truck. I have a spare tire, but got a free Falken Wildpeak at work, which I want to use as my spare. It's a 265/70/17, a little smaller than my stock. If I get a flat and replace it with this size, will there be any issues driving on it until I get to a tire shop? This is my first truck I've owned, so all this is new to me. Thanks in advance!
