What changes to expect from tires??
 

I have been reading the different threads on here about tire sizes and how they affect the vehicle (loss of power, drop in gas mileage, etc.) What I need to know is, will moving from my stock 265/65/17 to a 265/70/17 cause any noticeable change? This is a very small increase so it may not matter, but it is the biggest I can go without rubbing on my 03’. Any advice? Thanks

You won't notice any difference. You're only gaining about an inch of tire height so you probably won't even be able to tell.
