the 265/65 is 1 inch taller than stock and same width.
the 275/60 is .5 inch taller and .5 inch wider. so its going to look more stock than the one above.
I would go 265/65, its exact same as the 265/70/17, which is the most popular upsize out there for these rides. Probably have a better choice in tires with the 265/65 but i don't know that
Running spacers you will have to trim the front lower part of bumper and possible the mud flap, it won't be much trimming at all, so don't be scared about it.
