trust me you will want to because of the way it looks u will want it to look, how do i say it? symmetrical or right, with little tires it looks goofy so down the road on your next tire change grab the next size up or something that looks better on it

 

if you have 4.56's with 265's yeah you will get very crappy gas mileage on the highway.. you will be tacking probally over 3,000 just cruising at 65.. but if you have 33's wth stock 3.55 gears thats killing your mileage.. the engine is working harder to turn those bigger tires.. the way i see it is
265's-285's = stock 3.55 gears
295's-315's = 4.10's
anything over 315's will take 4.56's so your mileage doesnt drop to 3mpg

 

That is pretty much what I have now probably going to downsize to 265's my next tire change

 

how much better milage do you think I will be getting if I switch from 285s to 265s with the 3.55 gears? Couple of tenths?

 

a good 1-2 mpg i would think which really adds up over a month.. extra 50 miles a tank.. 200 miles a month..
