only an in.(1) larger then stock can be run even without a lift, i ran 265/70/17 (1in, more) than 265/65/17 stock & only had to move the inner fender forward a bit,(only cause it rubbed backing up while turning) its real easy & you cant even notice it. im not sure what the 265/75/16 are but again, if there only an in. more, then yes. there is someone in this forum that got 275/70/? to fit, with no lift. to sum it up, if your on a tight budget, the 1 in. front only lift (spacer) will work & look better with the size tire you stated. wheel spacers are not needed until you go to 285s & maybe some 275s. unless you like the look of it, the 3/2 lift is only needed if you go 285s, again unless you like the look. ive got the 2/1 with 265/70/17 cause to me it looks better , i did have to trim abit cause of the wheels i used. if you want, pm me your email add. & ill send pics . in case you dont, & money is tight, youl be fine with a 1-2 in. front leveling kit. remember tho, that the front raises twice that of the spacer thickness, so 1/2 in. spacer = 1 in. lift, - 1 in.spacer = 2 in. lift.
