CAN ANYBODY TELL ME IF PUTTING 285/75R16 A/T'S ON A STOCK, NO LIFT, 2003 F-150 5.4L WILL CAUSE PROBLEMS WITH: RUBBING, BALL JOINTS, BRAKES, TRANNY, WILL IT BOG ENGINE DOWN MUCH, DECREASE GAS MILEAGE, SPEEDO, ETC.

WOULD IT BE BETTER TO GO WITH 265/75'S

PLEASE REPLY NEED INFO ASAP SO I CAN GET SOME NEW TIRES
HOWEVER I DO WANT TO MAKE GOOD DECISION ABOUT SIZE

I DO DRIVE UP HILLS QUITE A BIT, ACTUALLY EVERY DAY, LIVE IN WEST VIRGINIA ( AND NO I DONT KISS MY COUSINS, NOT FIRST COUSINS AT LEAST

 

It will affect your power. How much depends on your powertrain. I have a 5.4 with 3.55 gears. I went from a 30 inch tall tire (255/70-16) to a 33 inch tire (285/75-16) and didn't notice a difference. I'm sure I would have noticed a difference if I had a 4.6 or taller gears.

 

Appreciate that. im not sure of my gear ratio to be honest with you. i am running the 255/70s now and i do have a 5.4L.
