yeah that is general going bigger knowledge but how much so with the actual titan application is whats in question.You can fit anything with a sawzall. Performance will change due to increased height (which raises your effective gear ratio) and increased weight (which is a major drag on starting and stopping the truck).
keep us updated on the results !I haven't gone to 35s yet (might one day, but not today). What I can tell you is, 10lbs of tire weight is worth about 1mpg - and that's keeping the same size tire - for my Titan. Went from 48lb OEM tires over to 58lb replacements, lost 1mpg. No height change at all. About to go to 34s (1" increase in height) after I install my lift (hopefully this weekend), and will see what that does to mileage. Only increasing about 2-3lbs for the shift in tires this time, so hoping MPG won't be affected too much.
