I have a 2004 F-150 FX4 - I am running 325/60/18 Nitto Terra Grapplers on the stock 18 inch wheels with a 2 1/2 inch leveling kit and I am looking now at changing either to a 18x9 aftermarket - I want to go with a 33 - 34 inch tire --- I do a lot of highway riding and I am looking for something that will get somewhere between 30-35000 miles ===== the nittos I have right now - I am getting about 28,000 out of - do you think that will increase with a wider wheel --- or should I go with another tire - any suggestions at all - the wheel I am looking at is an 18x9 with 5 inch backspacing..... Please help...................


Or another possibility is a 20x8.5 with 4.6 backspacing and with the 325/60/20 tires --- what do ya'll think would be the best option?
I really want to go with the 20's
please advise!!!


Or to save money and possibly get a taller tire and not so wide - is there any way to run aftermarket 17's on the 04 fx4 ---- with out hitting the brake calipers??

 

As for tire milage, I have just shy of 50,000 miles on my BFG AT KO's and they look like they will easily go over 60,000. As, for 18's or 20's, that's just up to you and the look you want.
