What Size Tires?
I have a 2000 F150, 5.4l 4x4. I was wondering what the max size tires I could put on it with out a lift. I want a more aggressive offroad tread, and it seems that what I am looking I can get as sn\mall as a 33". Will this work. This is a daily driver that makes frequent long road trips, so I don't want to lift it and change gears, ect. I just want something a bit more aggresive that will help out in this South Carolina mud.
Thanks,
Mike

I have 265/75r16 (31.7") ALL-T's and will be switching to muddterrains soon but I've have no issues at all. Your speedometer/odometer/etc will be off which you probably already know and your jacks wont reach, atleast my stock ones didnt. 33's are kind of shady. Some people say you can fit, some say you cant. A lot of people have 285/75 tires (33.1") Many of them crank torsion bars to get the extra clearence, some say you dont need to. You can check my gallery to see the stance of the truck with 32's. I personally dont think it is worth it. I would go with 265's because if you crank torsion bars it reduces the max artiiculation flex supposebly, which I need when I go offroad. Its your decision, I think tire size is fine to hadle anything I throw at it, I do some rock climbing, and the hardest mudding I can find. I am going to switch to firestone destination M/T soon, need the extra grip that the A/T's dont offer.

Thanks. I think that's the answer I was looking for. I really don't want to fool with the suspension if I don't need too. Like I say, I just want something a bit more aggressive than what I have, but I don't want meaty mud tires either. I need to find that happy meaduim. My '00 truck is myu daily driver. Now when it comes to play time in the harsh stuff, that's what my '77 is for!

I'm running 285/75R-16 BFG all terrains on my 2001 Supercrew with stock suspension with 8 inch wide AR Scorpion wheels and they fit just fine. When I do the math I come up with 32.8 inches of height and I wouldn't want to try 33's unless I could actually measure them first. There are a couple of spots (like behind the front bumper) that are pretty close but so far no rubbing problems...even off road.

i have some friends that went with the 285/75/16 (rim 16). they look nice. just adjust the torsion bars so that it will lift from the front a bit to clear the tire. that'll give ya like 2-3 inches alone.

I recently bought a 2000 F150 4X4 that had 305/70 16's. These are 33" tall. Although they have no clearance problems whatsoever, I would highly recommend that you do not put tires this large on your truck for your purposes. If you spent MOST of your time offroad, then they might be a workable compromise.
When you put these tires on you are adding LOTS of rotating mass. Every pound of tire weight that is added, is equivalent to adding FOUR pounds of weight in the truck as far as performance and fuel mileage go. As far as fuel mileage, it probably hurts you worse, because you are effectively gearing the truck higher, moving the engine cruise RPM further away from its most efficient RPM.
Additionally, this extra rotating mass makes the truck harder to stop and thus shortens brake life.
I have never been one to look forward to wearing out a set of tires, but in this case it will be a relief to me when they are worn out. At that time I will put on a set of 245/70 16's on my beautiful Weld 8" wheels that came on the truck.
Best of luck,
Doc

It's raining and nasty outside and my pickup is tucked away in my shop building. I've been wanting to make pictures of it anyway, so I'll try to remember to do this and post them. The weather is not supposed to clear off here for several days though.
Have a great day,

I examined my truck very closely before buying it. It is for sure not lifted. Had it been lifted I would not have bought it. It could be that the torsion bars are raised very slightly in the front, but I doubt it.
The wheel offset might be critical for these tires to fit, but I don't know that for sure. It might be possible that the regular cab 4X4 is a little taller or something.
I hope to get pictures this weekend, but there's always the possibility of being covered with things to do.
Have a great day,
