So I am pretty much decided on some terra grappler AT's for my stock 07 fx4, to replace the factory BFG Rugged Trails. I was going to go up from the stock 275/65-18 rugged trails to the terra AT 285/65-18's..but the 305/60-18's are the same price, and hey, bigger is better right?

Will these work *without* a leveling kit? I can't afford to go much taller than the stock rugged trails as I need to clear a parkade... but according to the manufacturer websites

Terra Grappler AT
LT285/60-18E1 123S B 31.5 11.50
285/65-18 XL 120S B 32.52 11.22
305/60-18 120S B 32.44 12.24

BFG Rugged Trail
P275/65R18 114T BSW 31.9 10.7 (ON 7.5)
P275/65R18 114T ORWL 32.3 10.3 (ON 7.5) T
P275/65R18 114T ORWL 31.9 10.7 (ON 7.5) F

Now, I assume 'bsw' means black sidewall..so mine are the ORWL, and I assume the F means ford oem (there are a T and F in the original equipment category).

So based on this alone, I should be fine as I'm only giong up half an inch in diameter, but about 1.5" total width...I'm guessing thats still fine based on most feedback here.

Does anyone run these exact Terra grappler AT 305/60-18 on a stock 04-08 fx4? Good to go?

side note..the terra grappler codes wear and tire codes differ from tires.com and nittos site..not sure why. measurements were all from nittos website though

I have the 305 60 18's terra grapplers on my fx4. It does have a leveling kit but that was only needed for the 35's I previously had.
The nittos are not really much bigger then stock once you get them on the truck, just alittle wider. I wouldnt hesitate it.

 

I agree. the 305/60-18's will fit fine using the OEM wheels.

 

These will fit on stock wheels with no level, without rubbing?

 

Yes, on a 04-09 F-150 4x4.

 

Im thinking about the nittos. I do haul a boat that is about 7000lbs. Does anybody haul with tires and do you or anybody will i have any problems.

thanks
