2018 F-150 max tire size with 2” lift
I have a 2018 F-150 4 x 4 super crew cab. I am adding a 2 inch spacer to the front, add a leaf and new shocks to the back because I like some rake. I do not want to remove my crash bars ! Does anyone know what size tire I can go to? My wheels are 17” vision raptor wheels with a +25 mm offset . The guy at the shop said the crash bars would need to be removed to put on 285 75/17 tires. These tires are 33.86 inches in diameter. The stock ones are 31.7” and it seems like there’s enough space to fit the larger ones w/o touching crash bars. Anybody have knowledge on this? Thank you |

Here's an answer. Short version "no".
Incidentally--and because this is in the Off-Road forum--if you're doing any significant off-roading, strut spacers aren't a great idea. You don't have to search long to find photos of demolished front suspension from wheeling with pucks. I eventually replaced them with leveling struts because they maintain factory down travel. Aside from that, the OEM struts are just garbage. |
I am currently running a VSP 2" solid aluminum spacers on my 2018 F150 FX4. I am also running 2018 Raptor wheels with 315/70R17 BFG TA KO2 tires with zero rubbing, zero trimming and crash bars intact. The tires sit almost perfectly flush with the fenders and I still have full turning radius. Perfect setup in my opinion.

I have Fox Coilovers (got just over 2 inches of lift) and fit a set of 285/70R18 Nitto Ridge Grappler tires (33.98 inches) on my stock wheels and plenty of clearance. Granted the tires are not very wide, but they are lighter in weight and the ride is awesome.

I agree, this looks amazing, I am sure it functions amazing and there are ZERO compromises for the 99% you are not off road
However, it has done great at the California sand dunes, the Arizona white mountains and Arizona desert when hitting established trails that don’t require spinning wheels to climb things. I mostly use this truck to get my family around and tow dedicated off road toys. I wasn’t building a Raptor or rock crawler competitor, just something with a bit more ground clearance that looks good as well. If I needed this truck to perform at a higher level off road I would probably run the Icon suspension or the Roush Fox setup, but this works for my purposes. |

I had 2" spacers with my 305/65-18 KO2s, which BFG specs as 33.6" diameter, and I ran them with lots of clearance and no other modifications. See my build thread for crash bar photos and level specs. I also ran a full-length AAL kit from AutoSpring and replaced the 1-1/4" stock blocks with 1" poly blocks. Incidentally--and because this is in the Off-Road forum--if you're doing any significant off-roading, strut spacers aren't a great idea. You don't have to search long to find photos of demolished front suspension from wheeling with pucks. I eventually replaced them with leveling struts because they maintain factory down travel. Aside from that, the OEM struts are just garbage. On my Frontier, if you lifted a front tire off the ground, the UCA would contact the coil bucket. I had a spacer that provided 2" of lift, the contact cut downward travel by about half an inch, never happened on road and rarely offroad. In the Tacoma world, those guys are massively against spacers but if I lift my wife's truck, thats what it will be...the truck will never go off road. I'd go with 5100's but all I keep reading is that they rust within a year up here. |
