F-150 Online Member Faces Issues Fitting 35″ Tires on His Ride
Will a 12th gen Ford F-150 accommodate 35×12.50″ tires with a level and nothing else? Well, maybe.
On of the most common questions we see here in the F-150 Online Forums relates, of course, to tire size. Everybody wants to run the biggest tire they can, whether that be on a stock, leveled, or lifted F-150. Of course, the answer to these questions is never easy. The size tire you can fit on your truck is going to vary based on the type of tire you choose, wheel offset, and of course, what model year the pickup is. So it’s really not a surprise that forum member DCinMI recently faced some troubles when trying to squeeze 35s on his 12th gen. Despite having success with similar setups in the past.
“In the past, my buddy and I have both put 35×12.50” tires on our leveled trucks with stock wheels. Both (2004 & 2006) were F-150 models and had no issues. Yesterday, I went to get 295/70R18 Atturo Trail Blade XTs put on my 2013 Lariat Super Crew (with a 2″ level and OEM 18’s). The guy came out and told me they were too wide. I told him that doesn’t seem possible, noting my past experience. But he said the sidewall was touching the upper control arm without even tightening the lug nuts. I wasn’t allowed to go look for myself, so I had to take his word. Any thoughts/opinions or facts on this? Anyone else running 295s with a 2″ level on OEM wheels? I remain absolutely unconvinced that those 295s were too wide.”
Right off the bat, fellow member JackandJanet points out that all tires, regardless of size, aren’t created equally.
“Since you are changing tire brands, it is possible the section width is larger on the Atturo Trail Blades. Most tire manufacturers post charts that list the widths of their various tires. Have you looked for that data for the Atturo tires and the ones you currently have on your truck? I think that would answer your question. But I suspect the tire guy was probably telling you the truth. He’s in the business of selling tires and would likely gladly mount those unless there was some problem that could lead to future problems that would force him to take them back (after damage) and put on replacements (at his cost).”
Unfortunately, the OP states that Atturo doesn’t list these specs on its web site. But as JackandJill also points out, his new tires seem to be significantly wider than the old 275s.
“I just re-read your first post and notice you currently have 275/70R18 tires mounted. The 275 number is the width of the tire in millimeters, or 27.5 centimeters. Now, there are EXACTLY 2.54 centimeters in an inch. so your current tires should be 10.827″ wide. The ones you want to mount have a width of 29.5 cm, which is 11.614″ wide. So, they would be about 0.4″ closer to your inside fenderwell and the outside fender wall. Maybe this would be OK on the rear axle, but on the front, if you turn the wheels lock to lock, would the tire perhaps rub the inner wall?”
In addition, we are comparing two different generations of F-150 here. So as glc points out, wheel offset could also be an issue, in addition to location of parts like the control arms and crash bar.
“The offset of the 18″ wheels may be different than the 20″ wheels. That has to be taken into consideration, along with the wheel and tire width.”
Thus, this thread has left us curious. So we want to know – are you or anyone you know running a 35″ tire on your 12th gen F-150? Head over here and let us (and the OP) know!
