Hello everyone, when I got my 2018 f250 (april with about 24,000)I noticed that my front right tire had a little chop on the edge and the drivers side had some on the inner edge. I took the truck to get it aligned and have a tire rotation done. The rears wear moved to fronts and they were perfectly flat. I’ve put about 2000 miles on it since the alignment and the drivers side is wearing perfect but I noticed the passenger side is starting to have a little chop to it. If I run my fingers over the outer block toward the back(red circle) the the back tread catches my finger. I wanted to know if this is just normal from a solid front axle or if I should look into some issue?
wear on both outer edges is suspect of too much toe in
wear on both inner edges is suspect of too much toe out
interestingly...since you have wear on one inner edge and one outer edge....suspect would be the rear is out of alignment....
you can measure the rear trailing egde to the front trailing edge on the driver side and compare to the pax side....im suspecting 1/4 or more of a difference.
if that is the case...there are sliding block pin holders that can be added to make the correction.
sometimes the play in your pinion arm bolts and the play in the rear block studs is enough to cuase the misalignment.....these bolts can be partially loosened....then you put a crank able cargo strap on the side that is longer....wrap the strap around the front axle on the long side...then the rear axle on the long side. jack up the truck using 4 jacks to take the weight .. crank the strap until both sides measure the same...then tighten all the bolts to spec.
Thanks for the info! I've measured the center of the wheel front to back on both sides and they are pretty much right on. I measured toe across the front wheels and the front tires are leaned toward the middle of the truck about a 1/4" compared to the back so I think that's correct too. I am going to try airing my tires down to 55 all around and see if that helps. I had the tires aired up to the same psi as when I tow. I'm hoping that maybe the edge wasn't making good contact.
I'll do that and see what I can come up with. I did have it aligned at the Ford dealership on June 17th, but I know that doesn't mean a whole lot. I also may have not done a good job of describing the amount of toe. Its a quarter inch total, so an 1/8" per wheel.
So I took my truck by the dealer after work last night to have them look at the tire. I'm not 100% sure that I believe them, but they said they think it's from lack of rotations. When I bought the truck I don't think they had ever rotated the tires on it. The back tires were nice and square. The rears are now on the front have started the little bit of heel-toe wear. He didn't seem to think that it's an issue to worry about and printed off my alignment sheet that was done 2000ish miles ago. Everything on the sheet looked good.
I just checked mine. I did a lift kit a few hundred miles ago and the ubolts stretch.
Drivers side 469 mm from rear trailing edge to rear edge where the locking hub dial is. Pax side was 473mm.
adjusted the pax side to 470mm
then checked both and the pax side was 470mm and drivers side changed to 471mm.
adjusted drivers side to 470mm. Checked them both and they were both 470mm.
When you say rear trailing edge/front trailing edge, can you elaborate on where you're taking your measurements from? Im following what your saying about comparing them. In my head Im thinking your measuring from the back bottom of the fender to the hub lock, and from the front edge of the fender to the hub lock.
Thanks for helping!
Shocks are still the shock ones for now. The steering stabilizer was changed about 2000 miles ago. I normally run tire pressure at 53 all the way around and 60 up front and 65 in the back when I pull my travel trailer. I’m not 100% sure what the stock tire pressure is because the door tag was for 17” wheels and it has the 275/65r20 from a lariat on it now.
So here is the alignment sheet for when I had it done. I played with tire pressure but the gee toe wear is still there only on the passenger side. I had the Ford dealer do the alignment, but it looks like some of the settings weren’t even changed. I spoke to the service manager and he said the tire wear seemed normal but couldn’t explain why the drivers side isn’t wearing the same way.

on top of everything already said . this is classic incorrect inflation (not by much, but i say over inflation) and the wear is actually caused by heat from scrubbing going down the road. Air pressure, alignment, worn components etc. you need to play with raising tire pressure a 2 or 3 lbs and drive hundred miles. ideally you want a flat even contact patch with a just a hint of outer tread not touching ground. this is after everything is checked for adjustment..
example empty i run 65 up front and 60 in rears. but each vehicle is different based on actual weight on each tire. accurate weight on all four corners will net you the correct psi for each tire using the inflation tables at the tires manufacturer page... is this side of truck heavier or lighter than the other side? sounds like all the hard stuff is done, . again weigh the truck on all four corners as it it normally driven.
its alot for a light duty vehicle, but long tire life can be achieved. i have a very heavy motorhome and correct pressures based on the actual weight is paramount to maximum tire life, performance and safety
