well looks like a trip to the dealer

[cmills]

A while back I posted about my truck wearing the outer edge of the right front tire (probably the outer 1/3), well I took it and had the alignment checked and everything was fine. So I thought that maybe it was a tire problem so I swapped the front tires, and it appears to be wearing the right tire again just like before. And now it pulls to the left most of the time. I assume this is because I put the worn tire on that side, but it is weird because it would track straight before when it was on the right side, even though it was wearing the outer edge of the tire. Does anyone have any ideas? Thanks

Sorry, this is on my 2014 3500 dually

Your from end is in "SPEC". Align to 1/32" toe in and all will be well. Went thru this with my 11.

what problem were you having?

what problem were you having?

Outer edge wearing mostly on one tire. Took it to my local guy I have known for 30 years and that is how he aligned it. I had taken it to a dealer to align, I thought they did something but another 5K later the tires e=were getting worse. My guy said they had not done a thing because the toe in was at 1/4" and was within Chryslers specs.

I will be taking my new 15 in to be "properly" aligned soon at the independent shop I trust.

When i say it was wearing, I don't mean a little, I'm telling you it was quite a bit and at least the outer 1/3 of the tire probably closer to the outer 1/2. could the toe being out cause that much wear? And only on one tire?

A toe adjustment will not fix that. You either have tire pull (not likely since you changed them), or an uneven caster problem with the front axle.

1/4" toe in will do that that is way too much. every Dodge and Ram that I have owned has had too much toe in from the factory. The sweet spot seems to be 1/32-1/8" at that setting you'll find the tires wearing/ feathering on both the outside and the in side. Remember our front tires will show much more wear on the out sides as there are more forces from steering on the outsides. As for the truck pulling after swapping the tire from side to side with that much wear on it your going to get that. It's better to swap it with on of the rear tires. I had steel wheels on my dually and would swap all the tires around every 10,000 miles It wasn't un common for me to get 80-90,000 miles out of a set by doing the full truck rotation. It was a pain as the inside wheels would go to the front the outside rears swapped to the inside and the ones coming off the front would become the out side on the rear. With steel wheels they were all the same it was just a matter of swapping them from side to side to get the right off set where it was needed. Back then the theory was to never X radal tires. Keep the always rotating the same way.
Back to alignments I have found that our trucks come with a bit too much caster. Camber is the setting (which is not adjustable on our solid axel 4x4 trucks ) which effects the pulling feeling as your driving down the road. Caster is the adjustment that effects the return to center after you come out of a turn. How ever if you think of a shopping cart going across a hill caster will want to follow the hill ( down the hill) not the route across that you want to drive. I have found some ofour trucks to have 5-7 degrees of caster. if the truck has a leveling kit that number goes up to 7-9 degrees as lifting the truck causes the axel to rotate. One would think that more caster is a good thing but it causes the truck to want to follow the crown of the road more. Pulling right in the right lane and left in the left lane. Not really pulling in the center lane. Some of this pulling is ok as should you have a medical issue the last thing you'd want is the truck to wonder in to on coming traffic. How ever too much will and does cause fatuge (sp?). It makes that long trip that much longer fighting the wheel all the time. The sweet spot that I have found is 3-4 degrees caster. or as close as you can get to it. By the way I went back to the shop manual for the 89 that I use to own the toe in setting they called for way back then was 1/32-1/8" checked at the inside bead to inside bead of the wheel at the same location off the ground front to back. the Front measurement will be the lower one by 1/32-1/8" hope this helps

Ok, thanks. But wouldn't it cause wear on both tires

 

[cmills]

I'm going to try to post a pic of the alignment sheet, so you guys can see what you think

 

[RustyJC]

It depends on the roads you drive on. Typically, because of the crown in the center of the road, you're steering left into the crown. This would result in more wear on the right front tire. The greater the crown, the greater this effect will be.

here you go, see what you think

 

[sag2]

The two wear angles are toe and camber. Caster is not a wear angle. It looks like the total toe is correct but the right side is out of spec.

Exactly. A conscientious alignment guy would have set each front wheel at 0.10* for a total toe of 0.20*-----dead in the center of specs.

 

[EDankievitch]

On all the trucks I have seen and worked on too much toe in always causes more wear on one tire. More so than the other tire, but both tires will have wear on the out sides if too much toe in. And on the insides if too much toe out.

 

[Cummins12V98]

My guy said because of the roads where I live one would wear more than the other. The factory wants these trucks to track straight that's why they have 1/4" toe in.

 

[cmills]

I guess I just never thought the the toe being off would cause as severe as wear as I have and only on one tire but If you guys really think it is a toe issue, tell me what I should have them set the right and left toe at and I will take it and have it done.

 

[cmills]

I'm thinking about taking it and having the toe set. When you said 1/32" toe in, is that total toe?
