My 1984 Bronco's front tires always wear more on the outside. Usually when I rotate them I move them straight back on the same side. But I was thinking this time I would leave them on the front and switch sides by taking them off the rims and remounting them so that the worn sides (currently the outside) would now be on the inside.The tires would now be on the opposite side of the vehicle and still turning the same direction. Is this a good idea? The tires are Lt 235/75 15's

 

Check the toe setting. Too much toe-in will wear the outside edge of the tires.

 

Sounds like an alignment concern, either toe or camber is out. Darrell

 

I have had it checked before, but they always say " it's a Ford, that's just the way the tires wear on them. Nothing you can do about it." Looking at it from the front the tires have a very noticeable angle like this / \

 

time to find a new alignment guy!!!!!!!!!!! They use to say the same thing about the Ford Twin I-Beam, but they can be adjusted....it takes a little bit of work versus the slep boys 30 minute special!

 

How often do you rotate tires? On a 4WD they recommend every 5000 miles or every 3000 with a limited slip diff. They will wear fairly good if you can do them that often. If not they will wear on the outer edge from scuffing when turning.

 

Sorry I do not have an owners manual handy, but where did that come from? Specifically the limited slip part of your statement.

 

Not sure of where I picked that info up. After 40 years driving 4WD'S and being a ASE Master Auto and Master Truck mechanic and having been to more training sessions than I can count. Can't remember where I picked that info up.

 

Is that after backing up and parking? If so the suspension tends to do that and will straighten up more when the vehicle is moved forward a few feet. If that isn't after backing up then you could have a number of problems including sacked springs, worn pivot bushings, worn ball joints, or a poor alignment tech. Also if the truck has a lift the lift brackets could be lose or have the wrong springs installed, or the alignment tech neglected to install the necessary camber alignment bushings for the lift kit.

 

I do not recall ever seeing the 3000 mile rotation interval for a limited-slip equipped vehicle. Learn something new every day
