I bought a 2006 F350 Harley Davidson Edition, I noticed after a while the front passenger tire stuck out about an inch from the fender, non of the other tires are like this. Further more, that same tire is showing signs of uneven wear kinda like cupping. Any Ideas on how I can fix this ? Thanks in advance

 

Has it ever been wrecked?
How many miles on the truck?

An inch is a fair amount. Alignment/wear may account for some of the difference or possible impact damage, cab alignment etc. Generally with age/wear tends to create negative camber or would angle the top of the tires inward.

A simple and quick 'thrust alignment' check,,

Take some heavy nylon masons string or similiar,, tie it to the rear axle housing fairly close to the inner wheel area.

Making sure the steering and front wheels are centered (steering wheel is in dead centered position) then extending the sting out beyond the front tires a few feet or more.

Pull the string around the rear tire from behind 'centered' to the tire/wheel front face. Basically against the rear tires sidewall starting at the 9:00 & crossing at the 3:00 position.

Now using the string as a sight guage (string still at the 9:00 position on the rear tire sidewall) slowly move the string "pulled tight" from a foot or less 'away' from the front tires sidewall face to 'now' just barely touching the rear tires sidewall meaning contact at 9:00 from being pulled tight, and it's sighted in 3:00 position from being angled in a bit until it 'just barely touches'.

With the rear tire 'points of contact' now made at 9 & 3:00,, and the string pulled straight and taunt it should make contact with the front tire sidewall position at its 9:00 position with the string remaining straight with no bends over the rear sidewall (3:00), or leaving the rear 3:00 position and making an air gap to make the fronts 9:00 contact point. Taking 'toe' correction into consideration, generally you don't see the slight discrepancy over the trucks long wheelbase. It may take a few checks should the string bounce, but if held tight generally very little string deviation. The front tire 3:00 position generally will indication a few degrees of 'toe in' meaning you'll see a slight air gap in the string to the inside.

A rough check, may/may not prove out an 1" offset, but fairly accurate to check for 4 wheel or thrust alignment. Quite a few things could cause a wheel/tire offset difference..

 

Thanks for your reply, No the truck was never wrecked according to the carfax anyways, and the mileage is 179,000. I will try the string trick this weekend and then probably have to make an alignment appt. Thanks for the help Hayapower
