Wheel alignment after rotation???

[jay see]

So I rotated my wheels the other day and now it pulls.
I didn't think that a alignment would be necessary after a rotation or I'm I missing something.

Wouldn't think a rotation would affect the alignment, check to see if the air pressures are the same.

That's what I thought. It shouldn't.

Have checked pressure, all same.

Thinking of putting them back how they were to see what difference it makes if any, or just get it aligned again.

The wear pattern differences between the tyres is the only thing I can think of thats causing it. Doing a wheel alignment only adjusts the toe in/ toe out and is measured from the centre of the wheel. That wouldn't change due to changing tyres around. Surely???

That's why I was thinking of putting them back how they were, to see if it would be straight.
That's the only thing that makes sense tyre wear
Will see if I can be farked when I get up.

Did you swap front to back (right rear to right front) or side to side?. If you changed side to side the tire direction of rotation will be reversed & could affect handling. Had a set of Hankooks years ago that did not like being spun the opposite way.

A bloke told me that tyres gain a memory and don't like rotating the other way if left on the same side for a long period, I thought he was blowing wind up my freckle until I read that!

I have heard that before.
Tyres have done approximately 7k.

Good article on Tire Conicity (misaligned belts) & first tire rotation, worth a read. http://www.agcoauto.com/content/news/p2_articleid/181

Might be a faulty tire.

If its a wear pattern(& perhaps different tyre pressure) issue, then after driving as it is now for a while, the pull should hopefully correct itself.
More than half of the time, the vehicle pulling to the side on a flat stretch & a standard wheel alignment are not related, 'cos camber and caster angles are rarely touched during a normal wheel alignment and those angles don't usually get massively affected by typical rotation, afaik, unless of course, the wear pattern and pressure difference between them are significant.

I have a feeling, if you match the pressures of the tyres & drive it for a while, it might self correct.

Of course, it's possible one of the rear wheels that end up at the front may have a fault developed inside the meat of the tyre.
I've had that experience ages ago with an old Jackaroo that I used to drive ages ago. A front tyre started distorting bit by bit and I had to replace both front tyres.
Examine the front tyres with a ruler across to see whether the ground face is curved in a funny way or whether there are any minor bumps on them that can't be seen easily with naked eyes.

If the wheel alignment is sightly off, you will see uneven tyre wear on front ones in no time since you're driving the Patrol all the time. Somehow, I don't think that is the case in yours.

I think that "tyre memory" explanation has good points behind it.
