Tyre stepping/sawtoothing

Over the past couple of months I've been trying to diagnose a noisy rear
wheel bearing. The noise was quite loud but I couldn't detect any wear
and my local indy garage couldn't either. They suggested it might be
worth swapping the tyres round and although sceptical, I eventually did.
The result was instant. Noisy rear end is now noisy front end and if
anything, noisier than before. Now that its just in front of me, I'm
able to pinpoint the noise to the left front (formerly fitted to left
rear). After a bit of googling and looking at the tyre carefully, I can
see I've got stepping/sawtoothing on the inside edge.
So a couple of questions. Obviously, something is amiss with the rear
wheel alignment but the last time I had new tyres fitted, I had an
alignment check which was fine. Would a four wheel alignment check be
better? I didn't think anything on the rear was adjustable.
Secondly, now this stepped tyre is on the front, what is the chance of
the stepped area wearing down normally and the noise reducing. The tyre
is only half worn with about 8-10k miles remaining and I don't want to
throw it away but it is incredibly noisy.
Car is Focus 2.0 TDCi with Uniroyal Rainsport 2 all round. 120k miles on
the clock.

help, but never cures it. I've found different tyres behave differently.
I doubt the odd pattern will disappear on the front.

like noise could be due to delamination of the layers under the tread. And
that it is very difficult to diagnose by inspection. The poster has
demonstrated technical competence in other matters.
I recently had symptoms as you describe which moved when I swapped tyres
around. The tyres had done 30k, still had about 3mm on and had no sign of
sawtoothing. I know tyres get noisier as they age (and Michelin Energy seem
to age particularly badly) and one of the pair seemed more noticeable...
fact or hypochondria?

I had a Nissan Cherry that had done that, but the tyre gets quite hot.

Nope, the tyre in question is visibly stepped on the inner tyre blocks.

replace with a different brand. shame really as the Rainsports are great
tyres IME.
I might try putting the stepped tyre back onto the rear where the noise
didn't bother me as much but thinking about it, it will wear out quicker
on the front and I can replace it sooner.

They never can, completely. My leon has had an alignment check/adjust,
and it is fine. It sawtoothed the winter tyres, and the cheapy
directionals is came with, but Conti SC3 seem to be OK.

I'd have to get them swapped on the rims as they are directional treads.

Yes, stepping does cause loud tyre noise. Its a well known phenomena.

Turn it round on the wheel.
