Tire wear and dim lights

An alignment problem causes it. You rotated once when the wear was there on one tyre but not as apparent because it was not as worn, now with more wear both tyres are showing the effects.

Get an alignment - suspension check done before you do anything else. (Note a suspension problem can cause an alignment issue). No all alignment problems will cause a noticeable handling problem.

Alignment.

Shimmy/wobbling is usually balancing, not alignment.

Alignment is usually pulling to one side although that's hard to really determine since most roads have a "crown" to them and slant slighty towards the outside for drainage which would cause your car to pull to the shoulder even with good alignment.

Get new tires first and then get an alignment (if the tire place does not do both...many tire stores are tires only and not alignment).

Weak alternator probably. Although I would also expect the alternator/battery light on the dash to stay on for longer than normal after starting in this case. Is that happening as well? My A2 GTI does this on colder/wetter mornings. It's not an immediate cause for alarm or replacement but eventually your alternator might go.

Good point. You can't do a proper alignment with bad tyres.

I fear my original message may have been misleading. I should have said don't buy tyres and have the alignment some time later, the alignment needs to be done at the same time or you will just damage the new tyres.

Excellent advice, all. Thank you. Tires and alignment coming up. Alternator on the watch.
