wheels aligned once - do they need doing again?

[trace1967]

Had a puncture on rear tyre last week, got new toyo tyre and put alloy and tyre back on, does this mean I need a re-alignment of all four wheels. Had it done last july.

No. Tyres make no difference to alignment as long as they are the same size.

Decent tyres shouldn't anyway - the GT radials which I'm getting rid of soon are quite stuffed, out of round/flat spotted etc - I had those on the front and kingstars (also cheap crap but fairly new when I got the wheels) on the back. Rotated tyres front<>rear to wear the GT radials out faster and the steering wheel has been off centre ever since.

Whilst the tyres won't (shouldn't) make any difference, it is worth getting the alignment checked regularly (yearly) IMO as it doesn't take much to move it from the sweet spot.

Tyre pressures?

well since i had the alloy wheel and tyre put on I now have a slight vibration on the steering at 70mph. What caused that then?

No definetly not.

The wheel could have been balanced incorrectly.

Pressures fine and dandy and car still tracks straight and handles right, just the steering wheel is off-centre. Think I'll get it realigned once I have some new tyres on it, its just enough to annoy me.

it was a local garage who fitted it. do they balance wheel whe putting the tyre on the alloy?
they took ten mins to fit tyre to alloy wheel then put it on the car using the jack.
