I've just put my car back into T&C because it was pulling to the left. They reckon that everything was spot on but had noticed that i had different tyres on the front (Same size, different manufacturer). They reckon that the different tread patterns can cause the car to steer strangley IE. pulling to one side so they swapped the front pair with the rear pair. It does seem to have 'cured' the problem, but I'm a bit sceptical as to wether this would be true or not....

Incidently, one tyre is a Falken and the other is a P Zero.

Any thoughts on the abbove guys????

 

would not have thought that different tyres of the same size would make a jot of difference.

Things that usually effect are
Tracking out-clipping a curb, pothole, etc
brake pads rubbing on the disk
bent subframe/suspension

If one of the tryres is already tracked - already worn on one edge this may cause it as well.

Yes different tread patterns will affect that, definately on the front.

Different tyres have different characteristics, which also change from car to car, for example bridgestone s02 great on car A crap on car B...

FYI Directional tyres are worse for tracking on the road compared to non-directional tyres.

 

Yes it does make a difference. Some time ago there even was a warning not to mix the same Pirelli tyres from different factories/countries.
