A friend of mine picked up a bit of a banger and it has 1 directional tyre and 1 non-directional on the front.
The car pulls to 1 side, even after tracking etc has been done and the garage said it was because of the different tyres.
Is that true, would it make the car do that?
Do they even make non-directional tyres any more? May be worth looking how old it is and replacing it anyway, you can usually decipher the age from a serial number or look for hardening or cracking of the sidewall.. AFAIK tyres over a certain age are no longer able to be sold anymore , rubber deteriorates over time.
