thank you for replying, no its not making any noises, tyres are the same, sometimes when your driving it seems to pull to the right,, if you hit a pot hole accidently it pulls to that direction, husband seems to think that it could be the steering rack, if there are any groves in the road it jumps about all over the place. Also do you know the correct tyre pressure for Pirelli 225/45/17 tyres please . tyre itself says 51 psi but that seems excessive. (karen)
