I have a question - probably a dumb one - but I will ask it nevertheless.The Yokohama tyres I bought are directional. Presumably this prevents you from swapping the wheels corner to corner. However - what do I do about the spare which theoretically will only be suitable for one side of the car.Am I being thick - or what?
Not a silly question Alan. I assume from this you have bought five new tyres.You fit the spare up for the LHS of the car as the majority of punctures, damage and wear occurs on the curb side. Nails, screws etc tend to gravitate toward the gutter with the road camber and the road edge is more likely to break up than in the middle of the road.Rotation is a simple "front to rear" on the drivers' side and if you want you can introduce the spare into the mix on the passengers' side. Fit it to the front, front to rear and rear to spare.If you do have to fit the spare onto the RHS, not really a problem. Just be aware of it but it's far less of an issue than a temporary spare or a steel wheel fitted with mags. Then get the damaged tyre repaired and replace it where it was.
Must be disappointing.
Could some of the noise be caused by the 17" rims and the resulting lower profile tyres? :-\
What was interesting is that there is a section of the M42 near where I live that has a 1 mile section of concrete road which changes abruptly to tarmac. As the car moved from concrete to tarmac – or vici versa – my ears told me that there was a sudden and significant change in noise level with both tyres – the concrete being noticeably more noisy. However the decibel meter readings did not confirm this.
What I failed to do was to check the tyre pressures when the new tyres were fitted. I told the fitter to inflate all tyres to 32 psi and was too trusting.

Regarding my comment earlier about the change in noise levels as the car moves from concrete to tarmac or vici-versa - I perhaps need to explain that I am not referring to an instantaneous peak - like running over a joint on a bridge - I mean that there is a noticeable change in noise levels between the two surfaces that is made more obvious because of the sudden change from one type to another.
I'm told by a person in the know that when a car is involved in an accident the crash investigtor will check tyre pressure, assuming tyre(s) are still inflated.If they differ by more than a certain % from the manufacturers psi then that driver could be held partly to blame or even fully liable for the accident even if he is the innocent party.Anyone else have views on this?
So far a handling is concerned - I am of an age where comfort and safety are my prime concerns. Long gone are the days when I took bends on two wheels and a door handle.
