Nice comment about the spare tyre... It's very difficult to get the spare tyre off the picasso anyway because the holding cage for it underneath the car is rather worn. On the new grand picasso there is no spare tyre because where the spare tyre would normally go there are two extra seats. So I could in theory do away with the spare tyre and simply buy a foam kit to keep in the car like the new car comes with. Great idea.
I checked all the tyre pressures last night and noticed that both rear tyres were down a bit, both front and back are meant to be 33psi and none were over 30, so we'll see what difference that makes today. Also I've taken off the wheel trims for now because they stick out and the plain uncovered wheels don't. I have plenty of spare corex (that plastic cardboard like stuff) board at work that I will acquire to cover them.
