Two years ago I had new tyre's fitted and noticed there was ware at the edges.
The Getz tyres are normally at 32psi, but the maximum pressure of the tyres is 44psi.
so I deducted the 32 from the 44 leaving 12 divided that by 2 then added the 32 giving a pressure of 38psi.
The car is driving no different and I am waiting to see how the tyres are warring.
Our last tank of diesel was around 44mpg and that is driving around Paphos, we have just started to use the air con now.
