Can anyone help please. I've just bought a 1.9CDTi SRi ('05 plate) which has Vauxhall 16" alloys on. They are 10 spoke (5 paired spokes) pattern.
Not being an expert I thought they looked right on the car but staff at my local tyre dealer tell me that they are Astra wheels.
My SatNav tells me that the speedo is under-reading by 8 or 9 mph when driving so I am suspicious.
Should the car be on 16" or 17" wheels?
