Probably a stupid question...
Do you need to use different bolts when changing 15" wheels to 17" wheels ?
Reason I ask is that when I took delivery of my 17" alloys they gave me some bolts too but they did not fit my tyre iron, So I just used the existing bolts.
A thought just occured to me that they may be camber correcting bolts and could explain why ive been suffering the car pulling to one side
Ive had the tracking checked and it was 1 degree out, ive swapped the tyres to opposite corners, ive checked tyre pressures, ive checked power steering fluid levels
The last thing I did was to switch the wheels to opposite corners (all 4) took it for a quick test drive and it seemed better but did pull twice but not as much as usual. (It was also the same stretch of road so it could be the road)
Anyway.... the bolts ?
