The OEM steel wheels that I have along with my Rostyles both have a total width of 166mm, backspace of 132mm and an offset of 49mm. Since 1987 I have been running 205 section tyres, with clearance between the D post on the o/s being closer than the n/s.
So, if I were to go to a wider aftermarket wheel but continue to run the same width tyre, then in order to offer the same support to the bearings, uni joints etc and to minimise possible steering changes, would I not need to run wheels with the same backspace? The offset will reduce as the wheels width increases naturally, although if I were to run the same offset, then the backspace must increase which brings the tyre in closer to the suspension components.
Here in N.S.W, the track in order to remain legal must not increase by more than 25mm.
Chris, I would especially welcome your views on this matter.
