Hi guys, In the middle of getting my Z roadworthy and was just looking for a good tyre and wheel combo to put on. Im in VIC and I know thee laws on wheels and modifications are quite strict. What are my options when going for the inspection? Is it best to find stockies and then change them after or find a decent pair now and hope they pass? :rofl: Thanks Jason
As a general rule/ guide but still subject to others, you can generally go an inch wider or larger than a stock wheel/rim (or vice versa). Of course the wheel must not foul or extend beyond the body line but this is easy to achieve if the offset is taken into account. Not many people will advise going above legal limits on a forum, therefore majority of advice will be to get the right size combo to begin with or go stock and track down the right ones later. I tend to think a staggered set is a better choice myself but its really just a preference and it has its drawbacks in that you cannot rotate them, but if your wheels are setup up correctly, then the wear should still be even anyway. Forget all the crap/shit like spacers etc. - just get the right rim to begin with!
From VicRoads Guide to Modifications for Motor Vehicles (2011) Tyre and rim substitution may be carried out without certification within the specified limits (13.2). The width of any replacement rim must not be more than 25mm greater than the widest wheel specified by the vehicle manufacturer for that model or vehicle series (13.3.2). The overall diameter of any replacement rim and tyre must not be more than 15mm greater than the largest diameter tyre specified by the manufacturer for that model or vehicle series (13.3.2). The maximum allowable track increase is 25mm for the front axle and 25mm for the rear axle (13.3.2). If you intend to modify the vehicle beyond the guidelines listed above then yes you should attend the inspection with stock wheels fitted. If however your choice of wheels is compliant with the guidelines then you shouldn't have any problems. All of the above is freely available from VicRoads, suggest you google "vic roads modification tyre" and the document mentioned above will be the first hit.
