    The stock tyres on the VN were 185 75 14 , 634 mm diameter tyre , 14 x 6 inch wheel

    On those 16 x 7 inch Commodore stock wheels you now have (which should be the same offset as the stock VN wheels) I would use a tyre -- 205 55 16. 632 mm diameter . Typically 91 load rating in that size. (A 205 50 16 is too small in diameter and typically a lower load rating)

    The 205 55 16 will sit 10 mm closer to the suspension than the original stock tyres in 185 75 14 but there will be room to fit. If in doubt checking inside clearance is easy enough.

    225/50X16 is the required size for clearance....Load rating must be 92 or greater

    225/55X16 will hit the spring base and 205/55X16 will be under load rated for the car

    215/60r 16, 225/50r16 or 225/55r16 will all be ok. 215/60r16 will be the cheapest option.

    Tried 225/55X16 on my VC (same strut) and they hit the spring base....I suspect the 215/60X16 will do the same, even though I haven't tried

    These were tried with VXSS rims (currently fitted to the car) and 16X8 CSA Prowlers

    215/65/16 clears the spring base on a vs, throws speedo out on the rear though.
    16x7 vs ss rim

    How much clearance do you have with the fender?

    Seems like you need wheels with less offset.

    Pick up a set of factory BMW wheels off Gumtree.

    That's weird, can't explain why your having issues with your vc but I've been in the tyre industry 12 years now & never had an issue fitting those size tyres on 1st, 2nd or 3rd gen commodores including my own Vk with 16x8 hdt momos

    To the original poster, I recommend you take your wheels to your local tyre joint & ask for their advice.

    Been in the tyre trade for over 20 years.....Have tried plenty of Commodores, pre VR with 225/55X16 and had the same issue...Hit the base of the spring plate..

    I actually forgot to mention....The struts fitted to my VC are from a VP....Only changed the top bearing plate, because the VP ones were shot and the VC ones were good...Otherwise, it would have been a straight swap over

    Offset isn't the issue....The VX wheels currently fitted to my VC is closer to the inner guard, than the previous 16X8 prowlers fitted....Still have the same problem....225/55X16 hit the spring base of the strut

    Offset is the issue,put 50 series tyres on your 48p rims or get the correct 30/35p offset rims for your car. Late model generic commodore rims sit 18mm closer to the suspension (48p vs 30p) than the average old wheel. 16 x 8 SV5000 rims are 30p with 225 50 tyres and will fit and look tough. Lower the offset ,deeper the dish,better the look.

    Well, please explain why when I put 225/55X16 on both the CSA Prowlers AND the VX rims, they hit the base of the spring, when the offset of the VX rims is 48P and the Prowlers are 30P?

    You've got your VX rims a little mixed up
    VX S models had the 16" rims
    VX SS had 17" rims

    VX SS Rims

    VX S Rims......These were also fitted to the VU S ute

    Yes I have the model of the car wrong.....The rims fitted to the car pictured are the rims I currently have fitted, not the ones you have pictured....And I realise it is a VT pictured, but my rims are VX rims

    I agree that they are not VX rims.
    I was going to point this out but didn't want to start an argument with someone who has 20 + years in the tyre trade :)
    Are these the same rims that were fitted to the VT S as well ? I'm thinking that they are but not 100% sure.

    I believe so. Holden had a habit of fitting the previous model's SS rims to the next model's S.....see VR SS vs VS S as an example.

    Rims are slightly different....There are 6 spokes instead of the 5, and the spokes are slightly flatter and wider than these pictured....3 out of the 6 spokes are wider than the other 3 and have a 7cm X 2 cm "hole" inbetween the spokes starting near the top edge of the rim and go towards the centre...The other 3 spokes have the have gapping similar to the VS SS rims.... I believe the centre caps interchange though.

    I just looked at the picture I posted and realise I pictured the wrong rims...These are the ones....So you can compare the 2 different rims now and understand what I was trying to explain
