Hi guys, im looking into putting some 20inch rims on my 2003 Vy Spac.
I was wondering if they are a legal size and if they would void my insurance?
I have the stock FE2 at the moment but i find theres sooo much space between the tyre and gaurd with the stock 17 inch rims. Would the 20inch rim close the gap or will it just look like im 4WD-ing?
I was looking at either of these 2:

would they fit?
Cheers guys! :surprise:
Daniel is incorrect. FE2 was fitted to your series 2 VY S. Fe2 was standard on all VY series 2 SS, S, and SV8 sedans.
The tyre to guard gap is larger on the FE2 cars for the VY and VX models than it was on the VT model.
If you fit 20 inch rims and tyres you must :
- retain the minimum tyre load rating stipulated for your car on the tyre placard. If you put a lower than minimum load rated tyre on the car it is illegal.
AND
- ensure speedo accuracy is maintained which means the tyre diameter of the replacement tyre MUST be the same or very close to the diameter of the standard 235 45 17 size tyre fitted to your car ex factory. These are approx 645 mm in diameter which means that to retain speedo accuracy you will need to find a 20 inch tyre that fits the rim in approx 645 mm diameter.
You will not reduce the gap to the guards with a 20 inch riim and tyre unless you put on a much larger diameter tyre. However, this will throw out speedo accuracy (it will under read)and render the tyres illegal.
You reduce the tyre to guard gap by lowering the suspension with lower springs - not by fitting illegal oversize tyres.
Many of the 20 inch set ups I have seen on VYs have larger diameter tyres to achieve the minimum load rating needed. This renders the speedo reading inaccurate. Top get the correct width/diameter you need a 30 profile tyre on 20 inch rims. If you increase the rim size you must reduce the tyre profile to compensate, ie. 17 inch 45 profile , 18 inch 40 profile , 19 inch 35 profile, 20 inch 30 profile.
If you run a 19 inch on the VY you will have no trouble getting the correct tyre to cover both the load rating and correct diameter to retain speedo accuracy.
235 35 19 diam approx 647 mm
245 35 19 diam approx 655 mm
To achieve the minimum load rating on a 20 inch rim (8 or 8.5 inches wide) you will probably need a 245 30 20 tyre. It will depend on the brand though and you need to check the load ratings carefully. This will also give you a tyre diameter of about 655 mm which is very close.
With respect to vehicle insurance, you MUST advise your insurance company of a change of wheel from the standard type or size. This is a vehicle modification and you are required to disclose all vehicle modifications to your insurer. If not the insurer has the right to deny any claims you might make in future whether or not the claim was affected by or related to the modification. When you have decided what changes you want contact the insurance company to ensure they will continue to cover you if you make the change. Then disclose the modification to the insurance company when it is done and make sure this is acknowledged in writing.
