If i put 17" streetpack alloys on my zetec s tdci will my road tax go up from £20?

No :)

You sure? As im sure that was what the dealership guy said was the reason why the street pack was ni longer available on the zetec s tdci to keep emmisions down?

Whilst that is true what you do to the car after it has been registered with the DVLA will not affect the tax band.

Shouldn't do. I've got the older 90ps TDCi with Streetpack wheels factory fitted & my tax is £20 for the year.

buying any non-standard wheels will not effect your RFL, but should you inform your insurance company will effect your insurance premium, not informing them may void your policy should you have an accident.

unless you do an engine transplant lol - but i think wheels will be exempt

You’ll need to tax your vehicle at your nearest DVLA local office. Write the new details in section seven of your Registration Certificate.

DVLA will need written evidence of any changes to engine number and cylinder capacity (cc). This can be the receipt for the new engine' date=' or written evidence from the manufacturer, insurance company or garage that carried out the change.
