if the wheels are originally 3 piece then yes you can swap on wider inner or outer shells no problems. It gets tricky when the wheels are originally welded 3 piece or even just 2 piece. There's a chap by the name of Gavin Bateman who makes wider shells, but I would say the likes of Arrow wheels would be able to do the same.

Aftermarket welded wheels .MUST have a cert. If they were legally done, then they will have a cert supplied If no cert papers then "maybe" they have been stamped with a traceable/trackable marking

What about widened steel wheels,not Arrow type wheels,but ordinary wheels like on a early Holden etc.

Isnt the wheelbase the distance between front and rear wheel,the track is between front wheels,i think.

ANY aftermarket welded wheels must be certed for street use.
Factory welded wheels are automatically certed & stamped by the manufacturer's

Apparently,they are knocking cars on them now,they are becoming a trend,so they say,that is my local garage.

yeah i guess it depends on your wof guy. well i've googled this a few times for nz info in the past and found that if they are done by someone who can weld (a professional crowd) and you have a receipt this will be ok. also, most seem to think that cutting the centre out and putting it in a 'new' off the shelf wheel is the best and safest option, with the old 'band' welded in method not as favoured.

Yea that makes sense.

there are a couple of places in nz that are recognised for this work. i can't remember who they are just now but an hour or two on goggle will work.

jolly wide wheels widened me escort wheels in circa '91 from about 5.5" to 7.5" with a steel band and then powder coated. can't see why they shouldn't still be legal

They would be , but, that's a certified manufacturer, not just a widened set of dodgy alloys.

i think you mean steel wheels not alloys.

The welder that widens rims MUST be a certified/qualified welder for the rims to be legal for road usage & it's HIS job on the line if the rims break.
Either way, the modded rimsare still certified by a qualified person regardlessof who makes them (factory/ welder/home built) The problem with s/h modded rims is proving they have been certified by the relevant qualified tradesman

Some of the problems with some home non certed welded rims is . The weld splitting & coming apart. Bits of steel splintering off & puncturing the tyre /tube Warping causing speed wobbles & or busting wheel bearings/ stub axles from vibration
