Split Rim wheels
Why?
Do split rim wheels have any particular benefits/advantage over an ordinary wheel?
Why do they split into 2 and 3 pieces? Is it for multi-adjustability or some other reason?
I've never actually fully understood why they split. There must be a good reason but its not obvious to me........

3 piece splitrims are split into:
outer rim
patterned center
inner rim
Prime advantage is you can change the inner / outer rims to get wide wheels / more offset....
Second advantage is the bling factor....
Not sure on how 2 pieces split, but would imagine that 2 of the above would be cast as a single item (probably a complete rim with the centre then
bolted in)

The other reason is they can be fixed if you've had an off?
If you bend the rim, you can take them apart and fit a new one. Inside or outside, depending on the damage.

Yep..no need to replace the whole wheel - just the bits that are damaged...

So, the rim and the centre are made of different strengths of material. The rim is actually designed to fold on impact and can be replaced instead of
the whole wheel.
So basically, its just the bling factor on vehicles other than rally/off road cars.............

Also, isn't. it to do with the fact that the parts making up split rims can be forged rather than cast, thus allowing them to be stronger and so
lighter?

Yep.
As an aside, If you've ever watched American Hotrod when they make their custom wheels, they make welded 2 piece wheels - the rims are
manufacturered to a given width, and the centres are machined from billet. They then heat the rim up and insert the centre
Once cooled, they weld the centre in place.

Repairability is the keyword. We use them for hotrod racing so that when you hit the wall (3ft concrete) and the outer rim gets torn it's
easier/cheaper to repair.

Are the seperate pieces readily available from specialists - and are they cheap enough?

twas about £60-80 for a mate of mines outer half when he knackered them at a race.
his were expensive (8's and 10's), but most of the money went on the magnesium centre lock centres.

Isn't insurance dearer for split rims - I get the impression that insurance companies feel they are more likely to be involved in an accident.

As far as I am aware the major advantage of multi piece wheels is the weight saving, part replacement is just an added advantage.

You also get a bit more caliper clearance as the spun rims are thinner than those on cast wheels.

i dont know much about split rims but last time at Mac#1 they had a set of 13" image wheels in. I couldnt believe how light they were even with
tyres on. That must be a big advantage on a race car.

I'm sure it's image one's the BIL has on the hot rod 10"wide jobbies and they're not that heavy at all.

The ultimate in split rims.
Found these at the autosport show.
Carbonfibre rim with alloy centre they were unbelievably light but not very locost the guy said there where going to be around £1000 a wheel.
Nice tho.

Could you really fit tyres to those carbon rims without damaging them?
