Split rim alloys - why?

21 posts in this topic

Some manufacturers offer split rim alloy wheels, where the wheel is (I think) two piece and seured by little hexagonal bolt things.

They look really smart, but what actually is the point?

And if you undo all the little bolt things, would they fall apart?

cant see the point myself. Way too fussy designwise too.

Over fussy and they charge more.

Why would you want to undo the little bolts......unless it's not your car!

Isn't it incase you want to change the outer rim for deeper dishes later? Also if it corrodes, you can change a bit of it rather than bin the whole wheel? Not sure if the extra effort and price is worth it though.

But some do look real nice.

Split rims were design for 2 reasons.

1st one is that there was once an age when sidewalls of tyres were not 'flexible' enough to be squeezed over the wheel lip without damage to the side wall or the wheel.

So you could split the rim place each half on the tyre and then rebuild the wheel without any issues of tyre fracture.

This was a problem with sports performance cars with (then) huge tyres in the 70's

Additionally the design allows for new rims should one get damaged, buckled etc.

Was it not becasue they used to be limited as to the size of single casting they could make one 'solid type'wheel from and still retain structural integrity?

I'll bet you can't actually buy new rims for them though. grin.gif

Good to know there's (sort of) a reason for them though. 169144-ok.gif

In racing terms I've always believed split rims are actually a stronger design and less likely to crack, it also allows the flexibility of different materials as RR has illustrated above. I'm looking to source a set of magnesium split rims for the mini to reduce the sprung weight on each corner, magnesium for weight reduction, split to add strength to a soft material. 169144-ok.gif

Split Rim Rebuilds

Split Rim wheels or three piece wheels have in the past generally been very difficult to refurbish. However technology is changing and many bolted wheels, such as the Jaguar XKR range of wheels, are now repairable.

We stock replacement Split rim outer rims, stainless steel wheel trims, titanium and alloy wheel bolts and studs and rim screws.

Wicked Wheels are the first choice for Jaguar dealers throughout the UK.

Here's a link for some 10" mini ones

Minispeed split rims

Your find a heap of split rim wheels still used of huge HGV's the reason being that super sized tyres cannot be fitted in the conventional tyre iron + muscle way.

Also a split rim can take far better force pressure caused by both load and high PSi setting of tyre 169144-ok.gif
