Thread: Compomotive Rims

Depends on age also. They changed the Alloy to a stronger one at some point.

Well I'm guessing not as many as Discovery 3 / 4 wheels and well I'm sure they fail too, I've never seen a failed one, but I have had one of these Compomotive wheels with the same inner crack going across it.

I was surprised and disappointed that my Compomotive buckled the way it did. Whether or not another alloy wheel would of done the same is purely conjecture.
The impact from hitting the washaway was negligible - to the point that i wasnt even sure i fully hit it. That maybe says more for the impressiveness of the D4 suspension than anything else. In fact, if it hadn't of been for the severe grinding as my flattened wheel scrapped over the caliper, i would of thought nothing of it...

I did think about buying a set of Compomotives but decided against. The total expence of tyres plus rims and the losses selling the original tyres and rims just didn't add up to me. For what we do I think a good set of Maxxis or other 19" tyre will suffice.
Saying that I may look at the 18" steel rims some have said about in a few months after reading any feedback from others.

Yeah I’m in a similar place. The 19” has sufficed for the level of off-road I do with the fam.

I reckon the steel wheels are the way to go....BUT
Do they come in white? or another colour, I'm unsure how the black wheels will look on your very pretty (ok ok "pristine") looking white D4

My only concern with the steel wheels is the weight. I've got a set of Compomotives and now Tuff Ants also. Even on the much lighter Compomotives - running my STT (275/65/18) there was a noticeable increase in unsprung weight. This was evident in just everyday driving. When I eventually mount the STT's to the steels, this will result in a much heavier wheel, and I suspect even more of a noticeable difference. I also think there will be a much higher chance of driveline failure (ie CV's) because of the shock loading of a heavier spinning wheel suddenly stopping. Having said that, everythings a compromise and for me i couldn't justify the expense of 2 sets of Compomotives.

What is your baseline for sensing more weight? Tyre type and diameter has a greater affect than the wheel.
For example, I noticed this swapping between Compo/KO2 265/60/18 and OEM LR/GY 255/55/19

The Tuffant weighs 5kg more than the Compomotive or LR rim but that weight is distributed between the disc and rim sections of the wheel. The further away from centre the more effect extra weight will have on rotational inertia and so I don't agree that some proportion of the 5kg will increase shock loading failure risk much. There's a greater risk factor in the larger diameter & heavier tyre which puts that extra weight significantly further from rotational centre, especially with a 275/65/18
