cracked rim
« on: 17 August 2022, 20:10:20 »

I removed a wheel to clean off all the old goo from previous balance weights. When it was all nice & clean I found this ...  :(

I've ordered a used rim off eBay. I think I'll get the cracked rim welded as a spare for when I find another cracked rim  :y

Big rims, ultra low profile tyres, potholes = cracked rims.  :(

They're low profile, but wouldn't say they're ultra low. 265/45 x 20
I can't remember now what profile I had on my Omega .... 235/45 x 17 ??? if so, the wall is actually taller on the ML that it was on the Omega.
I've had it suggested that straddling speed 'pillows' is the problem  :-\

Straddling speed pillows (everyone does it, all the time) might be bad for your alignment, by forcing the wheels outwards from the bottom, but I really can't see how it would crack a rim like that. The tyre would deform, but not enough to bust the rim, surely? If it really was the case, I'm sure we'd see a lot more of this.
Just follow any vehicle and you'll see them doing it, it's a natural compensation to stop one side of the vehicle taking a hit.

You could always slow right down, but nobody does that either  ;D

There are half a dozen or so pairs of speed humps on the main drag through our estate ... I do try not to take the pi$$ but 20mph isn't easy  ::). I straddle the pillows in the Merc but go between them in the Smart!  :y :y

The weakest part of an alloy rim is the inner edge of the rim where there is no strength from the spokes. Straddling 'pillows' puts unnecessary strain on the weakest part of the rim. If the profile is such that the tyre absorbs the deforming, no problem, but low profile tyres can result, in the worse case scenario, damage to the rim, which is then usually only noticed when balancing replacement tyres.
I'd rather drive between two of them with one wheel, and drive over the top of the adjacent 'pillow' with the other wheel, which is a pain.
I hate speed humps, 'pillows', chicanes and all forms of traffic calming measures with a passion, as in reality, they are vary rarely well thought out in their planning.

That makes it sound pervy  :D

Basically negotiating those square speed humps with a wheel either side. Which ends up running the inner edge of the wheel over a smaller crown than the whole hump, but still higher than the road surface where the outer edge of the wheel is. Effectively this puts the full weight of the vehicle on the inner edge of wheel as you drive it over the front and rear edge of the speed hump. Doing this at a pace smacks the inner rim into what is usually a straight edge,  which significantly increases the loading on the wheel in a manner that it cannot support.

Fair enough, but I wouldn't say 120mm, as on Andy's car, is low profile.

Even with the Omega I tend to drive full wheel over the top of 1 and let the other go between on flat ground.Yes a real PITA as requires compliance from oncoming traffic and at the speed I go over them tends to really p*** over anything behind but with the weight I carry in the boot exhaust bottoms out if I try and straddle them.

I hate any form of traffic calming as it just encourages most to use them like a slalom course.
