cracking alloy wheels

[ajlsl600]

Never had one. But roads are worst I see in 50 Yr. So prob will be seen more often. We should be able to seek compensation from the state, we pay e. To use the f roads 27 billion in fuel taxes, 7 billion in Rd tax, 12 billion spent on roads, uh?????

You can claim compensation from local authorities in certain circumstances. But guess who pays ultimately in the end? The tax payer. It's about time manufacturers came up with wheel and tyre combinations which can cope with the condition of roads and normal usage. As others have stated 5 cracked wheels in a short space of time - something was very wrong there.

My car sat on the drive for a week then a week later crack appeared didn't even use car so claiming from council is not an option

Not many road damage claims from councils are successful mainly due to the fact that if the pothole has already been notified to the council and is waiting for repair any subsequent claim is disallowed so a less than 10% chance of a payout - it’s a license to keep roads in disrepair really - we vote these people in….

Don't want to claim from council. I DON'T PAY TAX TO THEM, I PAY TO GOV, THEY DISPERSE AS THEY SEE FIT , I want to claim off gov they can take matter up with their subbies (councils) if they see fit. From rough search fuel tax receipts are in front of 26 billion and car tax in front of 7bn I saw that 2021 the gov spent 12bn on roads. THEY have our cash not the council.

Interested to understand which parts of the wheel can crack depending on the catalyst i.e. where would the wheel crack if due to a pothole, speed bump, run flats etc.?

I replaced my run-flats earlier in March for a set of 'normal' tyres and hadn't driven my car for a couple of days. The last drive was un-noteworthy with no potholes etc. encountered. Yet entering my car, it told me again that one of my tyre pressures were low and the repair centre advised that the wheel was cracked on the inside rim.. I couldn't see it myself but did see the bubbles at what appeared to be a weld line. It was a feint straight line and there was another one opposite. I didn't see any loss in integrity but bubbles were forming between the rubber the inner alloy rim. The tyre was fine...
I drove it home and no loss in pressure and am hesitating to take it back for welding tomorrow..

Inside edge is always the most common.

If you were to cut through the middle of your wheel and then look at it cut side on you'd see a “squared off” letter “C”
The upright of the “C” is the face of the wheel and the top and bottom the wheel width.
Now with large rims >18” and wide wheels >255 any force on the inside edge is a long way from the face where the only support is. This leads to bends and for harsh impacts cracks on the inside edge.

Not sure if the rim is cracked after all but will get an opinion from the expert on Thursday.... whilst I'm there, perhaps I will treat myself...

Don’t let @SmartAmg see those wheels…

Ooo'er I've come over all funny.

I knew I had seen those rims somewhere before.... Palm Springs... where else

This is a typical crack on the inner edge of a 20in AMG turbine wheel

Thank you, I appreciate the image which looks similar to what we noted except for where the crack in the image stops short and mine was edge to edge. However, we were outside in the thunderstorm when looking and hopefully it gets resolved tomorrow. Thanks for the good idea as well. I will see if I can get a photograph beforehand too.

Providing the crack is no more than 25mm most wheel specialists will do a weld repair and when done it was so well dressed you couldn’t see the repair

First-time Merc owner, also new here. Acquired a nice E400 Convertible through a private sale 18 months ago. Love the car but boy do I get through wheels and tyres, several of each already.

My motoring comprising local low-speed (20mph limits everywhere) and occasional motorway journeys. Previous cars include BMW, Porsche, Lotus, Ferrari and BMW Mini. Never damaged a wheel and seldom a tyre before in decades of motoring.

Concluding that these wheels and the runflats are a very bad combination, far too fragile for a heavy car.

Can’t afford to keep replacing at this rate, well beyond any ‘natural consumable rate’, so looking for knowledgeable practical reccos for replacing and cutting my losses. Type of wheel, runflat vs conventional tyres with or not, whether to inject some kind of leak sealant…

No ‘witty’ / humorous comments, please. Thanks.

Hello and welcome,

Switch to smaller rims if you can and don’t straddle speed bumps as it puts all the strain on unsupported inside edge of the wheel - this bends and cracks them.
Also try and avoid potholes and slow down on bad surfaces.

Cracked Wheels can be repaired and refinished.

Get rid of the runflats, they put even more stress through the wheels as there is little flex in the sidewalls. Put a can of goop in the boot just in case.

As @Blobcat said never straddle speed bumps (Pillows), one wheel should go in between and one over it.

I take it you have 20" wheels on? If so you could go down to 19" wheels with normal tyres on

The roads here in Blackpool are terrible...I have standard AMG alloys that have all been repaired at some point and I've had to replace one completely.
Mine are 18"....I've been tempted by some 19" after market ones and could also get 20" I've been told but I ruled those out as being too big.

 

[rayhennig]

It's not the vehicle that's the problem, it's the carp roads.

I agree, those carp roads always strike me as a bit fishy!!!
