Hi all

I have had my C63 for 5 months now.

One wheel had a crack, that was welded. The repair failed after 3 weeks of me picking the car up. I complained to the dealer who paid to have it re-repaired (at my choice of place).

The re-repair failed after 2 months so I made noise to the dealer and they replaced the alloy.

That replacement alloy now has a crack in it!!!

Im sick of pumping up my tyres every week and with 500 bhp there are obvious safety concerns.

Any thoughts on what to replace them with?? Our roads are obviously not up to the stiff suspension/19inch AMG alloy combination.

Borbet has just released a new range as has OZ (but they can be soft). Zito are excellent quality, there are loads of options out there.

A mate owns a wheel shop and will be able to help

Thanks both. Reluctant to change the whole set of wheels (dealing with tyres, TPMS etc)... but I cannot see another option.

Be able to help to repair the wheel or help supply new ones? :)

Thin tyres and thin alloys are only any good stood still, crash bang crack, crash bang crack then its new tyre time.
Some one I know had a Kahn Range Rover that went through many many alloys,
welds need a skilled hand and stress relief but then are still a compromise and need a magnetic particle type inspection at least.
Personally I would want something else.

IIRC the TPMS is not in the valve but works on the rolling circumference of the wheel, tyres would just swap over

You could repair but they should have a 2 year warranty and if they crack that easily they are "not fit for purpose".

You could go down to the 18" wheel and tyre combination to have some more "give"

Think the TPMS is in the valve on the 63’s- is in mine anyway.
Not a deal breaker, there are a few UK aftermarket ones to replace at reasonable cost

Two types - active and passive - mine has active with sensors.

True, unfortunately I sourced the (new) wheel from a private individual so no recourse on that one! I have thought about dropping down a size, which I may ultimately have to do.

Can thoroughly recommend Northampton Welding for repairs. He does a fine job and can repair stuff you would think was past redemption.

Many thanks, have given them a call, they instil confidence. May try that. They cannot provide a warranty though :(

Mine is passive so no sensors in the wheels, you can buy the sensors and just bolt them into new wheels

True, its just another cost to add on.

If you go there don't be put off by the look of the place - its a proper old school place. Scruffy, stuff lying all around but its a no BS pride in their what they do place. The guy who owns it is very approachable and good at what he does.

For sure, they are often the best kind of places!

Drop down to 18s, go full on deep dished for the added zing and flair. You know you want to.

The parlous state of our roads, potholed, cracked, poorly repaired, the poor design of speed humps all massively impact the lifespan of alloys.

Drop a size and increase the sidewall ratio? - it will give you a bit more 'bump' protection.

If you notice that you (everyone) wallop a pothole, stop and take a photo of the hole - try to put something next to it to give perspective of size. Check your tyres for lumps - inc inside wall.
You can look up if potholes have been previously reported online, if it has, and you later hit it damaging tyre/wheel, then you can claim costs.

I wouldn't mind something in the matt anthracite variety but plonking down £1500+ on alloys after having just spend £3500 + on gearbox work and a coilpack for the S smarts a bit!

I do already with this, its mainly the manhole covers etc, and the general horrible state of the roads to be fair! Same issue as above with swapping the set of wheels, may do it at a later date.

If you do change the wheels, it may be worthwhile looking at aftermarket forged alloys, inherently stronger than cast alloys (which is what the vast majority of OEM alloys are, as it's a cheaper process).
Aftermarket new can still often cheaper than OEM second hand too.

These were £200 and change per corner.
