Cracked Alloys - options?

Recommended Posts

Sorry if this subject has been covered many times before - I did a search and didn't find any consensus of opinion.

 

I've just failed the MOT for two cracks on both rear alloys.  Car is a 535d currently running 18" MVII with Goodyear NCT 5 RFT.  Been quoted £75 per wheel plus VAT but I'm keen to switch to 19" Spiders and ditch the run flats but finding a set of spiders with no damage or welds isn't easy.  Moreover, with the state of the roads, I'm guessing future cracks are highly likely even if I run normal tyres?

 

Just wondered if anyone has fitted different style wheels that may be stronger than the original E60 options?  Are all BMW alloys of this era prone to cracks?  BMW continue to fit RFT to new vehicles and wondered if newer alloys have been strengthened to cater for UK roads?  If so I'd consider a newer style wheel and spacers if it meant the wheel wasn't prone to cracking!

 

Any suggestions please?

Spiders are the worst of the lot IIRC

 

Do your alloys need to be genuine BMW?

 

Personally I’d stay away from run flat tyres; buy some decent alloys from the folks at BMAutosport and fit normal, decent tyres

I was advised by the company that refurbed my Spiders to increase to 41 psi all round to help support the wheel after three of them needed straightening. 

 

Thanks but this sounds like a compromise to a known problem, would prefer to stay away from Spiders.

No, don't have to be genuine but not a fan of some of the clearly aftermarket rims available. I was wondering if the M5 alloys of the same era in both 19" and 20" are prone to the same issues as Spiders?

As far as I'm aware; yes they are

 

Sounds like you're stumped!

They're these via BMAutosport: http://www.bmautosport.co.uk/showroom/product_info.php/new-avant-garde-m359-spoke-alloys-hyper-silver-deeper-concave-105-rear-p-4686?cPath=51_24_147_35_239

 

Personally, with alloys, unless OEM, I'd always buy new. However, your car & your budget

 

They're also the wrong offset for your 5; you'll need 12/15mm spacers as well

 

The guys at BMAutosport know what they're doing/talking about as well; couldn't recommend them highly enough

 

Re the 2nd set of alloys, not to my taste, but always horses for courses when it comes to stuff like this ;)

If you're thinking 19s or 20 inch wheels that advice could apply to your chosen wheels. Speak to some specialists for advice, not just someone on ebay flogging wheels.

 They look nice, dished CSL style wheels look great imo

Good luck - i gave up with spiders, every set i looked at had at least one wheel with welding repairs or flatspots.

 

Plenty of bad roads & speed bumps where i live...

 

i remember having similar problems with staggered MV2's for my old E46 when i wanted a set.

Thanks for all of the comments.

 

If money was no object then I would have bought these:

....think they really suit the car and look OEM but cost £2,500 for the wheels.  My car may be the same colour but can't justify such an outlay.

 

Then I saw these advertised on Gumtree:

Almost identical to the CSL style Deviant suggested and just £500 for the wheels and tyres and all tyres have over 6mm of tread.  At this price I couldn't say no and managed to get them couriered next day for just £60 using Paisley Freight.

 

I've fitted them now and as others have said countless times before running normal tyres rather than runflats has made a huge improvement to the ride, especially at this size.  Just shows how hard a ride my old runflats were even with 40 profile.
