Tony Posted October 27, 2006 Report Share Posted October 27, 2006 As most know the RFT (run flat tyre) is armoured so that i can 'run flat'. To cope with this aggressive sidewall the suspension is down-graded to ensure a comfortable ride..... That's all well and good but there is an unadvertised issue. The RFT when hitting a bump/pot-hole does not absorb the impact within the sidewall like conventional tyres so the energy is transported through the wheel to the down rated coils. Whats missing from the RFT development is the wheel itself (no development) so the consequence is this...... The lack of absorption now directly aimed at the wheel is cracking them..... wim says: It's pants, this BMW rim costs over £500 and is now scrap thanks to the compulsory pothole we cannot avoid on a day-to-day basis... All new developments have a cost but i feel the cost to the owner regarding the RFT is unexceptable...... Quote Link to comment Share on other sites More sharing options...
scorps Posted October 27, 2006 Report Share Posted October 27, 2006 Obviously the manufacturer of the wheels know they are for RFT so you would think they would know this could be a problem. Or is it just me Quote Link to comment Share on other sites More sharing options...

Or is it just me Reading between the lines i think they assumed the new suspension would belay this problem....If they have got it all wrong then this will cost someone a lot of money.... and i wonder who?

scorps Posted October 27, 2006 Report Share Posted October 27, 2006 Have they heard of testing Quote Link to comment Share on other sites More sharing options...
Tony Posted October 27, 2006 Author Report Share Posted October 27, 2006 Have they heard of testing I honestly don't know.... probably on simulators and test tracks, in the real world there is an obvious problem, this is the third wheel i have seen at STS cracked over the last few weeks so i feel a RFT virus is inevitable Quote Link to comment Share on other sites More sharing options...
scorps Posted October 27, 2006 Report Share Posted October 27, 2006 The owner could sue the council......i've done that b4. Quote Link to comment Share on other sites More sharing options...
Tony Posted October 27, 2006 Author Report Share Posted October 27, 2006 The owner could sue the council......i've done that b4. Indeed but my problem is with the product.. Since the wheel is not 'flat-spotted' meaning the entire inner dish was damaged then the impact must have been reasonably confined to the bead area, this is quite worrying.

Tony..do you know if those are cast or forged? Considering the price I would expect the latter, but the crack says otherwise. Quote Link to comment Share on other sites More sharing options...

Tony..do you know if those are cast or forged? Considering the price I would expect the latter, but the crack says otherwise. To my knowledge the wheel is designed for the standard tyre... the only addition is the pressure sender fitted to the valve, this is to make the driver aware he/she has a deflated tyre.. 'cast or forged' add BMW to the rim then the price is whatever... Quote Link to comment Share on other sites More sharing options...

BTW, I haven't heard back from Eibach, Germany on the UK/US spring issue so have sent them an email chaser... Quote Link to comment Share on other sites More sharing options...

With the tyre/wheel configuration you have this scary topic does not apply to you (thankfully).... On the Coil side of things, the feed back i received displayed much distress for the approved fitment you have. If you don't get an answer soon then i will pass the link on to you, but appreciate this would complicate things. Quote Link to comment Share on other sites More sharing options...

No harm being done at the moment though as I'm driving around on the other side of the pond in a Ford Escape and the 250 will remain stationary for at least another 3 weeks Quote Link to comment Share on other sites More sharing options...
