premature tyre wear bridgestone
sent off one rear tyre to bridgestone with the usual premature tyre wear, the tyres on the car are checked weekly and are always eaxactly kept at bmw recommended pressures, they have never been run below or above those pressures and have never sufferd punctures. the car is used privately and carefully, never drived anywhere near its potential and never tracked, here is bridgestones response.
" Compression chafing was noted around the bead seat area, as well as accelerated wear to the shoulders/tread edge. This is conducive with the tyre having been run in an underinflated/overlade condition. This has placed undue stress on the carcass and caused premature failure/wear of the tyre" to cut the rest short THEY DONT WANT TO KNOW!!! I dont intend to let this drop, i certainly will not buy any more bridgestone tyres, i think like the cracked wheel saga all those suffering this wear problem should start being heard, after all at £250 a throw these tyres are not cheap |

I got around 20,000 miles out of my Bridgestone RFT's, with even wear across the tread.
Is this a Bridgestone problem, or an issue with the suspension geometry on the e92? |

whats annoying me is that they are saying the tyre has been run under pressure and overloaded when i know damn well it hasnt, therefore their diagnosis is wrong therefore it must be something else doing it, i dont think there is enough negative camber to cause that amount of wear more like the tyre is not up to the job. i now have another new set of bridgestones on the car and will monitor these VERY carefully as i dont intend to suffer this again. i have now learned my lesson and will not buy any more bridgestone tyres EVER!

First, what size tyres and what is the door shut placard pressure, for normal & loaded? Second, are you using a calibrated pressure gauge, if not, how are you sure you are accurate? I had my gauge checked against a calibrated gauge used by my BMW Dealer, just to eliminate issues with the control baseline. Third point, has the car been through a KDS alignment check, to confirm the car is in spec', for camber and rear toe? Also what kind of trips are you making? Lots of short ones? By that I mean less than about 15 miles. Why I say this, premature wear of RFTs has a lot to do with whether the tyres warm up to the more critical working pressure, not so much the 'setting' pressure that is crutial. Many of us need to run more than the normal pressure, or the wear definitely shows up as underinflated wear patterns. I've been through this learning curve for RFTs, and tyre pressures are much more critical and need of adjusting to use, than running normal rubber. Front outside wear also has a set of criteria to meet, to reduce wear, typically pressures need increasing above suggested placard settings. BTW, this is not just a Bridgestone issue, it happens to other brands as well. Highland Pete |

my e92 came with bridgestones, did just over 20k on the rears, had worn quite evenly. the fronts wore on the insides quite a bit, but looked nearly new on the outside. dont think they are very good tyres in terms of grip and am thinking of going for the ps2s next time.

I got 24k out of mine. Noticed the inside wear on the rears at 18k, but hadn't been to good at checking presures. Kept them at 0.2 bar above the stated figures (recommended by the dealer), checking regularly, and they lasted another 6k, with pretty even wear.

The problem is that bmw has put too much negative camber on the rear they must think that we are all F1 drivers and split seconds matter I took my 335i to a specialist and asked then to take some of the negative camber out the results are brill more straight line grip and on the roads (corners etc) no noticeable difference even in the wet, however tyre wear is even. JOB DONE!

just got a letter from bridgestone repeating that i have been running this tyre underinflated and overloaded. i know for a fact this is untrue, the only answer is that thetyre is faulty. in BMW car mag this month a bloke with an e92 is having the same problem, are bridgestone seriously suggesting that everyone with this problem is running round with their rear tryes underinflated. with so many people are changing to a different make, me included you would think it would be in bridgestones interest to do something to placate customers rather than lose all that business.

why do you keep changing the thread ACER... you need all your threads combining.
IT IS NOT a problem with bridgestone. All rear tyres wear this way. Due to the negative excessive camber these cars run. Coupled with hard driving will compound the problem.

Running my E91 over the BMW pressures recommendations due to maintained high speed (motorway driving) and added load being carried some of the time. Rears got 38,000 before they went across the tread. The original fronts are to be changed in the coming weeks after 51,000 miles from new. Its the inner and outer edges which are now gone. The middle still has 3mm.

BTW, I emphasis again it is not just Bridgestone tyres that wear this way. Many run-flats are run too soft, BMW and companies like Bridgestone know it. HighlandPete |

im running the pressure recommended in the manual i think its 2.8 bar, maybe the "underinflated" problem is that this is too low as i know some people have been advised to run .2 bar more. i shall try this with the new tyres. what pisses me off is bridgestones attitude especialy when they are giving the same bullshit to other people, in the past i have seen tyres that have been run underinflated and they wear the outside and inside of the tyre anf if they are overinflated they wear the middle, to waer a tyre in 20,000 miles that badly the tyre would have to be run considerably underinflated and this would be felt in the handling. anyway hasnt done them any favours as i will go for michelins from now on, never had any problems with them in the past.

I have not experienced any excessive wear and get around 15 -20 per rears which I believe is acceptable for the soft compound that Bridgestone use.
Since early 2007, I have had an E92 and an E93, I KDS the car on arrival and then at tyre change, run at 0.2 bar over recommended. I get between 15 to 20K per set of rears, which i cionsider to be fine for a UHP tyre. Bridgestone runflats are a soft compound with a very low treadwear index and unless it is all motorway driving around 15K miles of life is a respectable number. |
