F.A.O anyone with Rear tyres + inside edge wear

330cdsport · 08-21-2009, 10:49 AM

This is a very common problem/feature for E9x rear tyres unfortunately.

scottishpete · 08-21-2009, 02:48 PM

I was talking with chairman of BMWCC at weekend and he has been talking with someone at bridgestone who siad they are going to start paying out for the tyres apparantly

Dont hold me to that tho

Tunna_uk · 08-21-2009, 05:37 PM

The tyre wear on the inside of all the pictures on this thread in my opinion is down to negative camber. Its what makes the cars handle so well in many situations, the trade off is inside edge wear. My old E36 had the same tyre wear. I think BMW have always been setup like this.
Only experimenting with different tyres can sometimes give a longer tyre life. (Harder compounds etc)
At the end of the day its a drivers car and set up as one

Same on my 6 aswell - one of the rear tyres has a lot of wear on the inside edge. I was going to chase the dealer up about it. Is there any point?

They do have a lot of negative camber - had the car parked "above" me at the weekend (high level car park) and really noticed it.

If they wear quickly (2k miles so far with no sign of excess wear) it's an excuse to get new tyres! TBH I think the small size and high profile (45s) of my RFTs are actually a huge benefit - happy for anyone to try my car and see what they think because I don't seem to be having anywhere near as major issues as those with bigger/lower profile rubber. I think the tallness helps no end.

acerboo · 11-12-2009, 04:53 PM

does this wear seem to be particular to bridgestones or is it happening to all makes

dxb335d · 11-12-2009, 04:57 PM

All makes for me.

acerboo · 11-12-2009, 05:02 PM

trying to establish if bridgestones are more prone to it as i think there is a fundamental problem with them, bridgestone told me my rear tyres show premature wear on the insides due to being run underinflated and overladen, i knoe for fact this is utter crap so that only leaves the tyres at fault, obviously they want to admit to this, one thing i know for sure i will never buy bridgestones again ever.

The problem buddy, is the excessive negative camber our cars run. Not the tyres construction or pressures.

I currently have 1.8mm. The outside 5mm.

Does not help Im always nailing it which = squatting which makes the camber worse.

It is not just Bridgestone, other brands do it as well. If fact rear inner wear is not a new problem for BMW, just made worse by run-flat tyres, the bigger the rims, the more the torque, the worse it seems to be.

Very often it is due to UNDERINFLATION, BMW and the tyre boys know it. That's why many recommend inflating by about 0.2 bar over placard spec's, for normal use. Short trips and cold running can be just as bad for the tyres as driving hard.

khanuk · 11-12-2009, 08:53 PM

i hav a e93 cab an i jus realised rear tyre inner wear..its a common fault an nothing to do wid the bridgestone runflats... i went to a local 4 wheel alignment garage an he sorted it out i had too much negative camber an the rear wheels were toein too much out... he aligned the rear an the front were already in line wid the rear wen he aligned the rear so fronts didnt need alignin... its cost me 50quid an car is bang on... dealers said 420quid.. another said 120 per hour an cud take up too 3 hours... an f**k kds cuz bmw dealers sett the camber to the cars requirements...

khanuk · 11-12-2009, 08:59 PM

i had same problem... but all sorted... how much did it cost you??? i got more postive camber on mine an toed the rear wheels in... now its bang on an steering is straight tooooo....

Actually it's more of a problem on non runflats. The re-unforced sidewalks of te runflats help them wear more evenly compared to non runflats

Interesting, I'd like to come back on this one when I've a little more time, as I've had the opposite experience and would like to discuss and illustrate it.

BTW, what normal tyres have you had wear more severely than run-flats?

HighlandPete · 11-13-2009, 08:12 AM

On a broader level, let's look at all the forces involved here, rather than just be hung up on alignment. Lots of tyre shops look at tyre wear and declare the geometry is all wrong, "way out mate", "too much camber" and "too much toe-in", offer to realign, etc., etc.

Do we not think BMW set up the cars to best performance? Remember that a BMW can likely be used by just the driver at speeds up to 150 - 155mph (where legal) and need to drive straight and accurate. KDS alignment typically shows no error, alignment is in BMW tolerances. Also remember that if BMW could just change the alignment specification, to get rid of this strange tyre wear, don't we think they would do it? Change the spec' for each car that goes on a KDS rig. More to it than that.

+1 its a design feature for handling and cornering set up.

My car is an E91 SE, standard suspension with 17” wheels. My original tyres, Bridgestone Potenza RFTs, 225x45 R17 all corners. My rear tyres showed the first signs of inner camber wear within about 8k miles. I replaced the wheels with another wheel set this time 8”/8.5” x 17” staggered setup with Goodyear Eagle F1 GS-D3s. The rear ends up with a wider wheel, 255x40 R17. During the last couple of years both wheel sets have been on the car. The Bridgestone’s have covered about 15k miles, the Goodyear’s over 20k miles. Tyre pressure set to balance centre and inner edge wear. Both on the same geometry settings, driving the same roads and in a similar manner.

If anything, you’d expect the Goodyear’s to have more inner wear, but not so. In my case the harder walled RFT increased the wear pattern.

Bridgestone at 8 - 9k miles

Bridgestone at 15k miles

Goodyear at 20k miles, slightly more wear on the inside. (Left side of picture)

My E39 540i on M-tech suspension and 17x9” rims and Dunlop SP 2000E tyres would give about 20k miles on the rear, before change time with about 3mm across the tyre and just losing the inner edge.

I’m sure the 19” tyre has something to do with how this wear pattern reverses the wear rate from RFT to normal rubber.

RichJ · 01-15-2010, 09:02 AM

Do people who are running non runflat tyres on 19inch rims, find that they wear much quicker compared with the runflats i.e bridgestone?

Em135eye · 01-15-2010, 09:43 AM

My rear RFTs had worn much more on the inside on my 17" 225s.

Got the alignment checked, stuck non RFTs on and will keep a closer eye on pressures.

acerboo · 01-15-2010, 12:26 PM

mine are knackered at 20,000 even though i have driven the car gently, sent the tyre off to bridgestone who said i had run it under pressure and over loaded, this is absolute bullshit as i check pressures every week and keep the them spot on, they also gave someone else exactly the same lame excuse, so it seems all the owners of e92's on 19's bridgestones are running round with their rear tyres with low pressure. ive never heard such cods wallop.

dib669 · 01-24-2010, 10:48 AM

My wife's 330i has gone through three sets of RE050A* rears in 15000 miles (as well as four rear 225M rims). Each set has had the same problem described here - the inner edge (about 10mm wide) down (or nearly down) to the carcass with about 5 - 6mm rubber left over the rest of the tyre. I've heard that Bridgestone have changed the compound on the inner edge of the RE050s to try to compensate for whatever's happening. Anyone else heard this? The car, much as I like it, is going soon for this reason.
