front tire wear

Just checking if anyone's having the same issue my front tire wear got to about mid life and started eating away the outer edge quicker. Tire shop confirmed balancing are tracking are all ok another friend with an E91 and another with E87 have the same issue is this a know pattern. Or does it come down to driving style? Running on RFT 205/55/16 Continentals. Stock suspension.


Thanks

same here...on all my previous sets, the outer edge for the fronts seemed to be wearing quicker ....

maybe try increasing the negative camber...

Same on mine - even with mainly straight line motorway driving and pressures maintained at manufacturer specified pressures. I am told it is due to the standard suspension setup.

I've read somewhere on this forum that the OEM suspension alignment for the 335 doesn't have enough negative camber, BMW maybe tried to overcompensate. When i get my car aligned next time i'll tell them to use M3 data. This increases neg camber and apparantly reduces understeer.

Not too sure of how much to believe that, but i'm definitely going to try it.

Is the SE set up the same as the M sport? I was wondering if the above problems
were mainly on the M sport models? If they are set up differently it might be
worthwhile having the M sport models changed to the SE configuration. What do
you think?

Its yr run flats. Loads of posts on this. Its because the side walls are so stiff. I had this issue until i went to non rfts. Even wear ever since and didnt even get the tracking done!

This.

Much more prevalent on the 18"/19" RFTs but the same principle applies.

Thanks guys changing tires this wknd was going to get non RFT as they provide a better ride if this will change the wear pattern more reason to switch.

Same issue on my 2011 328xi: fronts had outside edge wear and had 3mm tread while rears still had 5mm and no edge wear. Still running Continental RFTs.
I have a twisty rural commute and am aggressive on the turns. Seems like high speed turns is the common issue here.
I swapped the same side front and rear wheels so I can get use out of the tires for 5 more months before getting non RFTs.

Here is a quote straight from the BMW TIS:

"Tyres wear down over the course of their usage. The level of wear depends heavily on the driving style of the driver. Other influencing factors are the road surface and types of road (straight / winding), the mean ambient temperature and the drive concept of the vehicle.

Tyres fitted to high performance vehicles that are often driven at high speeds primarily wear down in the centre of the tyre tread. This wear comes about through the slight increase in the diameter of the tyre at the centre of the contact area, which is caused by the strong centrifugal forces.

In particular, this pattern of wear can be seen on the tyres on the drive axle, since the tyres are subject to slip due to the drive. This slip amounts to approx 1%, at 100 km/h (62 mph), but as much as 3% at180 km/h (112 mph). When the degree of slip increases threefold as above, the degree of wear actually increases by a factor of nine!

The tyres fitted on the front axle of a vehicle show above all things wear at the outer edge of the contact area. Front tyres are subjected to particularly strong lateral forces when cornering. This stems on the one hand from the steering geometry, on the other hand from the fact that (in the majority of vehicles) the weight of the engine exerts a load on the front axle."

Same here

...and they tramlined like erm... a tram. Hated them - put non-runflats on all round. Much better.
Mine wore really heavy on outerwall and destroyed 2 perfectly good tyres - outer tread 0-1mm. Middle 4mm. Happened so fast only noticed when it started to tramline......Had tracking checked when new tyres fitted only very slightly out, and in his opinion shouldnt have been noticeable. Tyre pressures were as per specification etc can only put it down to the tyre.
