Inner tyre wear on E92 3 series

[x5x3]

All four tyres now replaced due to inner wear - still plenty of middle tread left which is quite irritating.

Is this a 3 series "feature"?

And, does anyone know what needs to be done to fix/prevent it?

Tyre pressures my friend. I too have an E92. What a cracking car dont you think?

I assume you are still running factory runflats. I too have suffered tyre wear quite quickly.

It is because the run-flats are very sensitive to pressures. Wrong pressure and they wear rapidly.

Check your tyres, inflate/deflate as neccessary and they should be ok.

I thought I was ok on the pressures - maybe the local garage meter is out?

I have a 335d also and yes it is a superb car - and I say that as a diesel hater!

Personally, I always get my local dealer to do my pressures. Garage forecourt air dispensers are notorious for not being regularly checked/calibrated, so pressures being quoted on the readout could be wrong. Your tyre wear seems unusual. You could also get a 4 wheel laser alignment done too.

I was never a fan of the derv, but this car is sublime. So planted and also very fast even as standard. Lives with E46 M3's all day long on the road. Re-map and you will pull past!

Go to a local halfords and the like and get a digital one, then you can check it whenever you want.

I found with my old e46 that if I went for the higher recommended pressure (the one for high speed with load) that my mpg was much better.

might be worth checking around on that with the runflats - if anything my pressures were probably high after a summer holiday run

I've read about this a few times before. The recurring answer seems to be that it's caused by the run-flat tyres. Basically there is little or no 'give' in the sidewall so the edges of the tyres are subjected to more force than the middle meaning that the contact patch wears unevenly. A lot of poeple with BMWs like to switch tyres to non-run-flat examples the first time they require renewal.
