RWD car - front tyres wearing quicker, why?

[anonymous-user]

I've got an E220cdi (s211) which of course is RWD, all tyres were put on the car at the same time yet the fronts are nearly on the markers whilst the rears have loads of tread left, all are wearing evenly across the tread 'width'. All are the same brand (Michelin Pilot Sports), I use manufacturer specified tyre pressures and check them regularly.

In any other RWD car I've owned the front significantly outlast the rears, why the other way around, could it be down to the weight of the heavy diesel lump up front?

You go too fast into corners and are a pussy on the way out?

Maybe you've got broken suspensions or something at the front?

You're driving it backwards?

More weight over the front tyres, combined with suspension / steering setup to make the car under steer rather than over steer

you need to shift-lock on corner entry and clutch kick on exit more!

I eh 'suffer' from the same thing - 318d so all the effort and momentum but no power to complete the corner as enthusiastically as I entered!

I would have thought MB would be fairly balanced, BMW try their best to get close to 50/50, but there has been understeer dialled in to pretty much every RWD car.

If you have 4 wheel alignment done without problems, it's either just the way the car was set up, or your own driving style. If it is your driving style, then you'll have to decide to either be a little less sporty, or live with the consequences.

Get your tracking and alignment checked.

Alternatively as we all know how shameful your predicament is

1. Find a large airfield
2. Turn off the traction control
3. Brake really hard just as you turn in far too aggressively to lighten the back of the car and cause it to swing out.
4. Apply lots of throttle and opposite lock.

Apply this and you'll have those rear tyres bald in no time.

Heavy lump combined with a delicate right foot I should imagine. Assuming all the geo etc is fine of course.

Clearly what you need to remedy this situaton, is an evening of rain and a quiet roundabout.

You aren't using your right foot enough or you have 50bhp.

even with all the will in the world there is only so much you can do with a midrange diesel power (140-190 bhp) because all these things have tyre widths more suited to things with 400 bhp!
