tyre pressures

Dear All

I have BMW E46 318i SE Year 2000. After a recent service the guy stated that my tyres (Goodyear 225/40R 18 92W) were all under inflated. On checking the tyre pressures they were all set at 3.0 (bars) after the service.

According the the handbook for everyday use with just the driver in the car the pressures should be 2.0 (bars) all round.

Is this the case?? or is the service guy correct????

Secondly, all of my tyres are due replacement as they are all down to the minimum legal level of tread, but I have noticed that both rear tyres are worn more on the inside edge. Does this mean that the rear wheel need
re-tracking or is this normal ??

Kindest regards

2.2 bar. You may have an alignment issue causing uneven tread wear. I guess you phrase that as re-tracking. I'mm thinking too much negative camber which is common on these cars.

With that tire profile you should have around 2.4-3.0 bars. One should always check for tire wear and adjust the pressure accordingly. 3 bars is more hard on bumbs and 2.4 is more comfortable, its your decision. Also check the pressure with 2 or 3 different gauges, they very well may show totally different numbers. 2.0-2.2 is just too low in my opinion.

edit: And yeah, get the rear looked at.

The correct tyre pressures should be on a label on the drivers door jam.
