330i e90 tyre wear

[Andy70]

Hi guys just a quickie, my partners car has excessive wear on the outside of both front tyres, plenty of meat in the middle and the car runs in a straight line, so I believe tracking is ok, oh they are fun flats by the way if that makes any difference, any ideas please? cheers

Just because the car drives straight doesn't mean the alignment is straight. Get it checked out.

Unlikely, but it could have an equal amount of toe in/out on each side making it drive straight but excessively wearing the tyres.

These really benefit from a proper four wheel alignment on a Hunter machine or similar. Mine felt fine when I bought it, but I had it aligned at first tyre change and it drove like a different car!

[Andy70]

ok, cheers guys, I'll get them looked at thanks

Yup my E91 did this too. Got the alignment done, really minor adjustments but no more outer edge tyre wear.

All 4 wheels, or just tracking?

4 wheel.

[Andy70]

just curious, this seems common, why would they suddenly need doing?

[helix402]

The car is quite old now, think how bad the UK roads are, add in some wear on the bushes ,; that's why it's wise to have a four wheel alignment. Also everything is adjustable on the E90, camber and toe front and rear, so a good mechanic should get it spot on.

[Andy70]

ok cool, I thought you would need to go to a tyre place and have the 4 wheel alignment service done that they used to charge 100 quid for, can any good garage do it now can they?

[helix402]

Only if they have the right gear (something like a Hunter or Beissbath kit).

[Andy70]

Ok cheers, any idea of the cost of this service these days?

Do have a look at your suspension components.

I had some tyre wear issues on my E91, thread here: http://www.pistonheads.com/gassing/topic.asp?h=0&a...

700 miles of road use!



Basically a full complement of new bushes sorted that out!

[PDP76]

I had all 4 aligned.

[Andy70]

Right, I took the car to pro tyre in Bristol where they have the kit to align four wheels and he hooked the car up and showed me the settings, now 2 of them (sorry cant remember which now)were marginally out by 0.3 of what ever they are measured in and everything else was just within the required parameters, I asked if it would be worth adjusting them and he said no, it should be fine, the tyre wear is due to how he described as an aggressive camber set up from the factory mainly for the fast German roads, he showed me that the back was wearing on the inside and said that's just how they are set up in the factory

[Andy70]

as usual, thanks for all your tips and input guys :-)

Although it's not unusual to see E9x platform wearing their tyres unevenly, it's always down to poor alignment so I can't agree with your tyre guy.

As others have said, these cars are very sensitive to set up, most Kwik fits have a hunter machine and it's worth the money in my opinion.

I've always kept the BMW's properly aligned, and I've had an e90 320D, E91 318D, E90 330D and now an E92 335i, all of which have worn their tyres evenly.

[helix402]

Agree with the last entirely, apart from using Kwik Fit!

E9X does not have front camber adjustment as standard by the way.

Guy was talking out of his arse, they should wear within 1mm across the tyre really.
