Have a 2012 X5 with 20 inch alloys and non sports suspension, the outside of both front tyres is starting to show signs of very noticeable wear , what would cause this and what should the correct inflation be ?
Cheers

Front tyres outside wear
Re: Front tyres outside wear
Tracking errors are a frequent cause, assuming your Suspension bushes are all OK.
The default settings from the factory are not as good as they could be and owners often find that getting a 4-wheel alignment done improves this particular problem. Potholes can also throw the alignment out too.....and UK roads are not exactly well maintained >:(

Never anthropomorphise computers. They hate that.Re: Front tyres outside wear
Of course you could also be having too much fun going around roundabouts...... O:-) O:-) O:-)
Re: Front tyres outside wear
Its usually caused by too much toe in .
Also check the VERY inside edges of the rear tyres. They are prone to wear, caused by too much -ve camber... Its a typical X5 fault.....
Oh and DONT take it to you BMW main dealer, they will most likely say its within tolerances.
BMW tolerances are too wide.
Take the car to a garage that has a "Hunter" machine. And ask them to set the car to your own specs. I set mine to ,, rears -1deg camber
Front toe in total 0.10,, i think.
But if you search on here youl soon find some of my posts about this very subject...

Re: Front tyres outside wear
As above.
If it was underinflation then your front tyres would be likely to wear more at both the outside and the inside.
I had your problem on my first set of tyres on my E70. When I replaced all 4 the issue was solved - likely by being fitted correctly!

It'll be allright in the end. If it isn't allright it isn't the end

Re: Front tyres outside wear
Hello,
As above - I had exactly that problem - fronts wearing on the outside and rears on the inside. A tyre specialist with the right measuring machine (I think mine was done on a CORGHI) set the front and rear toe in to the minimum limits and also checked front to rear alignment which is important to stop the car crabbing down the road!
Since then wear has been even over 3 sets of tyres.
One other thing my usual trip to work involved three right turns at unrestricted roundabouts twice daily but I retired 3 years ago and that's saved wear on the nearside front (UK)!!!

Re: Front tyres outside wear
thanks All, i've pumped up the front to 34psi and will see how that goes.
Re: Front tyres outside wear
Hi Diluxe,
That seems high unless you are carrying a load. What does the plate on the B post of the driver's door give for your car. Mine says 2.1 bar (30.5psi) for a normal load (5 passengers and luggage). Over inflation makes the ride jarring and can cause too much wear on the central part of the tread. Can I suggest much better to get the tracking checked and set by a specialist and use the recommended pressures!
