2012 X5: one year tire wear data, tire rotation

[JimS X5d]

I have a 2012 X5 35D and attached is the sticker in my door jam.

good alignment should solve this, there was a thread in this forum recommending some alignment numbers

Thanks posting this, Jim.

These number makes a lot sense, which is close to what I have set now.

If you drive YOUR X5 in the fully laden condition (4 pax plus luggage) then you should follow the door jam.

I tend to go more balanced with pressure front and rear, and bump it up if we will be hauling a full house (rare). I also use more up front than they recommend, preferring to limit wear on the outer edge by running 34-36.

1- Front tires are wearing badly in the outer edge

I was thinking to follow the PSI of the 20inch tires, as 32F and 35 R
any thoughts ?

I'm experiencing the same thing with both my summer (Bridgestone RFTs 20 inch staggered) tires and winter (Pirelli Scorpion 20 inch staggered). Front tires were wearing badly on the outer edge, so I took the pressures up to the >100 mph spec (42 front, 45 rear). That seemed to help with the wear issue with the fronts, but it seems to have also caused the rears to wear in the centers. So I'm leaving the fronts at 42, and taking the rears back down to the original 36. Hopefully that will not cause a handling issue. Comments/suggestions? Thanks in advance for your help.

You are likely to experience a handling issue, as you are changing alignment settings by altering the stance of the vehicle. I would not recommend that you run front tires at a higher pressure than rear tires on this vehicle.

Wear on the outer edge of the front tires may be related to your cornering speeds with such a heavy vehicle.

There are multiple variables that impact tire wear. ALIGNMENT is a major factor and is almost always unknown. People can adjust their tire pressure so they try that..but unless you know the alignment is optimum and THEN adjust pressures fore and aft, you are kinda guessing.

I do agree with the higher up front, as stated earlier- especially if you are driving around most of the time not fully laden

Thanks for the responses. I actually went ahead and lowered the rear pressures before I read your responses, and I pushed the truck pretty hard on several entrance/exit ramps on my way to the office this morning. Can't say I noticed any change in the handling. On this truck would you expect that what i did with the pressures would cause an understeer or an oversteer?

I have 30k miles on the truck, and it's never been aligned. Have never hit any big potholes (amazing, given that I'm in New Jersey) nor curbs, etc., and I assume I'm not seeing any tire wear indicative of an alignment issue (I was thinking the same thing that the wear on the fronts was due to cornering speeds, and that I could offset that by increasing the front pressures), and the truck tracks as straight as an arrow (I know that's not proof at all that the alignment is not out of spec).

truck..truck...truck???

Hmmm...

Oh, you mean the X5?!?!?? Its not a truck.

You will not notice any handling issues IMO, your still above what the tire needs to work and the wheels are so wide the tire will be happy with just air in them

To fix your outer edge wear slow down.

This is all assuming you have the correct width wheels, some of the aftermarket stuff is narrower than OEM.
