Have 45e (plug-in hybrid) with air suspension and 19 run flat tires, 20k mileage. Decided to do tire rotation and noticed an extensive rear tire wear. Doesn't look normal, isn't it?

Other 45e owners / or x5s with air-suspension, do you have the same wear?

[nZtiZia]

I have 2021 45e also with 20k miles, Bridgestone Alenza RFT 20”. all tires have wear in the inner portion due to OEM negative camber with rears slightly greater than fronts. this is a photo of my right rear passenger tire; note the wear on the left edge of the tire.

Please do not accept opinion that this is normal. It is not and there is an easy fix. Toe to minimum spec. Not in the range, but minimum. Typically, you will need to go to reputable shop and talk to technician to get it. Otherwise, they will set up "within range", what can result in an uneven wear.

Min spec means a negative or positive?
Would you recommend going to the dealership?

Reading on this forum with other generations of X5/X6, it looks like a rather widespread issue.

Same tire and very similar wear.

Haven't looked into G05 alignment specs yet. Does the toe range include negative value? Generally, it should be close to zero, but not zero (rear and front).

Absolutely do not do alignment at dealership.

This is definitely not normal. Negative camber unless severe doesn't look like that. There is some cupping here, the wear on the corner is very well defined. If I have to make a guess, there is either a lot more negative camber, and/or excessive toe, and/or certain change in suspension geometry that cause this. I would say take it to an alignment short and see what they they.

I kind of think this is more severe than OP. OP's wear patch is wider, more gradual. My first guess is negative camber + car running under pressure.

Oh and absolutely with what @bono said. I would suggest don't do it at dealer either, found an alignment specialist.

noted. I drive in Sport suspension level exclusively which is lower than default Normal suspension level

other than an alignment, should i replace my tires or keep them/rotate them?

[eelnoraa]

Just checked my 45e, 11k miles.

Yes, I will take it in for alignment. At current state, alignment shop may want tires to be replaced before doing the alignment. If this is the case, since from the pictures, your tires are still good. Maybe try to remount the tires "in side out", so inner edge become outter edge. This is only possible if tires don't have designated outside/inside directives

Exact same issue here! 2021 45e owner only 25k miles dealer said an alignment is definitely needed and rear two tires also need to be replaced. Will go to a local tire shop to do an alignment and maybe replace all 4 tires.

Did OP replace these two tires? Or all 4 tires?

Just went to Mavis tire shop they won’t be able to rear wheel alignment and actually not sure if alignment can solve the issue. The trend wear seems pretty even to them.

Curious to know what others did, what would be the best option here? Thanks!!!

any specific reason why they won't do rear alignment? and why they said an alignment wouldn't solve the issue?

They said they can do front alignment which is more common and no proper training and equipment to do the rear ones. Not quite sure why this is not an alignment issue of the rear wheels.

[eelnoraa]

How about visit a suspension shop? These usually are more knowledgeable about alignment than a tire shop. No reason why the rear cannot be adjusted. It’s after all double wishbone with trailing arm, should be very adjustable.

I think rear measurement and adjustment make sense and match your tire wear. Most street cars, except those specifically tune for handling, should have positive toe (toe in) for stability consideration on both axial. Negative toe (out) + negative camber will cost excessive wear in the inner edge of tires.

For the front, I think even the before measurement looks ok. Just slightly less positive toe then oem spec. As long as it is still positive, and total toe is positive, it should be ok.

Feels the same, no issues.

Same issue here. Our '22 X545e with 21k miles did not pass state inspection due to rear tire wear on the inner portion of the tire.

I'm looking to probably replace with All-Seasons. Continental DWS 06 seems to be a popular choice? We live in NW PA, snow but not as much with warming climate.
