Front / rear tire thread depth difference

Just had car serviced, on the service list, it says LF 1.3mm, LR 1.4mm, LR 6.8mm, RR6.7mm, all numbers are average numbers of outside/center/inside
recommend to change front tires.

I wonder why the number differs so much on front tires? it's MB 4Matic all wheel drive, only 35k km driven.

And how to prevent the uneven wear in the future? In terms of driving habit?

the car is on lease, will end in half a year, does have First Class Lease Protection, no additional Wheel & Tire protection.

Will I get dinged at lease end when returning? How much it would cost for a similar pair of tires?

Also there are some scratches on the rim, how much(approx price range) would it cost to have it fixed?

Probably will lease another car from the same dealership.

Im not an expert but I think because tires on the front moves left-right, right-left...and front part of the car is heavier (engine etc) than rear.

Your alignment may be to blame.

tire pressure setting. Some MB vehicles have a higher setting for the front than the back and you may not have set yours properly (for the front)

To minimize tire wear, ensure your tires are properly inflated, ensure that the wheel alignment is correct / checked regularly, and finally, do not drive aggressively.

It's a new car leased from the MB dealership directly, serviced A/B with dealership too, if something wrong, it must be from the day 1st

Perhaps, but why didn't you complain of steering wheel drift or whatever BS you have to do in order to get a free alignment? IIRC MB has 1 year warranty on adjustments etc, so that would have been covered. I've found that many cars do not have alignment completed correctly from the factory. Many MB vehicles also require an additional camber/caster kit or whatnot in order to get all green on the alignment printout results. They cheap out on parts. Ask your service advisor.

btw, are your tires with square setup ? If so, you should have rotated them every 6 months or so (to get even wear)

I've complained about steering wheel drift ( a little bit while idle, but can definitely feel the shake, without Auto Start/Stop function engaged)
I've complained about the sharp squeaking noise when applying brakes half way down

they checked twice saying it is normal...

Most MBs are staggered.

Do you use the same tires in the winter? Also have you ever rotated your tires?

it's all season tires, no winter tires, did not do rotation. Service B lists tire rotation (where applicable), apparently, they did not think it is applicable (did not do)
