Early & uneven tire wear (i4 M50)
Hi,
I have a '23 i4 M50 with around 7k miles. Have had it for over a year mostly for local commute. I happened to be at the local dealer for another issue and they told me there is heavy tire wear on the rear tires, they are almost gone. Would be 750$ to replace just the rear tires. My question is the following: why is there uneven wear on the i4 M50? The battery weight is distributed across the front and back right? and it is a dual-motor i.e., 4 wheel drive? Shouldn't the wear be even between front and back? Also have others had to change their tires after 7K miles? Seems too early even for a heavy electric car. Hankook is the brand of tires I got, if that matters. -Ram |

When I connected Bimmerflow to my M50, one thing that was noticeable is that power only went to the front wheels when you were accelerating fairly hard. General cruising seemed to be rear-wheel drive.

Is dealer suggesting an alignment issue? While the car is heavy I would think 15,000 miles would be a reasonable expectation, even if your right foot is a bit aggressive (from time to time)

Granted, my M50 is on order, but I've been on the this and the i4 talk forum for a little while now.
From what I understand (and from my own experience with hankook tires on other cars), out of all the OEM tire options on the M50, they wear out the fastest, by far. The sport hankooks I've had on other cars are great, but they have worn fast for me... however the quick wear borders on ridiculous for the M50. There is likely more tire wear in the rear because even though the car has power to all wheels, the delivery is very rear biased. A lot of the time the car is full RWD unless the front is needed for launching, cornering, etc. Maybe try swapping out the tires completely for a full set of another brand of OEM BMW star tires. The pirellis and michelins will likely wear much better.

Yeah we have major tire wear in the inside of the rear tires on our M50. I didn’t notice until the rears were corded on the inside. Got about 13K miles before the rears had to be replaced. The fronts are still going strong at 18K. I estimate I’ll have to replace the rears twice for every change of the fronts.

Had the Hankooks from factory on my M50 and had to replace them due to the rears being worn at 6k.

Please specify what kind of wear you have. Talking about having uneven wear but not stating what is uneven is leaving out information of tire measurements. It is very common for any BMW to have heavy rear tire wear before the front. Completely normal for an i4 M50 especially if you like to accelerate a lot. Tires don’t last 30k miles anymore especially for any of these BEVs.

All too common with BMW EVs now. Completely normal. Customers don’t realize tires will be replaced much more with EVs.

I got 8,000 miles on the original Pirelli Pzero summer tires. Switched to the Goodyear Eagle Sport All Season Tires. OEM German made tires with a 500 tread wear rating. Good in damp conditions and good enough in the dry. I think I will be on track to get 12000 miles on them, which is about 50% more than I got on the Pzeros.

I have my original front tires with 16K miles ( 20") and replacement rears at about 12K. The fronts are almost gone but the rears have life.
When I lowered my car I had them take the toe-in out because that causes scrubbing and excessive tire wear. You won't notice the handling difference.

Crazy rear tire wear
i4 m40 rear wheel drive, OEM 19" Goodyear Eagle Sport. first rear tire failed around 18,000. massive inside edge wear down to the metal cords then a blow out and instantly flat. first thought is out of alignment, took it in, not bad, perfect new alignment, then 2k miles later the other rear tire blows in the same manner, stranded both time. NOT an alignment issue .
BMW dealer said I should be more careful and monitor the tire wear better. BMW North America said nothing they can do, dealer issue. i4 m40 is 25% heavier than similar 4 series and yet they use the same tires. 900 lbs added weight, added torque, the added heat from the weight and torque. this wear is super hard spot and seems to accelerate very quickly at the end. see pics from both tires. not happy with BMW. I had this issue with all three of my i3s, but at least it was even wear and could be seen. I asked my dealer prior to ordering about rear tire wear, was told it was normal, nothing special and used standard tires, not special EV tires. to me this is a BMW issue, either bad OEM tire choice, bad batch of tires from Goodyear or bad design (camber/toe in) set up. |
