Hi folks,

I bought a 6 month old 2023 X7 in May. It had been purchased in October 2022 and winter tires had been put on immediately on delivery. It was traded in at 13000 km (Canada) or about 8000 miles. They put on the brand new factory Continental 22's in May when I bought it.

12000 km's (about 7500 miles) and 5 months later, the rear tires are down to slightly less than 4/32 and dealer says they should be replaced soon. I am blown away. Is this normal? Close to normal?

I have a 2020 X6 M50i on 22's that is still on the original set of rear tires at 46000 km's. I've also owned a 2019 X3 M40i that was notorious for going through tires on the 21" setup and I got 30k+ out of those.

My dealer says it's normal, but I feel like they say that about everything I find ridiculous. Would love some feedback from others.

The X7 is driven mostly on highway and is not driven hard at all.

the contis are not the best...
i measured mine, and after about 3000 miles (the other half on my snows) i'm down to 6/32. another 3000 miles and its going to be down to the min depth for rain.
likely will switch to the DWS06+ when that happens.

Are they known to be better in terms of treadwear?

Not sure why I haven`t heard many on this forum going to Michelin but I'm considering the Michelin Pilot Sport 4 SUV tires - they are runflats, unfortunately (I would rather non-runflat and carry slime). I've never really had good experiences with Continental.

I put Pilot Sport 4S on my X6 M50i and they are rock solid. Still too soon to see about treadwear though.

the DWS06 plus is an ultra high performance all season, treadwear warranty of 50K miles (25K on our staggered sizing) treadwear rating is 560.

the DWS06 is a non runflat.
i chatted with my rep at tire rack. the conti premium contact 6 SSR is a grand touring summer (not high or max perf summer) so the dry performance compared with the DWS06 plus will be comprable. the wet performance of the dws06 plus should be better. light snow, well, that will blow the oem tire out of the water. i run dedicated snows so that doesnt really sell it to me, but the better wet traction and longer treadlife is a big plus.

theres not alot out there in the oem sizes. the only non runflat summer is the pirelli pzero (avail in both runflat and non runflat) but i suspect the treadlife wont be alot better than the oem contis.

Could be the roads you drive. My opinion. Why one vehicle wears treads normal and another faster

[streborx]

The Conti's start out new with only 8/32", so having 2/3's useful life gone at 7500 miles isn't too far off what others have reported -- toasted in 12,000.

Discount Tire's prices on Pirelli and Conti OEM tires range from about $1800 to $2400 per set, which is more than I want to be spending every year. And most of the Pirelli's are currently on backorder. I changed out to a 20" squared-up set of Michelin CC2's. Wheels and tires came to about $2800, 60K treadwear warranty, all-season non runflats. And you can get most 20" tires within a couple days.

[Orient330iNYC]

I'm at 3k miles on the contis and have 6/32nds. Another 3k miles and I'll be down to 4/32nds. Pretty terrible wear. the only summer performance tire i have had that has worn this fast was the bridgestone potenza s03s on my 2001 330i. and i have had summer perf tires on all my cars.
toasted the rears on that in about 7k miles. but to put some perspective on that, it was RWD and i was in my early 20s at the time, so there was a lot of happening....

i suspect its the weight of the X7. im definately driving this car a lot more sedately than any other car i have had that had summer tires. and the roads around NYC have pretty much stayed the same for the 25 years ive been driving here.

[weingarm]

It’s definitely the X7’s weight contributing to the excessive wear on the rear tires.

I have a 2021 X7 40i that came with the square setup 21” OEM Bridgestone Alenzas A/S.

Rear tires were toast at 19,000 miles and I mean TOAST (worn to/thru the wear bars at the inside tread). The wear bars are at 2/32 so they were probably ready to be replaced at 16,000 miles.

Front tires were still maybe 5-6/32 at 19,000 miles but I replaced all 4 at once to keep things even.

On a softer summer OEM tire, I could envision the rears being worn out by 12,000-14,000 miles max.

[Jbird73]

I have a '22 X7M50i with the Conti's that I use 8 months of the year and swap tires for the winter since I am up in the mountains/snow a lot to ski and the summers are not going on those roads.

If I back out the winter mileage, I'm at about 13-14K with the Conti's and they are still pretty darn good. My cheap gauge says 6/32 and no big difference in the rears.

I'm not light in the foot and I would say about 50% of those miles are trips from LA to Vegas. The rest of the miles are a lot of start/stop around town, LA, etc..

It does seem rather random reading the others so I'll just be thankful. Haven't had the brakes checked for measurement but figure I will start getting that done in a month or two at the 20K service check just to know where that is.

I've heard people blowing through brakes and others lasting 50K+.

For comparison's sake, I have 4,300 miles on ours' with 21" A/S OEM runflat tires. My fronts are 7-8 (32nds) and rears are 8+. In all cases measuring the two center areas yielded 0.5-1 (32nds) higher than inside or outside. I'm not sure the starting point.

10/32nds for the Bridgestone alenza sport a/s rft.

if your centers are wearing less than the edges, and the edges are uniform, might need a little more pressure-- the rft sidewalls are likely the culprit, a little more pressure will even it out, but might make the ride harsher.

Did you do a wheel alignment when you put on new tires? 200 dollars is what it cost and I am surprised the dealer didn't tell you that

Thanks. Given 4/32nds is really the ideal minimum, losing 2-3 in 4300 miles isn't that optimistic. We drive the car pretty "chill". I usually get 20-25k out of SUV tires, but admittedly these are my first RFTs. Unsure what the best next tire is, I always go Michelin when I can, but I need RFT and A/S as we annually go to Colorado around the holidays to ski.

The pressure reports as in spec, but I'll check it with my high-end manual gauge and may add some more. We're leaving peak Texas heat, so I'm due to probably top them off as we're expecting our first cold front next week.

[Orient330iNYC]

The spec pressure is geared more to comfort, if you are looking to even out wear a few psi increase on whichever end is wearing the shoulders will help.
You can also rotate the tires to even out the wear, bmw doesn't recommend it as it can cause comfort issues (noise) and let's face it, they don't mind selling you another set of tires sooner
Not a lot of options in any of the sizing with runflats...
The only other all season runflats (assuming you have the alenzas) is https://www.tirerack.com/tires/tires...omCompare1=yes

If you have or can add the spare, the number of options opens up.

Thanks for all the feedback folks.

I wonder if the 2023 X7 is worse because of the mild-hybrid. Are there additional batteries in the back that may be adding more weight on the rear wheels?

its a fairly light lithium ion battery in the engine compartment.
my guess would be under 15lbs

Thanks - that`s definitely not it, then.

My brother-in-law has a 2021 M50i and has the same Continental 22's that I have. His have lasted a lot longer than mine... Was wondering if something changed in 2023.

You mentioned earlier in the thread that you would go DWS06+ when yours are toast. In what sizes?

how much mileage does he have on his?

alignment perhaps?

also, do you carry more passengers or loads than him?

although im seeing similar wear to you, and its usually just me, my wife, and my 5 year old.... so not alot of weight at all.

they just came out in 275/40/22 and 315/35/22. they have them on tire rack, they wont come up as a matched set since the speed rating isnt the same front to back, Y and W. will need to search for them separately.
rep at tire rack said the speed rating difference is a non issue- both tires are rated above the max speed of the X7.

they are not runflats.

Got it! Thank you, they were not coming up earlier on the Continental page, but I believe I either looked wrong or was looking at a different version.

I am realizing that these are the tires that came with my X6 in 22 inch configuration. I have 31k km's (20,000 miles) on mine and just replaced the fronts (went with Michelin Pilot Sport 4S) - unfortunately the load rating is too low for the X7 on those. The rears will be getting done soon too. They certainly lasted a lot longer then the OEM's on my X7. Oddly, on my X6 the rears lasted a lot longer than the fronts. Opposite on my X7.

is the treadwear the same on both (stamped on the sidewall)

it looks like there are variations on the tread compound based on the size based on the traction and temp ratings.
i wonder if they changed the compound in later years. the premium contact 6 ssr is now discontinued. im not sure how bmw was still installing them at the factory since it was supposedly discontinued over a year ago (according to tire rack) the supply hitting the channel now is warehoused stock, once thats gone its done.
