CONTINENTAL EXTREMECONTACT 06 PLUS INITIAL IMPRESSIONS ON 2022 X3 M40i

I thought I’d share a few first impressions of the Continental Extreme Contact 06 Plus All Season Non Run Flat tires that I recently had BMW install on my 2022 X3 M40i 699M 20 inch wheels- 2 weeks ago.

There aren’t too many reviews of the new DWS 06 Plus Tires on a 2022 X3 M40i running 20” 699M wheels (yet) so this review is for all those with this configuration. Most online reviews of this tire come from people driving 2021 M40i’s but in my opinion the 2022 M40i has a softer suspension setup than last years model.

* I’ve put 1,200 miles on these tires and driven on them in all conditions except snow. They’re inflated to 32/35.

COMFORT: ALENZA WINS
I was completely expecting a noticeably softer ride given the Alenza is a Summer RF Tire. Nope. The Alenza’s, at least on my 22’ M40i, provides a “slightly” softer ride. It’s not a huge margin but I honestly can’t give the nod to the Conti’s here. I saw an online review of a Continental engineer talking about this new DWS 06 Plus tire and he said they prioritized handling and sharpness. That might be so but I’d bet that came at a cost. These tires feel almost as hard as my Pirelli P7’s run flats on my 2019 X3 30i. To me they feel like they’re over inflated by 7-10lbs-they’re not…checked them with a digital tire gauge. Overall, I am a bit underwhelmed versus the Alenza’s. Surprise

HANDLING: ALENZA WINS
I think this is a closer call but when taking long sweeping on ramps at a good clip M40i

RAIN / WATER: ALENZA WINS
Shocker! It’s been cold and rainy here in MN the past few weeks and I’ve had a chance to do multiple 200 mile road trips on these DWS tires in the rain. The DWS 06 Plus tires hydroplaned once already on me and the road wasn’t that bad. Based on this I can’t give the DWS the win because the Alenza’s never once lost traction on wet roads. 1-O Alenza (go figure). I have read that new tires can be slippery so potentially I need more break in.

SNOW / ICE: TBD
I expect the DWS tires to crush the Alenza’s on slippery wintery roads but this is not a fair comparison either. I’ll know soon enough!

DURABILITY: 10/32 of starting tread
I hope to get 30k miles out of these DWS tires on my staggered setup- TBD

That it for now until the snow flies

Really interesting and valuable post! I have the exact same wheel/tire configuration on my LCI M40i and have been looking at the Conti DWS06 as well as the Michelin Pilot Sport A/S 4s but now I'm wondering if I should just stick with the Alenzas...

Thanks CJ! Should be interesting to hear from others who go the DWS 06 Plus direction on the 2022 X3/4 M40i.

Thanks for sharing. I just did this swap today. I've only done one drive but the DWS seem to be much more cushy. I didn't mind the Alenzas but winter is coming...

I've had mine since late last week and will also disagree with Jen and say that the Conti's are definitely a softer, more comfortable tire than the Alenza's that came from the factory.

They are definitely quieter as well.

It's been less than a week so have not had a chance to push the handling aspect as I'm waiting for treads to break-in a bit before pushing them.

Very interesting. I'm actually in the minority that I like the RFT Alenzas. The only con I think is that they are noisy (I'm not sure if it is only the tires but they probably contribute). I'm also someone who prefers stiff to squishy, which most people don't. In my old 328i, I changed the RFTs to Michelin All seasons and it was softer no doubt, but seemed wobbly in corners. So still considering a change to non RFTs when the time comes but not totally sure.

Also recently some fine folks tried to carjack a friend's Model Y using nails - he drove away with a flat tire basically on rims and ended up with quite a bit of damage/repair. The RFT would be super handy in a situation like that.

I like my Alenzas too, which surprised me. I haven't noticed any noise, but I have quite elderly ears. Strangely though I can hear all the other out-of-the-ordinary car noises that occur when something is not right.

Interesting... I'm just a few weeks in at this point, but the DWS06+ on my 2019 M40i are significantly less jittery and harsh, tho did I lose some of the crisp urgent turn-in of the Alenzas. The real kicker tho is the Alenzas amplified and jumped off of every minor road imperfection - of which we have a lot - to the extent that the ride was constantly nervous and just totally obnoxious. Very happy to have them gone.

Intentionally chose the Conti over Michelin AS as the AS3+ I had on my 330 were also pretty harsh around here and reviews for the AS4 suggest they're just as stiff (they handled insanely well tho). X3 needed something softer.

I'm curious as to what's changed in the '21/22's from a spring rates, damping rates, sways, and geometry perspective tho. BMW got it pretty wrong on the earlier versions, imo (unless you live near velvety-smooth roads)... I'd wager there's significantly more small-bump compliance built in now. Bigger body motion has never been a problem, it's the little fidgety stuff that sucks.

Interesting. I felt that the DWSs made the ride less harsh. Although, I did make the switch when it was still 70 degrees for the high. So, maybe that had something to do with it. Didn't drive in any heavy rain in the Alenzas, but I did take a 300-mile road trip with the DWSs in the pouring rain. I was driving 70-80 the whole way and never once hydroplaned.

prototyp, the tramlining of the Alenza's annoy me since the roads here in Utah are horrible for it. So definitely curious to hear if the Conti's, or other AS non RF, are less susceptible to it. I'd be more than willing to give up a tenth in handling to not have tramlining.

Haven't tramlined in the DWSs ever. I've got about 1,200 miles on them now. Never tramlined in the Alenzas either, though

I really enjoyed having my NON-RFT alenzas (now on snow tires). I mean, all season tires are trying to be a jack of all trades, so it makes sense that summer tires handle better. Summer tires with their large grooves are much better at preventing hydroplaning than all seasons with mixed grooves and sipes.

I have just purchased a 22 X3 M40i. I have a 16 Porsche Macan S that I run Sumitome tires on. They are high performance AS.

If I replace the RF, I will put these tires back on. Macan came with Pirelli Scorpions. I did not notice any decrease in performance with these Sumotomo tires.

I love this topic. My 2022 X3 M40i is in quality check, so it should be here “soon”. Here is Michigan and I had to order with the 699m high perf tires, so I’m debating swapping tires or getting a full fledged wheel / tire set. Reading this thread makes me lean toward saving money and just getting tires.

Noticed much less tramlining, tho conditions are likely different from near you... Surely the tire's sidewall stiffness is a big contributor, as is tread pattern, tho some of it is down to alignment & steering geometry. We've got some lanes with more-or-less longitudinal troughs, cracks, and differences in pavement height thanks to expansive clay under the roadbed and many sycamore trees. The Alenzas wandered all over them, Conti's not so much. There are some grooved concrete freeway sections in the region that are a bit of a handful, but I've not been over them since swapping to the Continentals.

It's the track-day sharpness of the Alenzas that makes them so responsive which also makes them ... too responsive. Haven't been out hammering some winding roads yet to assess subjectively how much responsiveness got lost going to the softer DWS, but the gain in daily real-world drivability is significant enough that it's not even a debate. (There's also presumably more range for tire pressures to play with on non-RFT; higher for more crispness, lower for comfort)

Thanks for the review. Can't wait to see your review of snow handling.

Why? The reviews on Tire Rack were so impressive; however, on my Audi A4 Quattro, I was extremely disappointed with the DWS (not the +) and how it handled the snow in Colorado; additionally, my impression of the overall ride was that the tire felt ... for lack of a better word, squishy.

And, thus, I replaced the Alenza and put the Pilot AS4 on my '22 X4 M40i.

Super curious of your experience and hope you will report back when the snow starts flying in MN.

Awe crap Jen, I just order these with BBS black rims from Tire Rack. I was going to order pilot sport all seasons, but they are back ordered further out than the Conti’s. I actually love how the Alenza’s ride and handle. I was forced to drive in 30 degree weather yesterday and zero issues.

I just swapped out my alenza run flats for the michelin pilot 4 AS and i def think they are a bit more comfy then the alenza's but thats my opinion. for anyone who live in the NYC area and loves the alenza's a have a set w/ only 120 miles them for sale!!

In all probability the DWS tires probably are technically softer tires. No argument here. They just seem bouncier and a bit more jittery on rough roads versus the Alenza�s but there�s not a vast difference. I can see how you could disagree with my review. The differences are not night and day.

Agreed, this is the proverbial "butt dyno" at work! The feeling is really subjective. This is also a function of the suspension setting we choose so folks will have different experiences/perceptions.

Roads here in NOLA are awful, built on old swamp land. The firmness of the RF Alenza was just too harsh for me.

M40i guy- I love those black wheels you picked out! Seriously these Conti’s are not bad tires. I’d say they Conti’s are more responsive than the Alenza’s and for all I know brake better and can pull more G’s. They track great on the highway and they’re quit. They’ll definitely out last the Alenza’s by a mile. You might love the Conti’s I just think the casual city driving comfort factor seems a bit more nervous than the Alenza. There no way I’d called these Conti’s soft though on this 2022 M40i. I had a 2021 loaner X7 when I did my tire swap to these Conti’s which wore Conti contacts and that ride was cushy soft to a fault.
