Continental DWS 06 Plus 245/50/19 installed and performance results

@lurker @kkgg Here are images of the Continental ExtremeContact DWS06Plus in 245/50ZR19 on the stock MME 7” rim. Hope this helps.

Yep, I think the fitment is fine

Is this on the stock premium 7inch wheels? Can you add front and side profile pics? I was afraid if I added these to my wife's car, it would have that bulgy sidewall look to them

Also, any reduction in the bounciness with wider tires (sorry, I am a noob at this stuff)

I think the ride is better than the stock tires

New tires have a bit of squirm and extra rolling resistance before the tread gets broken in. Old tires get more efficient as the tread wears down so the efficiency comparison of old vs. new isn’t straightforward.

Alex on Autos swapped out his 4X stock tires for 245s very early in his ownership experience and the range was nearly identical.

This is true. But it is also true that some tires have higher rolling resistance than others, and you can definitely see the impact when comparing low rolling resistance tires with tires not designed for low rolling resistance. 10% does seem high, but definitely possible. I would expect 5% hit, so maybe it will settle to that as the tires break in.

Rolling resistance effects range at all speeds. Aerodynamics effects range as speed increases. While this is obvious, I just want to point out that you could have poor aerodynamic rims and not notice a range impact if you mostly drive slower than 35 mph. But if you do a lot of highway driving, you will notice an impact with rims not designed for good aerodynamics. New rims and tires together could easily make a permanent 10% range hit.

I put the same tires on my car at about 300 miles as the stock tires were terrible in any rain or snow and would spin like crazy. Great difference in cornering as well as wet weather traction - even dry weather/launching without spin for that matter. My range is ~280 miles with these tires on my 2021 GT.

I am surprised you had that experience on your stock tires. I have loved the performance on ours. Great in the rain, snow, dry, you name it! I was prepared to replace them right away if they were poor in the snow, but they were great. Very confidence inspiring. Sounds like a very different result on the same tire...

Don't the GT's come with a different tire? The Premiums come with Michelin Primacy AS.

So, my 225's finally needed to be replaced so I decided I would go to the 245 50 19's and here are some of my initial observations. The ride is way better, smoother, quieter and better traction. The range question always gets asked so after my normal commute what I saw was a 10% decrease in range. Normally it takes me 16% battery to drive my 46 miles and this morning it was 18%. I have been getting 3.3 mi/kw under same conditions and this morning it was 3.0 mi/kw. It will be interesting to see the impact in the winter. As of now, I'm good with losing that amount of range but may consider lighter rims in the future to see if I can get a few percent back.

The DWS06 Plus is a great tire. I've been using them on my 16 Chevy SS since I took the summers off year 1. I get about 35K from them and they do everything well.

Thank you so much. This looks great!

I'm looking for different wheels for winter. Does anyone have a wheel size I can use on the GT-PE to get over the rotors/brakes? I've read 19" is the smallest I can go.

I genuinely wish we had tire rating like Europe this would not be the mystery it is here. With some detective work we can see that the factory tires would be euro-rated "A" the DWS is a north American-only tire but my guess is it would be rated "E" which would be 10% or what you have described for range impact. Tires like the premium contact 6 are either rated "A" or "B" depending on their size tires like the Michelin CrossClimate are euro rated "B" and would have a minimal impact on range. Euro ratings a 2% efficient difference between letter grades.

I had a similar tire to the DWS in a 245/50/19 and custom wheels together they had a considerable impact on range. In town it would do OK but on the highway 2.3m/kwh.

I agree with the need for a more detailed tire rating system like in Europe. When looking at European tire ratings, keep in mind that tire mfgs often use different tread compounds for the "same" model tire between North American and European markets.

Despite the good rolling resistance rating in Europe, the North American CrossClimate 2's reportedly affect range significantly unless you overinflate them. My parents have CC2s on their Rav4, and the rubber in them is SOFT in the summer. I was shocked how pliable the treads were with just my fingers. They sure don't seem like they'd be low rolling resistance, although this is hardly a scientific observation.

What tire did you have which was similar to the DWS06+?

I think Tire Rack reviews confirm your assessment of Cross Climate 2 rolling resistance. Tesla drivers complain about the range impact.

Vredestein Hypertrac it in many respects outperms the DWS, definitely not as well known. If I would have installed on the factory wheels my efficiency results would have mirrored yours with the DWS.

I switched to the Quatrac and CR1 wheels the tire is not as sporty but the difference in range is significant. Also they are considerably more road feel and handling ability than the factory tires

I am not advocating for the cross climate my only point was it should be more efficient than the DWS. I would personally not install a directional tire on the MME as my summer tire. Why? Because you can't rotate probably and that is important on a heavy EV like the MME

Couple things about Rolling resistance a very soft tire has low rolling resistance and short tread life. Rolling resistance is about using less kinetic energy to deform and then reform the contract patch so a soft tire will do that very well. Also for people like me that live in the snow belt an all weather tire like the Quatrac or cross climate will be much more efficient on a cold day because the rubber is more pliable. Same bennifit can be had running winter tires in the cold.

It's true some manufacturers do make a different tire for the us and Europe some don't that's easy to figure out. If the tire uses the same bar code/ product code then it's the same.

I agree with Bill. Changing your rims is very unlikely to improve range unless you go with something like what is on the CA Rt1 MME. Aerodynamics play a much bigger role than wheel weight.

Wheel aerodynamics play a marginal factor, just as the weight of the wheels. Sure you can get super light forged aero wheels, but that is all negated unless you go with an eco focused tire, that isn't super wide. Range loss is 90% attributed to tires that have a wider contact patch against the pavement. More contact = more friction = lower efficiency. The best way to offset this is to go with a tire option bringing some sort of eco focus rating, which typically includes a lower rolling resistance.

The data I have seen demonstrates wheel aerodynamics has a significant impact at highway speeds. I agree it has a minimal impact at city speeds, and rolling resistance impact range at all speeds, but I don't agree wheel impact is marginal. I guess it is marginal if you live in Hawaii and never go over 45 mph. But not on long road trips at 75 or 80 mph. Definitely not marginal at those speeds.
