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.

Not sure about the DWS, but I have been very impressed with the Continental cross contact tires that come stock on the GT. Great grip and performance in the warmer months and above average performance in the snow. Plan to get them again when it is time for a replacement.

I too am running the Cont. ExtremeContact DWS06Plus in the 245/50RZ19 on the stock Premium rim. I agree with your range drop numbers. Frankly, I really like the look .... aggressive.

I would be cautious about a rim change as these rimes were designed for best performance though the slight bulge created by the 245s may change that.

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.

Curious how many miles you had on the stock tires?

I was looking into doing something similar, but 10% is high price to pay.
I got the summer tires, so hoping it will perform well enough.

The OEM Continental PremiumContact 6 summer tire option has noticeably more grip than the OEM A/S Michelin tires, as expected. However, even though the tread pattern is more aggressive it’s still too narrow looking.

I had 26K with 4/32 tread left
New tires will always give you a range reduction vs worn tires. I think losing 10% isn't bad given what you were comparing it to.

If you don't mind giving us an update in ~4-6 months I'd be interested to see if any of the range came back.

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)

+1

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.

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