I went from 17 summers to 16 winters. I lose efficiency. I know supposedly larger rims make if worse but the difference in summer vs winter even in same temps is huge. I haven't tried swapping just tires as I swap rims as well. I assume the winter tires are just that much worse.

I talk about my diesel smart a lot, I know, but it serves as a good benchmark for a lot of purposes. When I was running it on the stock Conti EcoContact summer tires, I often averaged 3.7 l/100 km (more than 63 miles per US gallon) over the course of the summer; switching to Conti WinterContacts in the same staggered sizes (on steelies though) cost around 0.8 l/100 km (11 mpg). Later I went +1 with larger, stickier UHP summer Yoko s.drives (uniform sized front and back, but staggered offsets) and summer FE only took a small (~0.3 lhk) hit, but switching to a +1 Nokian Hakka R3 setup for winter (uniform tires and steels all around, spacers in the rear) resulted in zero efficiency loss. They may be more expensive to buy, but Nokians are hard to beat in performance, efficiency, and longevity, so they end up cheaper than lesser tires.
 
Not too much of a hit with my nokian wr-g4s.
I gave my car a charge this morning in 59F temps and wasn't far off summer mileage. Battery temperature makes a huge difference. Unfortunately, I have a carport, so battery heating is only achieved by charging.
I found only one economy A rated all season in a UK tyre site
Goodyear vector 4 seasons. The euro tyre labels are a great way to asses actual tyre performance.

The couple of sets of Blizzak (full winter) tires I’ve run in the past did stick like glue on ice and hard-pack, but were the loudest, squirmiest, least fuel-efficient tires I’ve ever owned. Luckily, they also wore out very quickly and were replaced with less frustrating tires.

We had them years ago on our 2010 Clubman and I don't remember hating them, but I have a set now on my SE and they are the worst on anything that isn't ice or snow. I don't trust them at all at this point and can't wait to put my summer tires on this weekend.

I originally was going to buy Sotozeros since that's what we have on our current Clubman (and they do well, though AWD certainly helps), but tire inventory was crazy last winter and I bought whatever I could find at the time. Oh well, live and learn.

Basically exactly this. We average around 7 feet of snow per winter, but we have the largest snow removal budget of any city on earth, and despite how locals love to complain about the city crews, our roads are basically bare all winter. So on bare pavement, they just squirm too much, and the moment it goes above freezing, they wear like a pink pencil eraser.

Broken record: AWD doesn't help you stop or turn, arguably the most important functions of a car!

Not directed at you particularly but I'm going to keep repeating myself until I stop hearing people use AWD as an excuse for having inadequate tires.

All winter I hear about people complaining about how bad the roads are and how they almost slid off the road then saying something along the lines of "good thing I have AWD, I can't imagine how bad it was in your FWD".

Has anyone went to all seasons from their summer tires and not lose any efficiency? I’m on 16’s and have a set of all seasons (blizzaks that came on loop spoke wheels) and I tested them the past couple weeks. I get about 3.5 mi/kWh on the all seasons and currently getting 5.0 on the summer tires. I’m hoping there’s an all season that doesn’t lost a lot of efficiency.

also has anyone upgraded to 17” wheels from 16’s? Wondering if there’s a huge difference.

I'll never understand how people get 5kw.

I was helping someone move in December, 2001, and we had to run from his new, downtown condo up to the old house in tony upper Westmount, and I remember being utterly impressed by his powerful Infiniti Q45 not losing its composure heading straight uphill on the steep, snow-covered street. The guy simply pointed out, “Traction control.” Enough said. I was sold on the the future right then and there.

Summer tires + urban driving. There are also some efficiency gains with the 17" power spoke wheels but less important in the 2022+ models with the air curtain bumper redesign.

Passing 4000 miles on mine now, I’m quite certain I’ll easily hit 145 (calculated) miles this spring, and then some. I’ve done 120 (calculated) miles a few times already this winter, at temperatures around freezing while on 16” winter tires at 38/35 psi.

Agreed on the stopping, but not on the turning. Having the car shift more power to the rear when you start sliding is helpful (and fun!).

But on a very sharp turn or sudden serve, agreed it's not going to do anything.
 
I'm getting over 5 mi/kWh during the summer with mostly highway driving, 85 miles a day. I think the trick is I use cruise control as much as possible.
 
Usually see well over 5.0 mi/kWh on 16 OE Ventus Prime 3 with warmer temp. Usually includes some spirited sprints and always in Sport.

Though the best I've seen on the wet weather AS tires (Vredestein Hitracs) top out at 4.5, but usually see 3.7 to 4.0 to include wet roads with temperatures above 35F. Still rocking the 16 inch wheel, but 205 width over the 195 OE size.

Our average in the warmer months with the stock summer tires is about 4.1. My wife is the primary driver and commutes about 25 miles to work, mostly on the freeway. She also uses low regen and refuses to change her driving habits at all, so does nothing to optimize the EV.

I have a "winter" set of Continental tires that are supposedly quite efficient on a set of stock MINI wheels (I forget which ones, but I think they were an option on the SEs as well). During the 5 months these are on the car, we go down to about 3.2. But I cannot really tell how much of that is the tires and how much is the cooler weather (lots of uppers 30s and 40s with occasionally lower or slightly higher temps). As an example, last week the news made a big deal about hitting 60 on Friday for the frist time since October! The winter set has been on this year since early November and will probably come off in a couple of weeks.

Here's my thread about my new wheels and tires: https://www.insideevsforum.com/comm...er-wheels-and-tires-and-resetting-tpms.12617/

I struggle when I read that people get over 100 miles of range even when driving on the highway. Maybe it’s my speed (70-75mph) or my tires (Continental Extreme Contact DWS 06 Plus) but something is up.

I’ve gotten 110ish doing back roads but I often wonder if there is something wrong with my car as I read others get that on the highway and 125-150 miles in non-highway driving.

Do the tires have that much of an impact on range? I always drive in Green mode with high regen braking.

Thx - MikeG
