I just put these tires on my 2015 this weekend (and pulled off the Yokohamas on the front with 10K miles on them) - the ride is much better! I only lost 3 miles of range for my commute for 1/2 tank. America's Tire Black Friday sale gave me another 10% back too.I'm VERY happy with my 205/50 15 Hankook Ventus V2 Concept 2 set that I've had over 5k mi. Better than the stock tires in every way*, including cost, grip, wear, & appearance.
*Except: Range per charge, which is equal even though weight is 1 Lb more.
What yokos did you have?I just put these tires on my 2015 this weekend (and pulled off the Yokohamas on the front with 10K miles on them) - the ride is much better! I only lost 3 miles of range for my commute for 1/2 tank. America's Tire Black Friday sale gave me another 10% back too.
You're the best person to make that judgement, based on your past experience with winters at your location. If you've used all season tires in the past, think about whether you were in situations where you wished you had snow tires.debating just buying a set of winter tires but would prefer to not have to store/change tires again in the spring.
For ME there was NO difference in range when I switched from the STOCK tires to those Hankooks. I drive mostly city, & averaged almost exactly 1 mile per % on stock tires AND on new tires, and:I just put these tires on my 2015 this weekend (and pulled off the Yokohamas on the front with 10K miles on them) - the ride is much better!

It might even be safe to say no tires exist that aren't WAY better than stock.I think it's safe to say any good set of tires is worth getting.
*ADDENDUM:My range predictor fluctuates wildly and it's not very good- 60-70 miles, but I drive up a big hill every morning
- the bigger size is nice: the front scrapes a lot less
How are you arriving at 2 mi per 100 and 2 lbs?Thanks for the report. I'm curious how you tested the range.
Due to their full-depth tread, those brand new Kumhos are actually going about 2 miles further (per 100 odometer miles) than OEM tires that are worn to barely-legal tread depth. If that wasn't accounted for, then it's only about 3 miles of range loss, which can happen with a very slight headwind.
The unworn weight specs are identical, so the new tires are each nearly 2 pounds heavier than worn-out OEMs. By suddenly returning to the original OEM weight, you just added about 8 pounds to the mass which needs to be accelerated rotationally as well as longitudinally. That can hurt range a bit when you're not at a constant speed.
In other words, based on your note I would bet that the range of NEW OEMs & those new Kumhos is virtually identical. I get identical range as OEMs with 205/50 Hankook Ventus V2 Concept 2.
Better grip doesn't necessarily mean more rolling resistance. Anyway, higher airspeed, such as a slight headwind or not slowing for corners, is by FAR the biggest range-reducer, so now based on all of the above, a fair range comparison would almost certainly be identical.I kept a mental log for the first few months of commuting. Not the most scientific approach, but it could have a little to do with the higher rolling resistance of the tires AND my right foot enjoying the new found cornering grip.
Some weeks the range was identical to the OEM's. So it's very possible they are nearly identical.
Gotcha, and you could use that geometry if tyres were rigid bodies. In practice you need to think of rolling radius and while tread can have some impact on it, once you consider tread squirm, construction/associated deformation, centripetal forces, load, pressures, etc. you’ll see that it’s minimal.OEM diameter spec is 23", times Pi = circumference of 72.26"
OEM diameter with original 11/32 tread worn to 2/32 is 22.44", times Pi = 70.49"
That's 98% (2 miles less, per 100 miles)
"2Lb" I got by weighing a worn-out stock tire, so that number is only as accurate as the tire specs. Regardless of the actual number, a tire definitely loses rotational mass as it wears.
