Hard to do with the house arrest anklet on.
Let’s talk about tires.
it seems
To
Me to achieve any sort of reasonable range, EV’s are equipped with tires that are only suitable for places where weather does not occur.
Im places where it’s likely to snow on any given day 6 months of the year, such tires are worthless. Particularly on a truck.
Does anyone know what kind of tires are expected on the F150-L?
im pretty sure the Tesla truck will
Not have tires that actwork in the winter.

i don't Know.
where You're getting you're Information
From.
there Are no special tires for
EVs.
You Can put any Tires on an EV
that
you want
Why evs use special tires
The tires on evs are engineered for lower rolling resistance, to increase range. That means they are more narrow, and have a reduced tread depth. swapping out these for aftermarket tires can reduce the range (an example of how the range numbers are gamed by manufacturers).
My Tesla Model 3 uses pretty standard Michelin Sport tires.
I thought they used ones with thinner treads that have some other EV specific features?
Article doesn't give any data. Not doubting the conclusions, but what are the real world numbers?
Tire diameter certainly has an effect on range, but that's true of any vehicle, ICE or EV.
And regarding winter driving, plenty of people in New England, Canada, and Scandinavia are driving EVs. Consensus is that EVs handle just as good, if not better than ICE vehicles on snow/ice.

But range isn’t an issue with ICE vehicles, so it’s only an issue with EVs. And sport or high performance tires are equally limited in winter conditions.
I don’t doubt that plenty of people in New England drive EVs, but where in New England? Not northern New England. Most likely Boston and burbs. Not quite the same.
New, scalable battery chemistry possibly on the horizon:
https://insideevs.com/news/575609/tesla-elon-musk-potential-manganese-based-battery/
In order to transition the world to sustainable energy, it is estimated that 300 TWh (terawatt-hour) of batteries are needed. That's a number difficult to get your head around. While the short term concern regarding EVs is semiconductor chips, the long term limiting factor will always be batteries, batteries, batteries. This might help grasp the volume:
1 TWh = 1 billion kWh
A long range Model S has a 100 kWh battery pack.
Therefore, the 300 TWh of batteries needed for global sustainable energy, would be equivalent to 3 BILLION long range Model S battery packs. That's a lot. I imagine there is some play in that 300 TWh estimate, but it's still going to be a ridiculously large amount.
Don't expect any battery breakthroughs using rare materials. The cathode materials need to be common/abundant. Iron, manganese, aluminum, nickel to a lesser extent. Forget cobalt.
Battery recycling needs to increase.
Mining needs to increase
If a new battery form factor or chemistry isn't scalable to high volume, it's not happening. Be wary of next latest and greatest. Profitable, large scale production is very, very difficult (see solid state batteries....30 years and still waiting).
The biggest breakthroughs need to come from the manufacturing side. Lithium-ion cells work. Suppliers need to make them faster.

Tires affect the mpg with ICE vehicles. Same as range in an EV.
I suggest you look at EV adoption in Scandinavia. No one is up in arms over tires.
No offense, but this is a non issue.
I’ve been to Scandinavia. People who live away from the large population centers in the south are not likely looking for EVs. No different than here.
My wife works for the Federal Government. They are not allowed to purchase any non-EV cars, but they don’t have anyplace to plug EVs in at her location. Typical.
the uproar from taxing the crap out of CO2 in this country would be deafening.
The Telsa/EV-bashing goalposts are in constant movement.
Yeah, I regret engaging. Pretty soon, we'll be told federal employees are being forced to buy EVs. Someone might have had an early happy hour.
Here's an article that is sure to rile the anti-Tesla folks here. You are forewarned.
that's not surprising at all. if you look at any startup, a ton of work has to be done up front until they get into steady-state operations. tesla hasn't reached it's steady state yet.
I'm not even looking for stuff to post here - It just rains down on my feed. Comparison of Telsa to Apple.
I was talking about government vehicles - agency cars, which are garaged at the federal office building, where there are no outlets to plug them in.
Aren't we?
Im saying that people who live outside of urban / suburban areas have different needs, particularly in winter climates. Your response seems to be that if the government, through tax policies, makes it painful enough to own an ICE vehicle, then even people in northern climates will buy EVs.
you can get winter tires for an EV. they may be slightly different than the standard model, or not...but you can get them. side note... i run all season grand tourings on my AWD ICE vehicle in NJ...and even when i had FWD, i never felt the need to run winter tires...so i don't know what your point is.
My point was just that by changing the tires to something other that the OE equipment, youre likely to reduce the range. The range of EV's is an issue for many, and the range with more tread depth (like a typical all season grand touring tire) is even smaller.
i put performance tires on a previous ICE vehicle, knowing that it was going to give me less mpg...but i did it anyway because i wanted the extra grip. ppl should know this about their cars. i'm no tesla apologist. i'm also one who thinks that ppl need to know what they are getting into when they buy things.
That's when he exercised the option.
Given the strike price was $500 I figure he must have bought it awhiles ago.
