Tesla's reason for not adding spare tires, doesn't make sense.
- Thread starter gflar
- Start date
Then Tesla needs to provide 2 versions of FSD: 1 to run with cars having spare tires, 1 to run with cars having no spare tires.Perhaps Elon could be convinced to add a spare tire if the Tesla engineers could convince him it was needed for the windshield washing system like VW used to do in the 60's?

The pot calling the kettle black. But it's the pot that's off topic, not the kettle.
Cars having no spare tires since 2017:
That includes most popular and top of the line car models.

No, actually that’s cars with no spare Up to 2017. Regardless this entire thread is a train wreck at this point. Most cars from Most OEM’s won’t have a spare. Complain and move on or get one if you feel the need.
To do a plug?
That's what I'm talking about. A plug is a minute or two. Taking the wheel off, demounting the tire takes a LOT more time.
Any legitimate tire shop will completely remove the tire from the wheel, cut out a section of foam (looks like window trim insulation foam), rough up the inner surface of the tire around the hole, apply cement, and insert a mushroom shaped patch/plug, pushing it through the hole from the inside out. Tech will use a small roller to press the "mushroom" part to assure total contact, then re-cement the foam that was removed, remount the tire, inflate, and balance.
A plug, done in an emergency, is only pushed through from the outside. You are correct, the tire is NOT dismounted.

Tire is removed for a patch. @stopcrazypp was talking about a patch. I did not know tire shops did plugs, that is usually done by DIY in a pinch. No need to remove tire for a plug.

I was talking about a patch (or a combo patch/plug). In context, you were talking about "reputable" shops. I know of no reputable shop that does plugs from the outside.
Here's the repair guide for a tire without the foam:
https://www.rematiptop.com/assets/t...Nail-Hole-Repair-Procedures-Wall-Chart-v9.pdf
You will notice it is exactly the same other than cutting out the foam.
Here's a one piece combo patch/plug:
Here's a patch (that typically is applied after plugging a stem into the hole, which is why it's call a "two piece" procedure):
As I already said, the foam is irrelevant to a standard plug (which users apply themselves), given it is applied from the outside and doesn't rely on sticking on the inside surface of the wheel.
To make it clear, people talking about shops (which does patches as above) refusing to fix are because when such tires first came out, they were unaware it was as simple as cutting out the foam. Now the official repair guides make it clear it really is that easy.
In case you doubt these instructions, even Continental, the manufacturer, links to Rema's tire repair guide for repairing their Contisilent tires:
Tire Repair
Michelin does not appear to have public repair guides on the internet, but they say: "Repairs of all tires must be of the combined-plug-and-inside-patch type." Practically all manufacturers claim the same, which is why shops will not do plugs alone.

Not on list, last car of mine was a 2017 Hyundai Sonata Hybrid. It didn't have a spare.

Do spare engines count?
Here is a good Tesla road trip. Between Bakersfield and Victorville. I'm not into trains but this is very cool.
The Tehachapi Loop. Only place in the world where a train goes over the top of it self.

Plugs faded away when the radial tire was introduced. Because radial tires flex the plug lets air slowly weep. It will get you by for a couple 1,000 miles, but not a permanent fix.
That being said, I've plugged my own tires until I had time for a repair.
Not trying to sound combative. I have a 21 gal compressor and full complement of tools, etc. I fill up lawnmower, truck, etc. Wont rely on battery when I know corded will just work whenever and I will only use in emergency. So far, I have never filled Tesla tires. Actually let a bit of air out of them to soften ride

Check out this thread. Impossible to keep up with. Schizophrenic at best. It is the most active thread and the most unfocused thread in all of TMC history. If one can't handle talking about tire repair on a spare tire thread, don't go here:
Tesla, TSLA & the Investment World: the Perpetual Investors' Roundtable
Welcome to the 2019 Investors' Roundtable. This year, we are not going to try to split discussions between a "Market Action" and a "General" thread, as years of experience has shown all are too enthusiastic about putting their opinions and observations in a fairly random dispersion. So post...

Probably. I got one when I had a Chevy Volt, but I only used it on long trips. Took up a lot of space relative to the car size.

US government mandated a dramatic increase in fleet gas mileage by 2026, at least a 10 mpg increase over the 2021 mandate. In Europe missing the mandated levels results in huge fines. This puts a pinch on ICE car manufacturers, they will go to great lengths to gain 0.1 mpg, dropping the spare is an easy way to make an immediate difference.
My wife's 2008 BMW X5, along with other models from that time period, has a parasitic battery drain that was exacerbated by choices BMW made to gain a fraction of a percent in gas mileage. They programmed the alternator to not come on unless the car is on the interstate driving at interstate speed. This gained them a fraction of a % on fleet mileage. But combined with a parasitic drain and driving around town, the battery would die with no warning and the car couldn't be jump started. It can't even be put into neutral for towing. The partial solution was to reprogram the alternator to function at lower speeds, and shut down all the computers in a much shorter time after shutting the car off.
So, yeah, the manufacturers play games to squeeze out the last bit of gas mileage in ICE cars, and given the unnecessary importance placed on range by car buyers it is not a surprise EV manufacturers do the same.
