I not too long ago got here throughout a really fascinating video on YouTube exhibiting how an Audi EV now comes with an modern spare tire. Whereas many automakers have given up on offering a spare tire in any respect, Audi and a few others have give you an modern compromise that might make it much more possible to maintain providing spare tires in any respect.

Right here’s the video so you’ll be able to test it out for your self, however preserve scrolling as a result of I’ve loads to say about this under.

Earlier than I get into my commentary on the strengths and weaknesses of this technique, let’s summarize what it does for the individuals who don’t or can’t watch the video.

Briefly, it’s a small wheel with what seems like a tiny, tiny tire. However, the tire unfolds and expands if you put air in it (utilizing the air compressor that Audi leaves within the frunk for you). As soon as it’s totally inflated, the tire is about the identical diameter as the traditional tires, so you find yourself with one thing that’s loads like a full-size spare.

Based on the video, the tire saves fairly a little bit of house in comparison with a full-size spare, and saves round 20 kilos. This partially negates the excuse producers give us for not together with spare tire, as a result of it doesn’t take up a bunch of inside house and doesn’t weigh as a lot. So, this permits Audi to supply clients the equal of a full-sized spare with out as many downsides.

It’s price noting that the tire could be inflated and deflated a bunch of occasions, so you should utilize it to get right down to the tire store after which put it again away for the following flat tire you get. Thus, in case you don’t drive on it an excessive amount of, it may final for as much as 6 years (you’ll in all probability need to exchange the rubber on it after that lengthy for security), or possibly longer in case you wish to reside dangerously (or simply overlook about it).

How This Beats Donuts or No Spare At All

Should you’re the type of one that would simply name for roadside service and even a tow to the native tire store in case you bought a flat, this may appear silly. Roadside with included towing is an affordable add-on for should insurance policy, and car producers additionally typically embrace this throughout not less than a part of the guarantee interval. If that’s the way you roll, you’d in all probability by no means even get the increasing spare out of the trunk, making it a waste of cargo house.

However, not everybody desires to do this and even can. Should you reside exterior of the town, or wish to journey on the backroads, you could possibly be in for a protracted look forward to a tow. Worse, in case you’re someplace with no mobile sign, the tow truck simply isn’t coming until you will have a Starlink, ham radio, otherwise you like climbing to get a sign. In that state of affairs, you’re positively higher off with a spare tire that may get you again to civilization. Even in cities, many individuals simply would fairly put their very own spare on and hit the highway once more.

An expandable spare can be forward of “donut” spares in that it has the manufacturing unit tire’s circumference. This retains issues like ABS and traction management techniques glad, making for a safer journey whilst you’re on the spare.

Different options producers have been providing, like sealant/inflator kits, are additionally no substitute for a spare. It doesn’t take a lot injury to create a state of affairs the place the sealant can’t cease the leak. I discovered this out the laborious approach not lengthy after shopping for the 2018 Nissan LEAF I used to have, and ended up going to the native Llantera store to get an affordable used wheel and tire for highway journeys.

It’s Nonetheless A Poor Substitute For A Actual Full-Sized Spare

Whereas a collapsible spare is way and away higher than no spare in any respect, it’s necessary to remember the restrictions on the tire proven within the video.

Most significantly, it’s extra of a full-diameter spare than it’s a full-sized spare. It’s not solely narrower and fewer grippy in moist circumstances than the inventory tires, nevertheless it’s additionally solely constructed to go as much as 50 miles per hour. Which means that in case you’re removed from residence, and wish to make use of the spare on the freeway to get again to a tire store, you’ll must go tremendous gradual, which could be harmful if everybody else goes 80+ MPH.

Should you’re taking the EV off pavement, and it’s a rogue sharp rock that took your tire out, the increasing spare is much more iffy. It doesn’t look very robust, and would doubtless get taken out by a good gentler bump earlier than you will get to pavement once more. So, it’s not a superb answer for tenting journeys and individuals who reside on tough roads, both.

On the finish of the day, it’s actually solely a superb spare for low-speed metropolis driving not too removed from the tire store, which makes it not that significantly better than no spare in any respect.

 A Actual Full-Dimension Spare Is Often The Approach To Go

Personally, I like touring the backroads and going off pavement. I even do some very gentle off-roading in my EV (by 4×4 requirements). My Bolt EUV didn’t include a spare, nevertheless it had simply sufficient room underneath the false flooring of the cargo space to suit a spare.

I purchased the most affordable wheel I may, and have the very same tire that the opposite 4 wheels have. So, if I had been to get a flat, it will solely go away me with a TPMS warning mild till I get to the tire store to have the flat one repaired or changed. If I couldn’t get to the tire store for a number of days, it wouldn’t be an enormous deal, as a result of the automobile could be about prefer it was from the manufacturing unit, with 4 tires and no spare.

Should you’re not doing any type of off-pavement driving, it’s simply pretty much as good to discover a low-cost used tire store and decide up a used wheel and tire for lots cheaper. That is ok for freeway driving so long as you get a good used tire, and makes it simpler to get to a superb tire store on a visit as a substitute of counting on no matter janky store the following little city might need.

I do know this implies some misplaced inside cargo house, nevertheless it isn’t that unhealthy when you think about that you may put the wheel empty facet up, and put a few of your cargo inside it. I preserve my folding crossbar and a small flooring jack contained in the wheel, together with my charging twine.

Actually, the burden distinction isn’t a lot, so we’re actually simply seeing automakers low-cost out. As a substitute of struggling as a result of they’re low-cost, it’s smarter to equip your self for emergencies. However, in case you actually don’t have house for a full-size spare, increasing spares could also be a compelling possibility.
