Spare tire

19” Modern Spare fits in frunk.

OK, what's the consensus on the best spare to buy?

I've been looking at Modern Spare:

I have EV sports line , it fits the frunk and the the shelf can still cover with no bump.

EVSportline, Modern Spare, or EZSpare will all work.

OK, what's the consensus on the best spare to buy?

There are about 4 spare tire options specifically designed for Lucid. I went with EV Sportsline spare because I think it looks the best. Otherwise, they are all essentially the same. The spare tires are all the same size and should just barely fit in the lower well of the frunk with the cover in place.

I just ordered the EZ Spare but didn't order the accessory jack. I am looking to get a three ton jack, are there any specific brand recommendations? Do I need the rubber bumper on top of the jack (advertised to be intended to be used with Teslas) or does the jack fit into a cutout underneath the car? I don't see any lug wrench in my truck where the tow bar sits so I need to order one of those, and nothing listed on the Lucid accessories/parts website. I will reach out to their Parts Department unless someone has an aftermarket recommendation? Thanks!

I suggest you get the jack that was being sold with the spare you purchase. I purchased my spare from EV Sportsline and the jack that came with it works perfectly with the Lucid Air.

Get a lug wrench. Be aware that ground clearance with normal tire pressure is low, and with a flat tire is too low to fit a jack under the car. You will need an air pump to inflate the flat until you can place the jack. I got a compact rechargeable air pump for $40 at Costco. It fits in the glovebox, and it works very well. If you cannot inflate the flat, I believe that the chassis is stiff enough to use the other jack point.

I’m sitting on the side of the road with a flat. I ran over a pothole with the right front tire and about 20 minutes later, my tire pressure sensor went off. I was able to pull over into a gas station to swap my EZ Spare onto the car. I jacked up the car only to discover that the socket wrench heads included with the jack are too SMALL for the lug nuts on the 21” tires. Ugh!! Please learn from my experience and get the appropriately sized wrench head. I’ll keep you updated as I wait for a tow to the nearest service center (Torrance)

BD, feel your pain, I had same problem in Philly last summer, I didn't have a spare, Gonna look for one of those ez spares. They couldn't get a tire in that market (Philadelphia) for 2 days and found out rim had dent in it as well. add a week, had to drive home in rental and drive back (from WV) a week later. my wife won't drive the car now. ugh

 

[borski]

my wife won't drive the car now. ugh

Because a tire blew? Does she know all cars have tires?

 

[EVCar]

Anyone recalls the size of the lug nuts?

 

[L-Dude]

This is a great and helpful thread. I recently set up my wife's car with a full sized spare tire, and I took the time to try everything out--jack, lug wrench, etc. It was shocking how none of this stuff worked like I thought it would. The lug nuts were the wrong type for the wheel, the lug wrench I had didn't fit the lug nuts, etc etc. You pretty much need to go through a complete rehearsal in the garage to make sure you have everything you need.

I like the old days better, where the car came with everything you needed to change a tire.

Honestly, me too.

M14x1.5 is the threading. Common only on big SUVs and trucks.

YES YES and YES. Even if all the stuff in the car OEM was correct, how do you know its all there, correct and you can use it. Would you not rather learn how to use the jack, spanner, lug nuts and spare in a nice warm garage. OR on the side of the interstate in the freezing rain. Friend called one late night asking for me to drive over a breaker bar. Seems he had a flat in his newish suburban near my house. It had a small lug wrench and the lug nuts are fixed at 150 ft pounds. Now he carries a breaker bar.

While I agree that the old days of a FULL size spare, jack and spanner extension was wonderful, I read that tire quality has improved so much that the number of flat tires now is a fraction of the 1980s or before. Unless you have LOW profile tires on a heavy car.....

Thanks, and glad to see you back.
Since you're one of the de facto technical advisors for the forum, what do you think about the idea of changing the 22" rear wheels on the Gravity into 21", just like the front, so that one can have a spare tire usable on both axles? The car's efficiency and performance likely will be impacted but safe?

Thanks, I better answer quick before I am found "excommunicado" again!

I am speaking from GENERAL tire and handling knowledge. I know nothing about the Gravity. First, you may not need to change the rear wheels.

You need to determine what the actual tire diameter of the front and rear tires/wheels are. It could be if the diameters are the same (or close), you can use the same spare for both. I had a Porsche that did that: staggered width AND a different diameter wheel size on front and back. But all four were the same overall diameter. So one collapsing spare of THAT diameter worked. Remember, its not the wheel size that matters for a spare, its the overall diameter that is critical.

Case in point, my Lucid had a bad rear tire, 265/35 with a 21" diameter wheel. For a few days, I put on a winter snow tire/wheel. 19" wheel - 245 width, But both the 19 and 21 wheel/tires were the same overall diameter. it drove fine around town for a day or so.

Now, I believe if the front and rear wheel/tire diameter are more than an inch or so different diameter, that could be tricky. In some cars, like Audis, it could never be done becuase of the quattro system linking all four wheels. But since we have separate front and rear motors, I am TOLD that the Lucid can handle small diameter overall tire diameter differences, and not be unsafe.

If you get the tire size from the specs, you can find all information online. If you know the exact tire, the manufacturers will provide, online, exact tire diameters. I used to use the online tire calculators all the time to do Plus 1, Plus 2 or even Minus 1 tire changes. TO a point, there is flexibility.

Thanks very much. This is very helpful.
Will do some digging.

Great information. And easy solution. Only one size spare needed to fit front and back

OEM front to rear Tire diameter difference is only 2.2 %. Minor. Very acceptable. 3% or less is insignificant.

And Rule of thumb is to keep replacement tires within 3% or less difference. So, a spare with an outside diameter anywhere from 30.2 to 30.9 will fit both front and back, staying well with in the 3%.
