I haven't seen any Sonata spare wheels that are 18". If you do, please show. Seriously. Would love to find an alternative.

It didn't clear mine.
I have a shop down the street that had the OEM Hyundai spare tire/rim.....
I had them turn the wheel very very slowly to see if it would clear my calipers and it wouldn't. I needed about a 1/16 of an inch more clearance in the rear. I needed about 1/8 of an inch in the front. Not worth risking tearing the red off my calipers.

Thanks for the reminder. I’ll try to install them this week. The height of the tire is concerning; it is ~1” taller than the factory tire.
Was this an 18” or 19” spare? The one I have is a 19” spare.

Thanks for the compliment!
Didn't see a Hyundai Equus spare on eBay right now for a decent price, but there is a Kia K900 spare. I believe it's the same as a Equus. Thought about buying it to confirm.

Yes this is the same spec as the Hyundai spare. Lug nut size is M12 instead of M14 so note that you might need to ream the holes bigger.
Center bore is bigger than the M3 so you can consider getting a 67.1 to 64.1 adapter ring. But since this is for a spare you probably don't need to worry about having perfect balance.

I already have a 19” Hyundai spare and the studs don’t need to be reamed.
I also already commented that an adapter will be needed.

I got the 17". It fit, but caused clunky noises when driving. I sent it back and got the Modern Spare.
I know I'm way late to the party here. Has this been well tested? Are you all certain about model 3 not minding having different circumference tires on each side of the car? I know it doesn't use limited slip differentials (clutches or such), but won't this trigger some level of slip detection if one side is different than the other? It's all good to get something with the same ratios printed on the sidewall, however, different tires (even from the same mfg) can vary significantly from those numbers. Whether this causes damage or just digital confusion I do not know. Seems like it would be a good idea to test travel distances per revolution and adjust spare inflation accordingly. Unless of course someone has driven and shown different radius tires don't cause a problem?

These are temporary spares. They are not supposed to be used for driving long distances and at high speed. And, with that, if you're going to compare the stock 235/45-18 tire vs. the 135/80-18 tire, the revs/mi is 766 vs. 761. An indicated 50 mph on a stock size tire, would mean you would travel at 50.4 mph on the space saver spare.
