I posted this in the "Hyundai Santa Fe Owners" Facebook Group and I'll put it here as well. It's a repeat of some of the stuff I've posted before but also a bit of new info. I'll also add a bit at the end that's not on the Santa Fe Owners Facebook Group regarding flat tires.
For those in the US who have a 2021 AWD Calligraphy or Limited and are curious about my spare tire project, I'll provide a quick update here. The Kia part number that is shared on a lot of forums as working for the Santa Fe, does not work. There is a kia part number 62800-R5000 the kia system will tell you that there is new part number 62800-R5100 that replaces the previous part number and will fit it. That part number WILL NOT fit the Santa Fe...trust me...I've tried and it does not. The 2021 Sorento however is the same exact size and the part from the 2021 Sorento (called the Carrier Spare Assembly or something similar) does fit the Santa Fe, my neighbor has a 2021 Sorento and I have taken his part off of his car and tried it on mine, he wanted it back though so sadly, I'm still without it. At this point my research hit a block...I developed kidney stones and have been sidelined...I'm finally getting back into it and have been trying to find the most cost effective solution for all of us. Currently I think we're going to be stuck with the Hyundai part, the part number is 62800-R5000 (look familiar, it's the same exact part number as Kia), I have the part on order. If you goto your local dealer and order it, it'll cost you about $400 plus tax...don't do that. I've found it for about $258 plus shipping. DO NOT ORDER IT YET. I advise everyone to let me be the guinea pig, it's hard to return auto parts that are special order and these parts are. They wanted a VIN number to order this part saying they wouldn't guaranty fit and wouldn't sell it unless it came equipped on the car when built and would not order it for me otherwise.
Other things you'll need besides the spare tire carrier.
You'll need a spare tire (obviously). You can get a full size spare if you wish, you can get a used Hyundai Santa Fe wheel off of ebay for about $95 with shipping, tire rack would be a good source though some require separate centering rings I've heard or your local tire shop. I picked up a spare tire off of ebay from a 2020 Santa Fe 165/90/r17 is the proper size for 17" and 19" factory tires, I imagine it's the same for 20" as well but am not positive, double check for yourself. It needs to be within .5" of your OEM tire diameter. There are tools online that will tell you your tire diameter, for this size spare the diameter is 28.7"
You'll need a tire jack- I picked up a bottle jack off of Amazon. There's a lot more ground clearance than you may expect under the jacking point on the Santa Fe, it's about 12" just to get pressure on the vehicle. I had to buy and return 2 jacks before I found one that was tall enough to life the Santa Fe. I picked up the Pro-Lift B-006D. Note- the piston on the jack extends higher by unscrewing the end of it, you must do this to get it high enough to raise the Santa Fe (I didn't realize this at first and almost returned it). Price on Amazon was $28
Lug Nut Wrench- I picked up a Cartman 16" Universal Anti-Slip Cross Wrench, Lug Wrench on Amazon. It was $16, it allows me to get good leverage on over torqued lug nuts that tire shops often put on. It fits in the underfloor storage, makes tire changes a lot faster than a regular lug nut wrench. EDIT- This is difficult to operate the hoist with- WORKPRO 14-Inch Universal Folding Lug Wrench, 4-Way Cross Wrench will operate the hoist, the folding sides till allow it to spin/swing inthe storage compartment when raising and lowering the hoist.
Blocks of wood- I put a couple 6" square 1.5" thick blocks of wood in my storage as well, They can work as tire chocks when changing a tire on a hill, or go under the jack to raise it up if necessary if you need it a bit higher.
I rotated my tires today using the tools listed above today. I also cheated a bit and used my 20V dewalt cordless impact driver (not impact wrench). I used a ARES 70020-1/2-Inch Drive 21MM Non-Marring Impact Lug Nut Socket from Amazon to loosen the lug nuts and to tighten them back up. I used my fingers to get them started and lugnut wrench to tighten them down to the final torque speck (for me that's grunt tight not hurt myself tight), I didn't bother looking for my torque wrench.
Sorry for the long post. I will update as soon as I get the spare tire carrier in, I'll keep my fingers crossed that it's the correct part!
New info not posted in the Facebook group:
When I first realized that my Santa Fe didn't have a spare tire and I started my quest to get one, I ordered a tire plug kit from Amazon Rhino USA 86 Piece Tire Plug Kit and watched several youtube videos on how to plug a tire. I had only one flat tire in the previous 3-4 years, but I don't trust the fix a flat kits that come with cars and don't want to get towed for a flat tire. Four weeks after having the car, I had a low tire pressure light, and 28 PSI in my back left tire 30 in my back right. I filled them both up to 35, same as the front ones. Back right stayed good and for the next week and a half the back left kept coming down slowly. Week and a half later it looked low again, I drove to the store and it was 25, I looked in the tire and there was a screw in the tire between the treads. Got home tried to jack the SUV up using the bottle jack I bought, turns out the ground clearance of the car, was 8 inches but the jacking point is 12 inches, the bottle jack only went up to about 12.5", it went back to amazon. Got out my floor jack that I use on my wifes Santa Fe, it barely got the tire off the ground (maybe a quarter inch) before maxing out). Got the tire off and found out youtube lied...it's a lot harder to plug a tire with air in it, the pliers that also come with the tire repair kits also aren't very good. If you buy a tire plug kit, add locking vice grip pliers to the shopping cart. So deflate the tire completely, and the tire was actually really easy to plug. I now understand why a lot of tire shops will plug them free, it's a 2 minute job if you know what you're doing. I put the tire back on looked at the back right and couldn't see anything wrong with it (I left the tire on). I went inside and ordered a new floor jack and a new bottle jack. The floor jack model I purchased is Big Red T83006 off of Amazon. Yesterday I rotated my tires (it was much quicker with the new jacks) and I found another screw, this one in my back right tire, plugged that one as well quite quickly this time now that I know what I'm doing. Even if you aren't going to get a spare tire installed in the car, I'd at the very least recommend a tire plug kit, bottle jack and lug nut wrench. watch a few youtube videos, you can fix the tire on the side of the road if fix a flat doesn't work. There is a compressor in the trunk to inflate the tire when you're done. It felt really satisfying fixing the tires myself even though I could have taken it to my local tire shop and had it done for free, it's also a good skill to learn. Now that I have it I'll probably never need it again. 😂
