the user manual doesn't specify that.
offsets are normally stamped on the inside of the wheel
this measurement 7.5J x 20 shown above is from the 20" OEM wheel of Kia Telluride, which is the exact same wheel size for the SC Limited
If I have to bet, SC Limited wheels should have also the same offset, +49.5mm
as for 18", here is what I found about 2021 Santa Fe 2.5T North American wheel spec:
that's the same size as SC 18" wheel, also +49.5mm offset
If any of you happens to have a chance to take the wheel off for any reason, I'd really appreciate if you could help verify that stamped offsets measurement on the OEM wheels. I believe they are +49.5mm, but still Hyundai could have changed things with SC.
While on the topic of offsets, I was trying to find some light weight, good looking 7.5jx18 aftermarket wheels, that +49.5mm offset is impossible to find. Is there any potential problem if I use wheels that are not the exact OEM offset, let's say +45mm instead of +49.5mm
Thanks in advance
