The manual for the 2023 ID.4 says that chains are not approved for any 20" tires and in all cases should only be put on the rear tires. It looks like there are some other options that are perhaps lower profile, like these Michelin chains:

They have a size that fits the rear 2023" Pro S AWD tires (255/45 R20), the EVO 16. Has anyone tried these or have any suggestions for traction devices that could be used on the rear 20" Pro S AWD tires? We live in California and they sometimes impose controls that require you to carry chains even if you have AWD.
Thanks!
