As others have said and this includes me, you don't have to use RFTs. Non-runflats work great. Sure, if you're super hesitant, you can buy a spare tire kit. The car actually will ride better without vibrations since RFTs are very noisy in general.
No issues will occur with TPMs or the onboard computer
. PM me if you want any advice on cheaper tires. My Delinte D8 All-Season tires are running great.
PS: I'm not the wise one. There are plenty of knowledgeable and smart members on here that know plenty about our vehicle
