Some things are much easier with ODB electronics though. Like if a cylinder is misfiring, you pull out a code scanner and see exactly which spark plug needs to get replaced.

Good luck replacing it without giving the car computer mental breakdown. I replaced my car's tire once and all the sensors went crazy until engine light came on. They are not making those car software forgiving.

There are a few procedures. You just need to tell the car about the new tires so it doesn't keep looking for the old.
