Then Costco said it was required (implication was by law) to put the new tire on the rear, and move the slightly used rear one to the forward. I had no problem with that, but I wonder if:
- That is a genuine legal requirement or not? (This is in California, so it could be a state law, not a federal law.)
- If not required by law, is this an industry standard?
- If the answer to either of the above is YES, what is the rationale behind it. I always believed it was safer to have the best tires on the front, to decrease the danger of loosing steering control during a blowout at speed, thinking that one won't be likely to lose steering control if a rear tire blows.
