Since you don't need to complete all races to get to the last tier, you don't actually need to run races rated at PR:95 (or lower, based on how many cars you get) and since the last tier actually has lower PR requirements, you don't need to upgrade to do them.

The last tier can be reached without, but that's under the assumption that all cars in the series are obtained.
