67 Pa. Code § 63.114
(a) General. If a vehicle is to be added to a fleet to replace a vehicle having the same registered gross weight, no additional registration fee is due to the Department for Pennsylvania registration. However, additional fees will be due for those jurisdictions which do not allow transfer credits.
(b) Estimating mileage. A carrier may, upon receiving apportioned registration for a registration year, estimate the mileage in any jurisdiction in which it has no mileage history and into or through which it desires to expand operations. The fees calculated for expanded operations will be in excess of the 100% registration percentages established at renewal.
