I needed to "downgrade" to a donut spare, so I am now selling the "upgrade" as a package. This would cost you a small fortune from the dealer.
Includes ContinentalContiPro tire on 16" steel rim, never used, plus styrofoam inserts and hold-down bolt. $150 + shipping for everything. Located in Asheville, NC.
