My '93 Leg has a 135/70 R14 spare. YOu could mount the larger tire on that smaller rim (they are 185/70 R14 for mine, yours are probably different) but, as Gilles points out, that narrow rim means more flexion stress at the tread/sidewall junction which increases the likelihood of a blowout. Also, the bead will probably not sit too well since it is designed for a wider rim.
Do you want to use a full size spare on this vehicle? You may not be able to fit it in the wheel well and still have a flat cargo space floor as the space is designed for the compact. JM $0.02 here
