Tire thoughts.....

Paul,
You don't want to run a bias-ply tire on the rear and a radial tire on the front.
From Michelin's website:
DO NOT mix radial and non-radial tires on a vehicle. If mixing tires is unavoidable, NEVER mix radial and non-radial tires on the same axle. If two radial and two non-radial tires are installed on a vehicle, the two radials MUST be installed on the rear axle and the two non-radials on the front axle.
IIRC it's due to the way that the two different types of of tires react to steering inputs and it results in the car having too much oversteer.
