Someone putting snow tires on the rear of a front wheel drive car.

I got a like new set of studded snows on a rear of a Reliant wagon years back. I asked the old guy how it worked in the snow? He said great. The sad part was I knew the shop that he said installed them. Harhardt's Garage in Northampton.
