Yes Mike - you can take them off the wheels and reverse them - that means they will now sit on the other side of the car - all the inside edges become outside edges.
I've had 451's in the past, and if I don't get a bargain on my next set, they will be 452's. In the last 7 sets of tyres on two cars, the Falkens and GSD3's are the only tyres I would buy again.
