You can...but I would not recommend it. I used to run radials up front and Hoosier Quick Time Pro's on the rear, and it worked (ran it like this for 8-9 years), but it was not real stable going down the road (it would "hunt" around even when going straight). Once I switched to drag radials on the rear to match the radials up front the car was MUCH more stable all the way around. Makes me wish I did it right the first time, but oh well...live and learn I suppose.
