Are you running a radial/bias ply mix?

If so, did you notice any issues I should be concerned about?

This last time I was running bias ply slicks in the rear and radial street tires (maxxis vr1) up front, no issues, no issues with skinnies up front either.

Running on the slicks the car is a little different to drive on, it moves around a bit, like when you shift going down the track you feel the car squirm a little.
