Driven wheels normally more on 2wd(front or rear).
I would have a play with pressures, when on Uniroyal Rainsports I used 33F 35R, when on F1 GSD3(awful btw) I used 35F 35R, now on Vredestein Sportrac 3's it is 33F 34R that work best, I always experiment till I get the best.
Different tyres will work better at different pressures even at same size, as some have soft sidewalls some hard etc plus other differences.
